Da W, Chen Q, Shen B. The current insights of mitochondrial hormesis in the occurrence and treatment of bone and cartilage degeneration. Biol Res 2024; 57:37.

Abstract
It is widely acknowledged that aging, mitochondrial dysfunction, and cellular phenotypic abnormalities are intricately associated with the degeneration of bone and cartilage. Consequently, gaining a comprehensive understanding of the regulatory patterns governing mitochondrial function and its underlying mechanisms holds promise for mitigating the progression of osteoarthritis, intervertebral disc degeneration, and osteoporosis. Mitochondrial hormesis, referred to as mitohormesis, represents a cellular adaptive stress response mechanism wherein mitochondria restore homeostasis and augment resistance capabilities against stimuli by generating reactive oxygen species (ROS), orchestrating unfolded protein reactions (UPRmt), inducing mitochondrial-derived peptides (MDP), instigating mitochondrial dynamic changes, and activating mitophagy, all prompted by low doses of stressors. The varying nature, intensity, and duration of stimulus sources elicit divergent degrees of mitochondrial stress responses, subsequently activating one or more signaling pathways to initiate mitohormesis. This review focuses specifically on the effector molecules and regulatory networks associated with mitohormesis, while also scrutinizing extant mechanisms of mitochondrial dysfunction contributing to bone and cartilage degeneration through oxidative stress damage. Additionally, it underscores the potential of mechanical stimulation, intermittent dietary restrictions, hypoxic preconditioning, and low-dose toxic compounds to trigger mitohormesis, thereby alleviating bone and cartilage degeneration.

Abstract
The impact of mitochondrial dysfunction on the pathogenesis of cardiovascular disease is increasing. However, the precise underlying mechanism remains unclear. Mitochondria produce cellular energy through oxidative phosphorylation while regulating calcium homeostasis, cellular respiration, and the production of biosynthetic chemicals. Nevertheless, problems related to cardiac energy metabolism, defective mitochondrial proteins, mitophagy, and structural changes in mitochondrial membranes can cause cardiovascular diseases via mitochondrial dysfunction. Mitofilin is a critical inner mitochondrial membrane protein that maintains cristae structure and facilitates protein transport while linking the inner mitochondrial membrane, outer mitochondrial membrane, and mitochondrial DNA transcription. Researchers believe that mitofilin may be a therapeutic target for treating cardiovascular diseases, particularly cardiac mitochondrial dysfunctions. In this review, we highlight current findings regarding the role of mitofilin in the pathogenesis of cardiovascular diseases and potential therapeutic compounds targeting mitofilin.

Chem Biol Interact 2024; 388:110852.

Abstract
Characterized by bone mass loss, osteoporosis is an orthopedic disease typically found in postmenopausal women and aging individuals. Consistent with its pathogenesis summarized as an imbalance in bone formation/resorption, current pharmacologically therapeutic strategies for osteoporosis mainly aim to promote bone formation or/and inhibit bone resorption. However, few effective drugs with mild clinical side effects have been developed, making it a well-concerned issue to seek appropriate drugs for osteoporosis. In this study, we investigated the effect of ellagic acid (EA) on osteogenesis in vitro and in vivo and searched for its molecular mechanism. Here, we showed that EA promoted osteogenic differentiation of MSCs, increased mRNA and protein expression levels of osteoblast marker genes Runt-related transcription factor2, Osterix, Alkaline phosphatase, Collagen type I alpha 1, Osteopontin and Osteocalcin. Furthermore, ovariectomized mice with orally administered EA (10 mg/kg, 50 mg/kg) had significantly higher bone mass than those in controls. And experiments such as fluorescence double-labeling and enzyme-linked immunosorbent assay also demonstrated that EA could promote osteogenesis in vivo. To probe the molecular mechanism of EA, we performed RNA sequencing analysis using EA-treated BMSCs. Significant up-regulation of SMAD2/3 transcription factors was identified by RNA-seq, and it was confirmed in vitro that EA promoted bone formation by activating the SMAD2/3 signaling pathway. Evidence from our present experiments indicates that EA may be a promising candidate for clinical treatment for osteoporosis in future.

Abstract
Mitochondria plays a role in cell differentiation and apoptosis processes. Maintaining mitochondrial function is critical, and this involves various aspects of mitochondrial quality control such as protein homeostasis, biogenesis, dynamics, and mitophagy. Osteoporosis, a metabolic bone disorder, primarily arises from two factors: the dysregulation between lipogenic and osteogenic differentiation of aging bone marrow mesenchymal stem cells, and the imbalance between osteoblast-mediated bone formation and osteoclast-mediated bone resorption. Mitochondrial quality control has the potential to mitigate or even reverse the effects. Among the Sirtuin family, consisting of seven Sirtuins (SIRT1-7), SIRT1-SIRT6 play a crucial role in maintaining mitochondrial quality control. Additionally, SIRT1, SIRT3, SIRT6, and SIRT7 are directly involved in normal bone development and homeostasis by modulating bone cells. However, the precise mechanism by which these Sirtuins exert their effects remains unclear. This article reviews the impact of various aspects of mitochondrial quality control on osteoporosis, focusing on how SIRT1, SIRT3, and SIRT6 can improve osteoporosis by regulating mitochondrial protein homeostasis, biogenesis, and mitophagy. Furthermore, we provide an overview of the current state of clinical and preclinical drugs that can activate Sirtuins to improve osteoporosis. Specific Sirtuin-activating compounds are effective, but further studies are needed. The findings of this study may offer valuable insights for future research on osteoporosis and the development of clinical prevention and therapeutic target strategies.

Abstract
Osteoporosis (OP) is a skeletal disorder characterized by decreased bone density, alterations in bone microstructure, and increased damage to the bones. As the population ages and life expectancy increases, OP has become a global epidemic, drawing attention from scientists and doctors. Because of polyphenols have favorable antioxidant and anti-allergy effects, which are regarded as potential methods to prevent angiocardipathy and OP. Polyphenols offer a promising approach to preventing and treating OP by affecting bone metabolism, reducing bone resolution, maintaining bone density, and lowering the differentiation level of osteoclasts (OC). There are multiple ways in which polyphenols affect bone metabolism. This article provides an overview of how polyphenols inhibit oxidative stress, exert antibacterial effects, and prevent the occurrence of OP. Furthermore, we will explore the regulatory mechanisms and signaling pathways implicated in this process.

Abstract
Bone defects in osteoporosis usually present excessive reactive oxygen species (ROS), abnormal inflammation levels, irregular shapes and impaired bone regeneration ability; therefore, osteoporotic bone defects are difficult to repair. In this study, an injectable thermosensitive hydrogel poly (D, L-lactide)-poly (ethylene glycol)- poly (D, L-lactide) (PLEL) system containing resveratrol (Res) and dexamethasone (DEX) is designed to create a microenvironment conducive to osteogenesis in osteoporotic bone defects. This PLEL hydrogel is injected and filled irregular defect areas and achieving a rapid sol-gel transition in situ. Res has a strong anti-inflammatory effects that can effectively remove excess free radicals at the damaged site, guide macrophage polarization to the M2 phenotype, and regulate immune responses. Additionally, DEX can promote osteogenic differentiation. In vitro experiments showed that the hydrogel effectively promoted osteogenic differentiation of mesenchymal stem cells, removed excess intracellular ROS, and regulated macrophage polarization to reduce inflammatory responses. In vivo experiments showed that the hydrogel promoted osteoporotic bone defect regeneration and modulated immune responses. Overall, this study confirmed that the hydrogel can treat osteoporotic bone defects by synergistically modulating bone damage microenvironment, alleviating inflammatory responses, and promoting osteogenesis; thus, it represents a promising drug delivery strategy to repair osteoporotic bone defects.

Abstract
In cell transplantation therapy, mesenchymal stem cells(MSCs)are ideal seed cells due to their easy acquisition and cultivation, strong regenerative capacity, multi-directional differentiation abilities, and immunomodulatory effects. Autologous MSCs are better applicable compared with allogeneic MSCs in clinical practice. The elderly are the main population for cell transplantation therapy, but as donor aging, MSCs in the tissue show aging-related changes. When the number of generations of in vitro expansion is increased, MSCs will also exhibit replicative senescence. The quantity and quality of MSCs decline during aging, which limits the efficacy of autologous MSCs transplantation therapy. In this review, we examine the changes in MSC senescence as a result of aging, discuss the progress of research on mechanisms and signalling pathways of MSC senescence, and discuss possible rejuvenation strategies of aged MSCs to combat senescence and enhance the health and therapeutic potential of MSCs.

