Efficacy of adipose-derived stem cells and stromal vascular fraction for pain relief in Kellgren-Lawrence grade II-III knee osteoarthritis: A systematic review (2019-2024). J Orthop 2025; 70:95-106.

Abstract
Background Knee osteoarthritis (KOA) is a common degenerative condition, affecting individuals aged 40 and above. Current therapeutic options often fail to prevent disease progression and provide only short-term pain relief, leading to an increasing interest in regenerative medicine. Adipose-derived mesenchymal stem cells (ADMSCs) and stromal vascular fraction (SVF) have emerged as promising alternatives due to their potential to modulate inflammation and promote tissue repair. However, limited studies compare the efficacy of these two therapies for KOA. Methods A systematic review (2019-2024) across PubMed, CINAHL, and Embase included studies on patients aged 40+ with Grade II-III knee osteoarthritis (Kellgren-Lawrence) treated with intra-articular ADMSC and SVF injections. Inclusion criteria followed the SPIDER framework, focusing on pain relief and joint function improvement over ≥3 months, measured via VAS, KOOS, and WOMAC. MeSH terms for KOA and ADMSC/SVF therapies were used, with bias assessed via GRADE. Results Ten studies, including three randomized controlled trials and two observational studies, met the criteria, encompassing 452 patients. Results indicate that ADMSC therapies demonstrate prolonged pain relief and enhanced joint function up to 24 months post-treatment, with superior outcomes in cartilage regeneration compared to SVF. SVF provided quicker symptom relief due to its diverse cell composition but plateaued around 12 months. Both treatments had minimal adverse effects, with lipoaspiration-related symptoms being the most common. Conclusion ADMSC and SVF stem cell therapies represent promising non-surgical options for managing knee osteoarthritis (KOA) in patients over 40. ADMSC demonstrates higher efficacy in sustaining long-term pain relief and joint health, with significant potential for cartilage regeneration. The chondrogenic properties of ADMSCs make them particularly beneficial for patients younger than 62 years old. Conversely, SVF, with its heterogeneous cell composition, provides rapid paracrine effects, offering early symptom relief and broader applicability for older or obese patients, including those with a Body Mass Index (BMI) over 30.

Abstract
Osteoarthritis, a major global cause of pain and disability, is driven by the irreversible degradation of hyaline cartilage in the joints. Cartilage tissue engineering presents a promising therapeutic avenue, but success hinges on replicating the native physiological environment to guide cellular behavior and generate tissue constructs that mimic natural cartilage. Although electrical stimulation has been shown to enhance chondrogenesis and extracellular matrix production in two-dimensional (2D) cultures, the mechanisms underlying these effects remain poorly understood, particularly in three-dimensional (3D) models. Here, we report that direct scaffold-coupled electrical stimulation applied to 3D graphene foam bioscaffolds significantly enhances the mechanical properties of the resulting graphene foam-cell constructs. Using custom 3D-printed electrical stimulus chambers, we applied biphasic square impulses (20, 40, 60 mVpp at 1 kHz) for 5 min daily over 7 days. Stimulation at 60 mVpp increased the steady-state energy dissipation and equilibrium modulus by approximately 65 and 25%, respectively, as compared with unstimulated controls. 60 mVpp stimulation also yielded the highest cell density among stimulated samples. In addition, our custom chambers facilitated full submersion of the hydrophobic graphene foam in media, leading to enhanced cell attachment and integration across the scaffold surface and within its