Abstract
Significance: The architecture of the mitochondrial network and cristae critically impact cell differentiation and identity. Cells undergoing metabolic reprogramming to aerobic glycolysis (Warburg effect), such as immune cells, stem cells, and cancer cells, go through controlled modifications in mitochondrial architecture, which is critical for achieving the resulting cellular phenotype. Recent Advances: Recent studies in immunometabolism have shown that the manipulation of mitochondrial network dynamics and cristae shape directly affects T cell phenotype and macrophage polarization through altering energy metabolism. Similar manipulations also alter the specific metabolic phenotypes that accompany somatic reprogramming, stem cell differentiation, and cancer cells. The modulation of oxidative phosphorylation activity, accompanied by changes in metabolite signaling, reactive oxygen species generation, and adenosine triphosphate levels, is the shared underlying mechanism. Critical Issues: The plasticity of mitochondrial architecture is particularly vital for metabolic reprogramming. Consequently, failure to adapt the appropriate mitochondrial morphology often compromises the differentiation and identity of the cell. Immune, stem, and tumor cells exhibit striking similarities in their coordination of mitochondrial morphology with metabolic pathways. However, although many general unifying principles can be observed, their validity is not absolute, and the mechanistic links thus need to be further explored. Future Directions: Better knowledge of the molecular mechanisms involved and their relationships to both mitochondrial network and cristae morphology will not only further deepen our understanding of energy metabolism but may also contribute to improved therapeutic manipulation of cell viability, differentiation, proliferation, and identity in many different cell types.

Abstract
BACKGROUND Osteopenia has been well documented in adolescent idiopathic scoliosis (AIS). Bone marrow stem cells (BMSCs) are a crucial regulator of bone homeostasis. Our previous study revealed a decreased osteogenic ability of BMSCs in AIS-related osteopenia, but the underlying mechanism of this phenomenon remains unclear. METHODS A total of 22 AIS patients and 18 age-matched controls were recruited for this study. Anthropometry and bone mass were measured in all participants. Bone marrow blood was collected for BMSC isolation and culture. Osteogenic and adipogenic induction were performed to observe the differences in the differentiation of BMSCs between the AIS-related osteopenia group and the control group. Furthermore, a total RNA was extracted from isolated BMSCs to perform RNA sequencing and subsequent analysis. RESULTS A lower osteogenic capacity and increased adipogenic capacity of BMSCs in AIS-related osteopenia were revealed. Differences in mRNA expression levels between the AIS-related osteopenia group and the control group were identified, including differences in the expression of LRRC17 , DCLK1 , PCDH7 , TSPAN5 , NHSL2 , and CPT1B . Kyoto Encyclopedia of Genes and Genomes enrichment analyses revealed several biological processes involved in the regulation of autophagy and mitophagy. The Western blotting results of autophagy markers in BMSCs suggested impaired autophagic activity in BMSCs in the AIS-related osteopenia group. CONCLUSION Our study revealed that BMSCs from AIS-related osteopenia patients have lower autophagic activity, which may be related to the lower osteogenic capacity and higher adipogenic capacity of BMSCs and consequently lead to the lower bone mass in AIS patients.

Abstract
Orthodontic treatment in older adults is more difficult than in younger adults, partially due to delayed osteogenesis caused by senescence of human periodontal ligament stem cells (hPDLSCs). The production of brain-derived neurotrophic factor (BDNF) which regulates the differentiation and survival of stem cells decreases with age. We aimed to investigate the relationship between BDNF and hPDLSC senescence and its effects on orthodontic tooth movement (OTM). We constructed mouse OTM models using orthodontic nickel‑titanium springs and compared the responses of wild-type (WT) and BDNF+/- mice with or without addition of exogenous BDNF. In vitro, hPDLSCs subjected to the mechanical stretch were used to simulate the cell stretch environment during OTM. We extracted periodontal ligament cells from WT and BDNF+/- mice to evaluate their senescence-related indicators. The application of orthodontic force increased BDNF expression in the periodontium of WT mice, while the mechanical stretch increased BDNF expression in hPDLSCs. Osteogenesis-related indicators, including RUNX2 and ALP decreased and cellular senescence-related indicators such as p16, p53 and β-galactosidase increased in BDNF+/- mice periodontium. Furthermore, periodontal ligament cells extracted from BDNF+/- mice exhibited more senescent compared with cells from WT mice. Application of exogenous BDNF decreased the expression of senescence-related indicators in hPDLSCs by inhibiting Notch3, thereby promoting osteogenic differentiation. Periodontal injection of BDNF decreased the expression of senescence-related indicators in periodontium of aged WT mice. In conclusion, our study showed that BDNF promotes osteogenesis during OTM by alleviating hPDLSCs senescence, paving a new path for future research and clinical applications.

Abstract
Spatiotemporal Immune disorder is a key factor leading to the failure of bone tissue healing. It is of vital importance to accurately suppress excessive peak immune response within 24-48 h of the injury and so regulate the spatiotemporal osteoimmune disturbance of bones. In this study, Ultrasound Controlled "Explosive" (UCE) hydrogels were prepared from gelatin-hyaluronic acid methacrylate hydrogels loaded with resveratrol nanobubbles produced by double emulsification through a condensation reaction. Such materials innovatively enable ultrasound-controlled RES release for precise regulation of spatiotemporal osteoimmune disorders. Under an ultrasonic power level of 1.5 W/cm2, the rate of effectively released RES through the blast of UCE hydrogels reached 38.14 %. And compared with the control group, the in vivo inhibition of inflammation and osteogenesis effects of UCE hydrogels were more effective, respectively. As suggested by the results, the excessive local inflammatory response was inhibited by the release of resveratrol, the temporospatial disorder of bone immune was precisely regulated, and as a result, the process of bone repair was accelerated. Altogether, this study confirms that the newly created UCE Hydrogels effectively promote bone repair by intervening peak inflammation during the early phase of fracture healing.

Abstract
Aluminum (Al) is widely used for water purification, cooking pots, cosmetic and pharmaceutical preparations, toothpaste tubes, and food processing industries. Although the transport in the digestive tract is very poor but if the load is high, it can be absorbed and accumulated. About 50-70% of Al accumulates in the bones and can have an impact on human health. Resveratrol (RES), isolated from tempeh as an Indonesian food ingredient, can increase cell viability and has promising cytoprotective effects. RES has the capacity to interact with oxidative stress, so it has the potential as a therapy in bone repair. Therefore, this study aimed to evaluate the effect of RES on the number of osteocytes and bone marrow cells in Al-induced mice. Swiss Webster mice were divided into four groups: (1) untreated groups, (2) AlCl3-treated groups, (3) Al+Res5 treated groups, and (4) Al+Res10 treated groups. Al dose 200 mg/kg body weight was administered intraperitoneally. RES was given one hour after administration of Al, with doses of 5 and 10 mg/kg Body Weight. Al and RES administration is carried out for one month. All mice were sacrificed, and mouse bones were isolated for histological preparations and a half for genotoxic assays. Bone marrow cells were collected and stained with My Grunwald. The number of micronuclei polychromatic erythrocytes (MNPCE) was examined in 1,000 PCEs per animal. The number of PCEs is counted by at least 200 erythrocytes (PCE + NCE) per animal. The results showed that the administration of Al significantly increased the number of micronuclei (MN) but after administration of RES at doses of 5 and 10 mg/kg Body Weight significantly reduced the number of MN in bone marrow cells. A dose of RES 10 mg/kg BW stimulates proliferation and increases the number of osteocytes in bone significantly. It can be concluded that Al can cause genotoxicity in bone marrow cells and RES is anti-genotoxic and can stimulate osteocyte proliferation.

Abstract
The organelle modulation has emerged as a crucial contributor to the organismal homeostasis. The mesenchymal stem cells (MSCs), with their putative functions in maintaining the regeneration ability of adult tissues, have been identified as a major driver to underlie skeletal health. Bone is a structural and endocrine organ, in which the organelle regulation on mesenchymal stem cells (MSCs) function has most been discovered recently. Furthermore, potential treatments to control bone regeneration are developing using organelle-targeted techniques based on manipulating MSCs osteogenesis. In this review, we summarize the most current understanding of organelle regulation on MSCs in bone homeostasis, and to outline mechanistic insights as well as organelle-targeted approaches for accelerated bone regeneration.

Abstract
Aging is a gradual and irreversible pathophysiological process. It presents with declines in tissue and cell functions and significant increases in the risks of various aging-related diseases, including neurodegenerative diseases, cardiovascular diseases, metabolic diseases, musculoskeletal diseases, and immune system diseases. Although the development of modern medicine has promoted human health and greatly extended life expectancy, with the aging of society, a variety of chronic diseases have gradually become the most important causes of disability and death in elderly individuals. Current research on aging focuses on elucidating how various endogenous and exogenous stresses (such as genomic instability, telomere dysfunction, epigenetic alterations, loss of proteostasis, compromise of autophagy, mitochondrial dysfunction, cellular senescence, stem cell exhaustion, altered intercellular communication, deregulated nutrient sensing) participate in the regulation of aging. Furthermore, thorough research on the pathogenesis of aging to identify interventions that promote health and longevity (such as caloric restriction, microbiota transplantation, and nutritional intervention) and clinical treatment methods for aging-related diseases (depletion of senescent cells, stem cell therapy, antioxidative and anti-inflammatory treatments, and hormone replacement therapy) could decrease the incidence and development of aging-related diseases and in turn promote healthy aging and longevity.

Abstract
Bone reconstruction includes a steady state system of bone formation and bone absorption. This tight coupling requires subtle coordination between osteoblasts and osteoclasts. If this balance is broken, it will lead to bone mass loss, bone density reduction, and bone metabolic diseases, such as osteoporosis. Polyphenols in Chinese herbal medicines are active ingredients in plant extracts with high safety and few side effects, and they can play a role in affecting bone formation and bone resorption. Some of these have estrogen-like effects and can better target bone health in postmenopausal women. The purpose of this review is to provide comprehensive information on the mechanisms underlying the relationship between traditional Chinese medicine polyphenols and bone formation or bone resorption.

Abstract
An elevated bone microenvironmental reactive oxygen species (ROS) level is a hallmark of osteoporosis that often leads to the dysfunction of bone-related mesenchymal stem cells (MSCs), which would induce MSC senescence and severely undermine their osteoblastic potential. Herein, we report the in situ construction of bone microenvironment-responsive biofunctional metal-organic framework (bio-MOF) coating on the titanium surface through the coordination between p-xylylenebisphosphonate (PXBP) and Ce/Sr ions by a hydrothermal method. Taking advantage of the anchored Ce and Sr ions, the AHT-Ce/SrMOF implants demonstrate on-demand superoxide dismutase and catalase-like catalytic activities to decompose ROS in MSCs and restore their mitochondrial functions. In vitro analysis showed that the AHT-Ce/SrMOF implants substantially activated the AMP-activated protein kinase (AMPK) signaling pathway in MSCs and reduced the ROS levels. Meanwhile, MSCs grown on AHT-Ce/SrMOF implants displayed significantly higher expressions of the mitochondrial fission marker (DRP1), mitochondrial fusion marker (MFN2 and OPA1), and mitophagy marker (PINK1 and LC3) than those of the AHT-CeMOF and AHT-SrMOF groups, which indicated that the bio-MOF could amend mitochondrial function in MSCs to reverse senescence. In vivo evaluations showed that the bio-MOF-coated Ti implants could restore MSC function in the implant site and promote new bone formation, leading to improved osteointegration in osteoporotic rat. This study may improve implant-mediated fracture healing in the clinics.

Abstract
The loss of tissues and organs is a major challenge for biomedicine, and the emerging 3D bioprinting technology has brought the dawn for the development of tissue engineering and regenerative medicine. Chitosan-based supramolecular hydrogels, as novel biomaterials, are considered as ideal materials for 3D bioprinting due to their unique dynamic reversibility and fantastic biological properties. Although chitosan-based supramolecular hydrogels have wonderful biological properties, the mechanical properties are still under early exploration. This paper aims to provide some inspirations for researchers to further explore. In this review, common 3D bioprinting techniques and the properties required for bioink for 3D bioprinting are firstly described. Then, several strategies to enhance the mechanical properties of chitosan hydrogels are introduced from the perspectives of both materials and supramolecular binding motifs. Finally, current challenges and future opportunities in this field are discussed. The combination of chitosan-based supramolecular hydrogels and 3D bioprinting will hold promise for developing novel biomedical implants.

Abstract
BMSCs Osteogenic differentiation is beneficial to the construction of bone tissue engineering. Oxidative stress can affect BMSCs differentiation. MiR-141 regulates BMSCs proliferation. However, MiR-141’s role in BMSCs osteogenic/adipogenic differentiation under oxidative stress
is unclear. Mice BMSCs were assigned into control group; oxidative stress group; and si-MiR-141 group followed by detecting miR-141 level. After 14 days of osteogenesis or adipogenesis induction, RUNX2, OPN and FABP4 mRNA level was analyzed together with analysis of ROS and SOD content, ALP
activity and TGFβ/smad signaling protein level by Western blot. Under oxidative stress, MiR-141 was significantly upregulated and RUNX2 and OPN level was decreased, along with increased ROS content and FABP4 level, reduced SOD and ALP activity and expression of TGFβ1
and smad2 (P < 0.05). Transfection of MiR-141 siRNA into BMSCs under oxidative stress down-regulated MiR-141, significantly upregulated RUNX2 and OPN, reduced ROS, elevated SOD activity, downregulated FABP4, and increased ALP activity and TGFβ1 and smad2 expression (P
< 0.05). In conclusion, MiR-141 expression is increased in BMSCs under oxidative stress. Down-regulating MiR-141 improves the redox imbalance through TGFβ/smad signaling pathway, promotes osteogenic differentiation of BMSCs and inhibits differentiation to adipocytes.

Orcinol Glucoside Improves Senile Osteoporosis through Attenuating Oxidative Stress and Autophagy of Osteoclast via Activating Nrf2/Keap1 and mTOR Signaling Pathway. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:5410377. [PMID: 35585885 PMCID: PMC9110208 DOI: 10.1155/2022/5410377] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/08/2022] [Revised: 02/28/2022] [Accepted: 04/04/2022] [Indexed: 12/21/2022]
Abstract
Oxidative stress and autophagy play essential roles in the development of senile osteoporosis which is characterized by disrupted osteoclastic bone resorption and osteoblastic bone formation. Orcinol glucoside (OG), a phenolic glycoside isolated from Curculigo orchioides Gaertn, possesses antiosteoporotic properties. This study examined the protective effects of OG on bone loss in SAMP6 mice and explored the underlying mechanisms. The osteoporotic SAMP6 mice were treated with OG oral administration. RAW264.7 cells were induced to differentiate into osteoclast by RANKL and H2O2 in vitro and received OG treatment. The results demonstrated that OG attenuated bone loss in SAMP6 mice and inhibited the formation and bone resorption activities of osteoclast and reduced levels of oxidative stress in bone tissue of SAMP6 mice and osteoclast. Furthermore, OG activated Nrf2/Keap1 signaling pathway and enhanced the phosphorylation of mTOR and p70S6K which are consequently suppressing autophagy. Of note, the effect of OG on Nrf2/Keap1 signaling was neutralized by the mTOR inhibitor rapamycin. Meanwhile, the inhibitory effect of OG on autophagy was reversed by the Nrf2 inhibitor ML385.Conclusively, OG attenuated bone loss by inhibiting formation, differentiation, and bone resorption activities of osteoclast. Regulation of Nrf2/Keap1 and mTOR signals is a possible mechanism by which OG suppressed oxidative and autophagy of osteoclasts. Thus, OG prevented senile osteoporosis through attenuating oxidative stress and autophagy of osteoclast via activating Nrf2/Keap1 and mTOR signaling pathway.

Abstract
Diabetes mellitus (DM) is a worldwide chronic epidemic disease of impaired glucose metabolism. Transplantation of mesenchymal stem cells (MSCs) is considered a promising emerging treatment strategy for diabetes. However, the harsh internal environment of DM patients can inhibit the treatment effects of transplanted MSCs. Fortunately, this adverse effect can be reversed by resveratrol (Res). Therefore, we investigated and summarized relevant studies on the combined treatment of diabetes with MSCs and resveratrol. This review presents the therapeutic effects of this combination therapy strategy on DM in glycemic control, anti-inflammatory, anti-oxidative stress and anti-fibrotic. Moreover, this review explained the mechanisms of MSCs and resveratrol in diabetes treatment from 3 aspects, including promoting cell survival and inhibiting apoptosis, inhibiting histiocyte fibrosis, and improving glucose metabolism. These findings help to understand in-depth mechanisms of the treatment of DM and help to propose a potential treatment strategy for DM and its complications.

Abstract
Musculoskeletal system disorders are among the most common age-related conditions worldwide. All associated with a degeneration of the supporting tissues under pro-inflammatory micro- and macro-environments, the erosion of cartilage and later of bones, are the main hallmarks of these pathologies. Affected chondrocytes, osteoblasts and synoviocytes, that are all critical actors in the bone and cartilage defects exhibit mitochondrial dysfunction that develops immediately following cartilage and bone injury, and leads to tissue residing specific cell death, cartilage degeneration, bone erosion, and ultimately post-traumatic musculoskeletal degeneration. Herein, we would like to introduce a novel concept for bone and cartilage related defects treatment based on artificial transfer of exogeneous functional mitochondria (AMT). Particularly, we believe that because mitochondrial failure critically contributes to degenerative disorders onset and progression, replacing malfunctioning mitochondria with their healthy and functional counterparts can represent a novel, and effective therapeutic solution for the management of bone and cartilage related degenerative diseases. Artificial mitochondrial transfer (AMT) may reverse the failed metabolic status of musculoskeletal tissues cells and reduce bone and cartilage tissues defects by restoring mitochondrial bioenergetics.

Abstract
Cancer metabolism, including in mitochondria, is a disease hallmark and therapeutic target, but its regulation is poorly understood. Here, we show that many human tumors have heterogeneous and often reduced levels of Mic60, or Mitofilin, an essential scaffold of mitochondrial structure. Despite a catastrophic collapse of mitochondrial integrity, loss of bioenergetics, and oxidative damage, tumors with Mic60 depletion slow down cell proliferation, evade cell death, and activate a nuclear gene expression program of innate immunity and cytokine/chemokine signaling. In turn, this induces epithelial-mesenchymal transition (EMT), activates tumor cell movements through exaggerated mitochondrial dynamics, and promotes metastatic dissemination in vivo. In a small-molecule drug screen, compensatory activation of stress response (GCN2) and survival (Akt) signaling maintains the viability of Mic60-low tumors and provides a selective therapeutic vulnerability. These data demonstrate that acutely damaged, "ghost" mitochondria drive tumor progression and expose an actionable therapeutic target in metastasis-prone cancers.

Abstract
The aim of this study was to verify the role of Silent Information Regulator 7 (SIRT7) in improving the repair mechanism of bone marrow mesenchymal stem cells (BMMSCs) and the expression of microribonucleic acid (miRNA). Human BMMSCs were extracted from patients with femoral fractures, and the proliferation activity of human BMMSCs before and after knockout SIRT7 and the expression levels of bone-related genes and proteins were compared. Thirty-two 8-week-old male Sprague-Dawley (SD) rats were randomly divided into a blank group, a chitosan scaffold group, a control group, and a silence information regulator knockout group 7 (n = 8). In addition to the blank group, the chitosan scaffold, the green fluorescent protein (GFP) transfected stem cell composite chitosan scaffold, and the SIRT7 knockout stem cell composite chitosan scaffold were implanted in the other three groups, respectively. The X-rays and small animal in vivo three-dimensional tomography (Micro-CT) were adopted to quantitatively analyze the volume fraction, the number of trabeculae, and the connection density. Compared with the other three groups, the bone defect was formed more in the medullary mesenchymal stem cell knockout group, and the bone volume fraction, number of trabeculae and connection density were significantly increased (P < 0.05). MiR-98-5p can significantly promote the formation of bone molecules and bone structure in rats (P < 0.05). Human BMMSCs combined with chitosan scaffold can accelerate the repair of tibial defects. MiR-98-5p targeting and regulating bone formation gene (CKIP-1) could significantly improve the process of osteogenesis in rats.

Abstract
Background As common progenitor cells of osteoblasts and adipocytes, bone marrow mesenchymal (stromal) stem cells (BMSCs) play key roles in bone homeostasis, tissue regeneration, and global energy homeostasis; however, the intrinsic mechanism of BMSC differentiation is not well understood. Plasticity in energy metabolism allows BMSCs to match the divergent demands of osteo-adipogenic differentiation. Targeting BMSC metabolic pathways may provide a novel therapeutic perspective for BMSC differentiation unbalance related diseases. Scope of review This review covers the recent studies of glucose, fatty acids, and amino acids metabolism fuel the BMSC differentiation. We also discuss recent findings about energy metabolism in BMSC differentiation. Major conclusions Glucose, fatty acids, and amino acids metabolism provide energy to fuel BMSC differentiation. Moreover, some well-known regulators including environmental stress, hormone drugs, and biological and pathological factors may also influence BMSC differentiation by altering metabolism. This offers insight to the significance of metabolism on BMSC fate determination and provides the possibility of treating diseases related to BMSC differentiation, such as obesity and osteoporosis, from a metabolic perspective.

Abstract
Resveratrol (RES) is a novel dietary phenol compound derived from plants and has been studied extensively for its health benefit and medical potential including osteoporosis. The purpose of this study is to investigate the role of resveratrol in osteoporosis in vivo and in vitro and explore the mechanism of osteogenic differentiation of BMSCs. RT-qPCR, ELISA, and Western blot were used to measure the expression level of miR-193a, SIRT7, and osteogenic markers proteins. The interaction between miR-193a and SIRT7 was validated by dual-luciferase reporter assay. Moreover, MTT assay was conducted to detect cell viability. Alizarin red s staining was used to examine bone formation and calcium deposits. The ovariectomized rat model was set up successfully and HE staining was used to examine femoral trabeculae tissue. Our results showed that miR-193a was overexpressed, while SIRT7 was downregulated in osteoporosis. RES suppressed miR-193a to promote osteogenic differentiation. Mechanically, miR-193a targeted and negative regulated SIRT7. Additionally, it was confirmed that SIRT7 promoted osteogenic differentiation of BMSCs through NF-κB signaling pathway. Further study indicated that RES exerted its beneficial function through miR-193a/SIRT7-mediated NF-κB signaling to alleviate osteoporosis in vivo. Our research suggested that the RES-modulated miR-193a inhibition is responsible for the activation of SIRT7/NF-κB signaling pathway in the process of osteogenic differentiation, providing a novel insight into diagnosis and treatment of osteoporosis.

Abstract
In this research, resveratrol (RSV)-loaded scaffolds have been prepared to control the release of resveratrol and used to delay hepatic stellate cell (HSC) senescence in vitro. The functional carboxyl group-COOH is first introduced to the surface of poly(ε-caprolactone/d,l-lactide) (P(CL-DLLA)) under the coadministration of ultra-violet (UV) treatment and photo initiator and then resveratrol are conjugated onto the surface of the modified scaffolds through esterification. The characterization of the structure of RSV-AA-P(CL-DLLA) shows that resveratrol has been successfully conjugated onto the modified surface. Cell growth exhibits a higher level of cell viability and much more obvious agglomeration on the surface of the synthetic RSV-AA-P(CL-DLLA). Meanwhile the activity of senescence-associated β-galactosidase (SA-β-gal) and reactive oxygen species (ROS) is downgulated for cells on RSV-AA-P(CL-DLLA), which suggests that cell senescence is delayed on RSV-AA-P(CL-DLLA). And then it is attested that cells have a lower level of p53 but SIRT1 expression is upregulated on RSV-AA-P(CL-DLLA), which might be related to resveratrol release from RSV-AA-P(CL-DLLA). It also suggested cell senescence on RSV-AA-P(CL-DLLA) has been regulated by p53 and the SIRT1 signaling pathway. In all, the present study shows that RSV-AA-P(CL-DLLA) can be successfully prepared to promote cell growth and delay cell senescence and could be used for cell-based therapy in tissue engineering.

Abstract
Glucocorticoid-induced osteonecrosis of the femoral head (GIONFH) is a serious complication after long-term or excess administration of clinical glucocorticoids intervention, and the pathogenic mechanisms underlying have not been clarified yet. Oxidative stress is considered as a major cause of bone homeostasis disorder. This study is aimed to explore the potential relevance between SIRT3 and GIONFH, as well as the effect of resveratrol, which has been reported for its role in SIRT3 activation, on dexamethasone-induced oxidative stress and mitochondrial compromise in bone marrow stem cells (BMSCs). In this study, our data showed that SIRT3 level was declined in GIONFH rat femoral head, corresponding to a resultant decrease of SIRT3 expression in dexamethasone-treated BMSCs in vitro. We also found that dexamethasone could result in oxidative injury in BMSCs, and resveratrol treatment reduced this deleterious effect via a SIRT3-dependent manner. Moreover, our results demonstrated that rewarding effect of resveratrol on BMSCs osteogenic differentiation was via activation of AMPK/PGC-1α/SIRT3 axis. Meanwhile, resveratrol administration prevented the occurrence of GIONFH, enhanced SIRT3 expression and reduced oxidative level in GIONFH model rats. Therefore, our study provides basic evidence that SIRT3 may be a promising therapeutic target for GIONFH treatment and resveratrol could be an ideal agent for clinical uses.

Abstract
Resveratrol (RSV) could promote osteogenic activity, but its clinical application has been hampered in view of its poor bioavailability. Therefore, it is desirable to identify with certainty the molecular target of its bone mass boosting function, which is crucial to the design of an effective therapeutic strategy for the optimal treatment of osteoporosis. Emerging evidence has indicated that GATA-1, an important transcription factor in megakaryocyte and erythrocyte differentiation, can directly activate autophagy in erythrocytes, alluding to its impact on bone metabolism. In light of this, we sought to determine whether GATA-1 would be a putative target by which RSV would act on osteoblast proliferation and, if so, to explore the underlying mechanism involved in the process. We examined the cell viability, colony formation, cell cyclin expression, autophagy level, and the expression levels of GATA-1 and adenosine 5'-monophosphate (AMP)-activated protein kinase α (AMPKα) in osteoblastic cell strain MC3T3-E1. The results showed that RSV promoted the proliferation process in MC3T3-E1 coupled with increased expression of GATA-1 and phosphorylated AMPKα and activated autophagy. When GATA-1 was interfered with siRNA, both autophagy and proliferation were decreased. Administration of the agonist of phosphorylated AMPKα1 (Thr172) promoted the translocation of GATA-1 into the nucleus. Based on the above results, we concluded that RSV induces the proliferation of MC3T3-E1 by increasing GATA-1 expression, which thence activates autophagy; and of note, AMPKα is one of the upstream regulators of GATA-1.

Abstract
Exosomes (exo) derived from bone marrow mesenchymal stem cells (BMSCs) are known to promote cell growth through delivering multiple kinds of bioactive molecule including microRNAs (miR-NAs). This study aimed to explore the mechanism underlying miR-204 secreted by exo interacting oxidative
damage of cardiac stem cell (CSCs). Exosomes were extracted from BMSCs (BMSC-exo) and characterized by immunofluorescence and electron microscope, while BMSC-exo were internalized by CSCs. ARS and ALP staining confirmed the mineralization of BMSCs and osteogenic and adipogenic differentiation
of BMSCs. Then BMSCs were cultured in ordinary culture medium (OM) and normal medium. RT-qPCR identified miR-204 level in BMSCs disposed by OM was about five times as that of controls. miR-204 was up-regulated in the osteogenic differentiation of CSCs. Functional experiment revealed up-regulation
of miR-204 inhibited the BMSC adipogenic differentiation with decreased ROS and MDA expression and elevated SOD level in the CSCs. Treatment with BMSC-exos or miR-204 up-regulation alleviated oxidative damage of CSCs. Collectively, miR-204 attenuates the oxidative damage of CSCs through regulating
BMSC adipogenic and osteogenic differentiation.

Abstract
Osteoporosis is an age-related bone disease, characterized by rapid boneloss, decreased bone mineral density (BMD), and consequent risk of fractures. The most prevalent form of clinically significant osteoporosis involves various inflammatory conditions, especially age-dependent osteoporosis and postmenopausal osteoporosis. Tumor necrosis factor-α (TNF-α), a pro-inflammatory cytokine, plays a critical role in the development of inflammatory, which also plays an important role in bone formation and bone loss during osteoporosis. In this report, we examined the effect of TNF-α on osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) and its modulation by resveratrol (Res). We found that TNF-α can upregulate inflammatory cytokines, Il-6, Mmp-9, and Il-1β, and establish an inflammatory environment. High inflammatory cytokine expression significantly inhibited osteogenic differentiation of BMSCs by overactivating upstream Hippo kinases and decreasing the nuclear Yes-associated protein (YAP) signals. With Res treatment, decreasing inflammatory cytokine expression normalized Hippo/YAP signaling and effectively rescued YAP-mediated osteogenesis. Thus, through these studies, we present a mechanism by which TNF-α can affect BMSCs osteogenesis through modulation of Hippo/YAP signaling.

Abstract
Bone marrow mesenchymal stem cells (BMSCs) have self-renewal potential. Sirt1 regulates cell differentiation and apoptosis. However, Sirt1’s effect on BMSCs osteogenic/adipogenic differentiation has not been fully elucidated. SD rats were randomly divided into Osteoporosis (OP)
group and sham operation group. OP rat BMSCs were isolated and assigned into control group, NC group and Sirt1 siRNA group followed by analysis of Sirt1 level by Real-time PCR, cell proliferation by MTT assay, expression of OC, OPN and FABP4 level by real time PCR, and β-Catenin/TCF1/Runx2
protein expression by Western blot. In OP group, Sirt1 expression was significantly increased and BMSCs proliferation was decreased along with reduced OC and OPN mRNA expression, increased FABP4 expression and reduced β-Catenin/TCF1/Runx2 expression compared with sham operation
group (P < 0.05). In Sirt1 siRNA group, Sirt1 expression was significantly reduced, BMSCs proliferation was increased, OC and OPN mRNA expression was increased, FABP4 expression was decreased, and β-Catenin/TCF1/Runx2 expression was increased compared to OP group (P
< 0.05). Sirt1 is increased in osteoporosis. Down-regulating Sirt1 in osteoporotic BMSCs can regulate β-Catenin/TCF1/Runx2 signaling and promote BMSCs osteogenic differentiation and inhibit adipogenic differentiation.

Abstract
Bone-forming cells build mineralized microstructure and couple with bone-resorbing cells, harmonizing bone mineral acquisition, and remodeling to maintain bone mass homeostasis. Mitochondrial glycolysis and oxidative phosphorylation pathways together with ROS generation meet the energy requirement for bone-forming cell growth and differentiation, respectively. Moderate mechanical stimulations, such as weight loading, physical activity, ultrasound, vibration, and electromagnetic field stimulation, etc., are advantageous to bone-forming cell activity, promoting bone anabolism to compromise osteoporosis development. A plethora of molecules, including ion channels, integrins, focal adhesion kinases, and myokines, are mechanosensitive and transduce mechanical stimuli into intercellular signaling, regulating growth, mineralized extracellular matrix biosynthesis, and resorption. Mechanical stimulation changes mitochondrial respiration, biogenesis, dynamics, calcium influx, and redox, whereas mechanical disuse induces mitochondrial dysfunction and oxidative stress, which aggravates bone-forming cell apoptosis, senescence, and dysfunction. The control of the mitochondrial biogenesis activator PGC-1α by NAD+-dependent deacetylase sirtuins or myokine FNDC/irisin or repression of oxidative stress by mitochondrial antioxidant Nrf2 modulates the biophysical stimulation for the promotion of bone integrity. This review sheds light onto the roles of mechanosensitive signaling, mitochondrial dynamics, and antioxidants in mediating the anabolic effects of biophysical stimulation to bone tissue and highlights the remedial potential of mitochondrial biogenesis regulators for osteoporosis.

Abstract
Critical-sized bone defects caused by traumatic fractures, tumour resection and congenital malformation are unlikely to heal spontaneously. Bone tissue engineering is a promising strategy aimed at developing in vitro replacements for bone transplantation and overcoming the limitations of natural bone grafts. In this study, we developed an innovative bone engineering scaffold based on gelatin methacrylate (GelMA) hydrogel, obtained via a two-step procedure: first, solid lipid nanoparticles (SLNs) were loaded with resveratrol (Res), a drug that can promote osteogenic differentiation and bone formation; these particles were then encapsulated at different concentrations (0.01%, 0.02%, 0.04% and 0.08%) in GelMA to obtain the final Res-SLNs/GelMA scaffolds. The effects of these scaffolds on osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) and bone regeneration in rat cranial defects were evaluated using various characterization assays. Our in vitro and in vivo investigations demonstrated that the different Res-SLNs/GelMA scaffolds improved the osteogenic differentiation of BMSCs, with the ideally slow and steady release of Res; the optimal scaffold was 0.02 Res-SLNs/GelMA. Therefore, the 0.02 Res-SLNs/GelMA hydrogel is an appropriate release system for Res with good biocompatibility, osteoconduction and osteoinduction, thereby showing potential for application in bone tissue engineering.

Abstract
Non-healing wounds have demonstrated aberrant regulation of several growth factors, thus using exogenous growth factors and cytokines in the clinical setting may improve the outcomes of non-healing wounds. Mesenchymal stem cells (MSCs) are the source of growth factors that show beneficial effect in promoting impaired wound healing. Certain culture condition should be developed to stimulate growth factor secretion from stem cell. Resveratrol, a small molecule found to increase MSCs therapeutic effectiveness. This study aims to investigate the effect of RV on secretion of wound healing related growth factors. We isolated and characterised MSCs from wharton's jelly (WJ), amniotic membrane (AM), and adipose tissue. We treated MSCs with serum deprived medium (SDM) supplemented with RV at 0.1 µM, 0.5 µM, 0.8 µM concentration. Our study revealed that RV at 0.1 µM was more effective to increase cell proliferation rate. Resveratrol at 0.1 µM promoted EGF, HGF, PDGF, and TGF-β1 secretion from MSCs. AD-MSCs showed the greatest response to RV stimulation in the term of cell proliferation and growth factors secretion. As conclusion, RV can facilitate cell proliferation and wound healing related growth factors secretion at dosage dependent manner.

Abstract
Osteoporosis is a chronic age-related disease. During aging, bone marrow-derived mesenchymal stem cells (BMSCs) display increased adipogenic, along with decreased osteogenic, differentiation capacity. The aim of the present study was to investigate the effect of calcitonin gene-related peptide (CGRP) on the osteogenic and adipogenic differentiation potential of BMSC-derived osteoblasts. Here, we found that the level of CGRP was markedly lower in bone marrow supernatant from aged mice compared with that in young mice. In vitro experiments indicated that CGRP promoted the osteogenic differentiation of BMSCs while inhibiting their adipogenic differentiation. Compared with vehicle-treated controls, aged mice treated with CGRP showed a substantial promotion of bone formation and a reduction in fat accumulation in the bone marrow. Similarly, we found that CGRP could significantly enhance bone formation in ovariectomized (OVX) mice in vivo. Together, our results suggested that CGRP may be a key regulator of the age-related switch between osteogenesis and adipogenesis in BMSCs and may represent a potential therapeutic strategy for the treatment of age-related bone loss.

Abstract
Collagen membranes produced in vitro with different degrees of intrafibrillar mineralization are potentially useful for guided bone regeneration (GBR). However, highly-mineralized collagen membranes are brittle and difficult for clinical manipulation. The present study aimed at developing an intrafibrillar self-mineralization strategy for GBR membrane by covalently conjugating high-molecular weight polyacrylic acid (HPAA) on Bio-Gide® membranes (BG). The properties of the self-mineralizable membranes (HBG) and their potential to induce bone regeneration were investigated. The HBG underwent the progressive intrafibrillar mineralization as well as the increase in stiffness after immersed in supersaturated calcium phosphate solution, osteogenic medium, or after being implanted into a murine calvarial bone defect. The HBG promoted in-situ bone regeneration via stimulating osteogenic differentiation of mesenchymal stromal cells (MSCs). Hippo signaling was inhibited when MSCs were cultured on the self-mineralized HBG, and in HBG-promoted MSC osteogenesis during in-situ bone regeneration. This resulted in translocation of the transcription co-activators Yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ) into the nucleus to induce transcription of genes promoting osteogenic differentiation of MSCs. Taken together, these findings indicated that HBG possessed the ability to self-mineralize in situ via intrafibrillar mineralization. The increase in stiffness of the extracellular matrix expedited in-situ bone regeneration by inactivating the Hippo-YAP/TAZ signaling cascade. STATEMENT OF SIGNIFICANCE: Guided bone regeneration (GBR) membranes made of naturally derived collagen have been widely used in the bone defect restoration. However, application of collagen GBR membranes run into the bottleneck with the challenges like insufficient stress strength, relatively poor dimensional stability and unsatisfactory osteoinductivity. This study develops a modified GBR membrane that can undergo progressive self-mineralization and matrix stiffening in situ. Increase in extracellular matrix stiffness provides the mechanical cues required for MSCs differentiation and expedites in-situ bone regeneration by inactivating the Hippo-YAP/TAZ signaling cascade.

Abstract
Bone marrow mesenchymal stem cells (BMSCs) present reduced proliferation under high glucose condition. Liver kinase B1 (LKB1) can maintain the homeostasis of hematopoietic stem cells. However, whether LKB1 regulates BMSCs osteogenic/adipogenic differentiation under high glucose is unclear.
Rat BMSCs were isolated and separated into control group, high glucose group, and LKB1 group (BMSCs were transfected with pc-DNA 3.1-LKB1 plasmid under high glucose condition) followed by analysis of LKB1 expression by Real time PCR and Western blot, osteocalcin, type I collagen, RUNX2 and
OPN mRNA level by real-time PCR, FABP4 and PPARγ2 level by western blot. In high glucose group, LKB1 expression was significantly decreased, with reduced expression of osteocalcin, type I collagen, RUNX2 and OPN mRNA and elevated FABP4 and PPARγ2 level compared to control group
(P < 0.05). Transfection of LKB1 plasmid reduced LKB1 expression, upregulated osteocalcin, type I collagen, RUNX2 and OPN mRNA and downregulated FABP4 and PPARγ2. Compared with the high glucose group, there was a statistical difference (P <0.05). High glucose can
inhibit LKB1 expression and BMSCs osteogenic differentiation, and promote adipogenic differentiation. Upregulating LKB1 expression can promote BMSCs osteogenic differentiation.

Abstract
Bone marrow stromal stem cells (BMSCs) can be used to treat bone defects but BMSCs are damaged under oxidative stress. The neuropeptide substance P (SP) involves various cellular activities. However, SP’s role in BMSCs differentiation under oxidative stress is unknown. Rat BMSCs
were isolated and assigned into control group; oxidative stress group treated with 200 μM H2O2; and SP group, in which 10 mM SP was added under oxidative stress followed by analysis of SP secretion by ELISA, cell proliferation by MTT method, Caspase3 activity, Bax
and Bcl-2 level by Real time PCR, ALP activity ROS and SOD content as well as NF-κB level by Western blot. Under oxidative stress, SP secretion was significantly decreased, BMSCs proliferation was inhibited, Caspase3 activity and Bax expression increased, Bcl-2 and ALP activity was decreased
along with increased ROS activity and NF-κB level and reduced SOD activity (P <0.05), adding SP to BMSCs under oxidative stress can significantly promote SP secretion and cell proliferation, reduce Caspase3 activity and Bax expression, increase Bcl-2 expression and ALP activity,
decreased ROS activity and NF-κB level, and elevated SOD activity (P <0.05). SP secretion from BMSCs cells was reduced under oxidative stress. Up-regulation of SP in BMSCs cells under oxidative stress can inhibit BMSCs apoptosis and promote cell proliferation and osteogenesis
by regulating NF-κB.

Abstract
Human bone marrow mesenchymal stem cells (BMSCs) differentiation into special cell types is affected by inflammation. Melatonin has various effects such as anti-oxidation and immune regulation. However, melatonin’s effect on BMSCs osteogenic differentiation during inflammation
has not been elucidated. Rat BMSCs were isolated and assigned into control group, inflammation group (1 μg/ml lipopolysaccharide, LPS) and melatonin group (100 μM melatonin was added to LPSstimulated BMSCs cells) followed by analysis of BMSCs proliferation by MTT assay, Caspase 3 and
ALP activity, expression of Runx2 and OP by Real time PCR, ROS content and SOD activity, TNF-α and IL-1β secretion by ELISA and mTOR/PI3K/AKT signaling protein level by Western blot. LPS action on BMSCs significantly inhibits BMSCs proliferation, promotes Caspase 3 activity, inhibits
ALP activity, decreases Runx2 and OP expression and SOD activity, increases ROS content and TNF-α and IL-1β secretion as well as reduced mTOR and p-PI3K level (P <0.05). Melatonin addition significantly reversed the above changes (P <0.05). Melatonin can regulate oxidative
stress, inhibit inflammation, and promote BMSCs proliferation and osteogenic differentiation in inflammatory environment by activating mTOR/PI3K/AKT signaling pathway.

Abstract
Reactive oxygen species (ROS) have emerged as key players in regulating the fate and function of stem cells from both non-hematopoietic and hematopoietic lineages in bone marrow, and thus affect the osteoblastogenesis-osteoclastogenesis balance and bone homeostasis. Accumulating evidence has linked ROS and associated oxidative stress with the progression of bone disorders, and ROS-based therapeutic strategies have appeared to achieve favorable outcomes in bone. We review current knowledge of the multifactorial roles and mechanisms of ROS as a target in bone pathology. In addition, we discuss emerging ROS-based therapeutic strategies that show potential for bone therapy. Finally, we highlight the opportunities and challenges facing ROS-targeted stem cell therapeutics for improving bone health.

Abstract
Bone marrow mesenchymal stem cells (BMSCs) are a potential source of osteoblasts and have been widely used in clinical therapies due to their pluripotency. Recent publications have found that resveratrol (RSVL) played a crucial role in the proliferation and differentiation of BMSCs; however, the underlying molecular mechanism of RSVL-induced BMSCs osteogenic differentiation needs to be fully elucidated. The objective of this study was to explore functions of miRNAs in the RSVL-treated BMSCs and its effects on the differentiation potentials of BMSCs. The findings demonstrated that RSVL enhanced the osteogenesis and suppressed the adipogenesis of BMSCs in a dose-dependent manner. Besides, a novel regulatory axis containing miR-320c, and its target Runx2 was found during the differentiation process of BMSCs under RSVL treatment. Increase of miR-320c reduced the osteogenic potential of BMSCs, while knockdown of miR-320c played a positive role in the osteogenesis of BMSCs. In contrast, overexpression of miR-320c accelerated the adipogenic differentiation, while knockdown of miR-320c restrained the adipogenic differentiation of BMSCs. The results confirmed that Runx2 might be the direct target of miR-320c in RSVL-promoted osteogenic differentiation of BMSCs. This study revealed that RSVL might be used for the treatment of bone loss related diseases and miR-320c could be regarded as a novel and potential target to regulate the biological functions of BMSCs.

Semaphorin3B Promotes Proliferation and Osteogenic Differentiation of Bone Marrow Mesenchymal Stem Cells in a High-Glucose Microenvironment. Stem Cells Int 2021; 2021:6637176.

Abstract
Bone marrow mesenchymal stem cells (BMSCs) play an essential role in osteogenesis and bone metabolism and have already been recognized as one of the most popular seed cells for bone tissue engineering for bone diseases. However, high-glucose (HG) conditions in type 2 diabetes mellitus (T2DM) exert deleterious effects on BMSC proliferation and osteogenic differentiation. Semaphorin 3B (Sema3B) increases osteoblast differentiation in bone metabolism. Here, we determined the role of Sema3B in the proliferation and osteogenic differentiation of BMSCs in the HG microenvironment. The HG microenvironment decreased Sema3B expression in BMSCs. Moreover, HG inhibited BMSC proliferation. Furthermore, HG inhibited osteogenic differentiation in BMSCs by decreasing the expression of bone formation markers, alkaline phosphatase (ALP) activity, and mineralization. However, the administration of recombinant Sema3B reversed all of these effects. Moreover, our study found that Sema3B could activate the Akt pathway in BMSCs. Sema3B rescues defects in BMSC proliferation and osteogenic differentiation in the HG microenvironment by activating the Akt pathway. These effects were significantly reduced by treatment with an Akt inhibitor. Together, these findings demonstrate that Sema3B promotes the proliferation and osteogenic differentiation of BMSCs via the Akt pathway under HG conditions. Our study provides new insights into the potential ability of Sema3B to ameliorate BMSC proliferation and osteogenic differentiation in an HG microenvironment.

Abstract
Ossification of ligaments (OL) and osteoporosis (OP) are multifactorial disorders without definitive clinical biomarkers. Long non-coding RNAs (lncRNAs) are known to involve in regulating pathogenesis. Here, we have identified a preosteoblast-enriched lnc-Evf2 that was overexpressed in ossified ligamentum flavum (OLF) and down-expressed in OP. lnc-Evf2 is gradually upregulated during osteogenic induction, correlating with the enhanced expression of osteogenic marker genes and matrix mineralization. Moreover, knockdown of lnc-Evf2 significantly inhibits the expression of osteogenic differentiation markers and delays the osteoblastic mineralization process, indicating that this molecule is involved in osteogenesis. Mechanistically, we demonstrated that silencing of lnc-Evf2 decreases the protein level but not the mRNA levels of Notch2, Notch3, and Hes1, all of which correlate with osteogenesis. Taken together, our data demonstrate that lnc-Evf2 promotes osteogenic differentiation and bone formation through the Notch signaling, revealing that lnc-Evf2 may serve as a novel potential clinical target of OL and OP.

Abstract
Background This study aimed to explore the effect of KAT6A on the decreased stemness of aging bone marrow-derived mesenchymal stem cells (BMSCs) and its potential mechanism. Methods The acetylation level and KAT6A expression of BMSCs from the young (YBMSCs) and the old (OBMSCs) were examined. Gain- and loss-of-function experiments were performed to determine the effect of KAT6A on BMSC proliferation, colony formation, and osteogenic differentiation. The effect of KAT6A on Nrf2/ARE signaling pathway was investigated after KAT6A inhibition in YBMSCs or overexpression in OBMSCs, and the role of Nrf2/ARE signaling pathway on stemness was examined by investigating proliferation, colony formation, and osteogenic differentiation. Further in vivo study was performed to explore osteogenesis ability of OBMSCs after modulation of KAT6A and Nrf2/ARE pathway through cell sheet technology. Results The acetylation level and KAT6A expression of OBMSCs were decreased, and KAT6A downregulation resulted in decreased proliferation, colony formation, and osteogenic differentiation of OBMSCs. Mechanically, KAT6A was found to regulate Nrf2/ARE signaling pathway and inhibit ROS accumulation in OBMSCs, thus promoting proliferation, colony formation, and osteogenic differentiation of OBMSCs. Further study demonstrated that KAT6A could promote osteogenesis of OBMSCs by regulating Nrf2/ARE signaling pathway. Conclusions Downregulation of KAT6A resulted in the decreased stemness of OBMSCs by inhibiting the Nrf2/ARE signaling pathway. Graphical abstract KAT6A was downregulated in aging bone marrow-derived mesenchymal stem cells (BMSCs), and downregulation of KAT6A resulted in Nrf2/ARE signaling pathway inhibition and ROS accumulation, thus leading to decreased stemness of aging BMSCs.

Abstract
Osteoarthritis (OA) pathogenesis involves inflammation, age, weight and other factors. Integrin-linked kinase (ILK) regulates cell apoptosis, metastasis, and growth. However, whether ILK affects bone formation of bone marrow mesenchymal stem cells in an inflammatory environment has
not been elucidated. Rat BMSCs were isolated and assigned into control group, inflammation group (lipopolysaccharide was added to cells); and si-ILK group (ILK siRNA was transfected into the inflammation group BMSCs) followed by analysis of cell proliferation by MTT assay, expression of ILK,
Runx2 and OP by real time PCR, ALp activity, TNF-α and IL-6 secretion by ELISA and MAPK/AKT signaling protein expression by western blot. Compared to control, ILK in BMSCs cells in inflammatory environment was significantly upregulated, resulting in inhibition of cell proliferation,
decreased ALP activity, reduced expression of osteogenic genes Runx2 and OP, increased secretion of TNF-α and IL-6, and downregulated p-AKT (P < 0.05); transfection of ILK siRNA down-regulated ILK in inflammatory environment BMSCs, which significantly increased BMSCs
cell proliferation, increased ALP activity and expression of Runx2 and OP, decreased TNF-α and IL-6 secretion and increased p-AKT expression (P < 0.05). ILK expression is increased in BMSCs in an inflammatory environment. Down-regulation of ILK in BMSCs cells in an inflammatory
environment can regulate MAPK/AKT signaling, inhibit inflammatory factors secretion, thereby promoting BMSCs proliferation and osteogenesis differentiation.

Abstract
The rapid aging of worldwide populations had led to epidemic increases in the incidence of osteoporosis (OP), but while treatments are available, high cost, adverse effects, and poor compliance continue to be significant problems. Naturally occurring plant-based compounds including phytoestrogens can be good and safe candidates to treat OP, but screening for osteogenic capacity has been difficult to achieve, largely due to the requirement of using primary osteoblasts or mesenchymal stem cells (MSCs), the progenitors of osteoblasts, to conduct time-consuming in vitro and in vivo osteogenic assay. Taking advantage of MSC osteogenic capacity and utilizing a promoter reporter assay for Runx2, the master osteogenesis transcription factor, we developed a rapid in vitro screening platform to screen osteogenic small molecules including natural plant-based compounds. We screened eight plant-derived compounds from different families including flavonoids, polyphenolic compounds, alkaloids, and isothiocyanates for osteogenic capacity using the human RUNX2-promoter luciferase reporter (hRUNX2-luc) transduced into the mouse MSC line, C3H10T1/2, with daidzein-a well-studied osteogenic phytoestrogen-as a positive control. Classical in vitro and in vivo osteogenesis assays were performed using primary murine and human bone marrow MSCs (BMMSCs) to validate the accuracy of this rapid screening platform. Using the MSC/hRUNX2-luc screening platform, we were able not only to shorten the selection process for osteogenic compounds from 3∼4 weeks to just a few days but also simultaneously perform comparisons between multiple compounds to assess relative osteogenic potency. Predictive analyses revealed nearly absolute correlation of the MSC/hRUNX2-luc reporter platform to the in vitro classical functional assay of mineralization using murine BMMSCs. Validation using human BMMSCs with in vitro mineralization and in vivo osteogenesis assays also demonstrated nearly absolute correlation to the MSC/hRUNX2-luc reporter results. Our findings therefore demonstrate that the MSC/hRUNX2 reporter platform can accurately, rapidly, and robustly screen for candidate osteogenic compounds and thus be relevant for therapeutic application in OP.

Abstract
Diabetic osteoporosis (DOP) is attributed to the aberrant physiological function of bone marrow mesenchymal stem cells (BMSCs) under high glucose (HG) environment. MicroRNAs (miRNAs) are involved in the pathological processes of DOP. We aimed to explore the underlying mechanism of miRNA in DOP. BMSCs were cultured in osteogenic medium with HG to induce osteogenic differentiation, and the interaction between miR-493-5p and ZEB2 was assessed by luciferase assay. Herein, we found miR-493-5p is gradually reduced during osteogenic differentiation in BMSCs. HG treatment inhibits osteogenic differentiation and induces an up-regulation of miR-493-5p leading to reduced level of its downstream target ZEB2. Inhibition of miR-493-5p attenuates HG-induced osteogenic differentiation defects by upregulation of ZEB2. Mechanistically, miR-493-5p/ZEB2 signalling mediates HG-inhibited osteogenic differentiation by inactivation of Wnt/β-catenin signalling. More importantly, knockdown of miR-493-5p therapeutically alleviated the DOP condition in mice. HG prevents BMSCs osteogenic differentiation via up-regulation of miR-493-5p, which results in reduced level of ZEB2 by directly targeting its 3'-untranslated region of mRNA. Thus, miR-493-5p/ZEB2 is a potential therapeutic target and provides novel strategy for the treatment and management of DOP.

Abstract
Mesenchymal stromal cell (MSC) metabolism plays a crucial role in the surrounding microenvironment in both normal physiology and pathological conditions. While MSCs predominantly utilize glycolysis in their native hypoxic niche within the bone marrow, new evidence reveals the importance of upregulation in mitochondrial activity in MSC function and differentiation. Mitochondria and mitochondrial regulators such as sirtuins play key roles in MSC homeostasis and differentiation into mature lineages of the bone and hematopoietic niche, including osteoblasts and adipocytes. The metabolic state of MSCs represents a fine balance between the intrinsic needs of the cellular state and constraints imposed by extrinsic conditions. In the context of injury and inflammation, MSCs respond to reactive oxygen species (ROS) and damage-associated molecular patterns (DAMPs), such as damaged mitochondria and mitochondrial products, by donation of their mitochondria to injured cells. Through intercellular mitochondria trafficking, modulation of ROS, and modification of nutrient utilization, endogenous MSCs and MSC therapies are believed to exert protective effects by regulation of cellular metabolism in injured tissues. Similarly, these same mechanisms can be hijacked in malignancy whereby transfer of mitochondria and/or mitochondrial DNA (mtDNA) to cancer cells increases mitochondrial content and enhances oxidative phosphorylation (OXPHOS) to favor proliferation and invasion. The role of MSCs in tumor initiation, growth, and resistance to treatment is debated, but their ability to modify cancer cell metabolism and the metabolic environment suggests that MSCs are centrally poised to alter malignancy. In this review, we describe emerging evidence for adaptations in MSC bioenergetics that orchestrate developmental fate decisions and contribute to cancer progression. We discuss evidence and potential strategies for therapeutic targeting of MSC mitochondria in regenerative medicine and tissue repair. Lastly, we highlight recent progress in understanding the contribution of MSCs to metabolic reprogramming of malignancies and how these alterations can promote immunosuppression and chemoresistance. Better understanding the role of metabolic reprogramming by MSCs in tissue repair and cancer progression promises to broaden treatment options in regenerative medicine and clinical oncology.

A novel negative regulatory mechanism of Smurf2 in BMP/Smad signaling in bone. Bone Res 2020; 8:41. [PMID: 33298874 PMCID: PMC7680794 DOI: 10.1038/s41413-020-00115-z] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2020] [Revised: 08/08/2020] [Accepted: 08/18/2020] [Indexed: 12/19/2022] Open
Abstract
Transforming growth factor-β (TGF-β) and bone morphogenetic protein (BMP) play important roles in bone metabolism. Smad ubiquitination regulatory factors (Smurfs) regulate TGF-β/BMP signaling via ubiquitination, resulting in degradation of signaling molecules to prevent excessive activation of TGF-β/BMP signaling. Though Smurf2 has been shown to negatively regulate TGF-β/Smad signaling, its involvement in BMP/Smad signaling in bone metabolism has not been thoroughly investigated. In the present study, we sought to evaluate the role of Smurf2 in BMP/Smad signaling in bone metabolism. Absorbable collagen sponges containing 3 μg of recombinant human BMP2 (rhBMP2) were implanted in the dorsal muscle pouches of wild type (WT) and Smurf2−/− mice. The rhBMP2-induced ectopic bone in Smurf2−/− mice showed greater bone mass, higher mineral apposition and bone formation rates, and greater osteoblast numbers than the ectopic bone in WT mice. In WT mice, the ectopic bone consisted of a thin discontinuous outer cortical shell and scant inner trabecular bone. In contrast, in Smurf2−/− mice, the induced bone consisted of a thick, continuous outer cortical shell and abundant inner trabecular bone. Additionally, rhBMP2-stimulated bone marrow stromal cells (BMSCs) from Smurf2−/− mice showed increased osteogenic differentiation. Smurf2 induced the ubiquitination of Smad1/5. BMP/Smad signaling was enhanced in Smurf2−/− BMSCs stimulated with rhBMP2, and the inhibition of BMP/Smad signaling suppressed osteogenic differentiation of these BMSCs. These findings demonstrate that Smurf2 negatively regulates BMP/Smad signaling, thereby identifying a new regulatory mechanism in bone metabolism.
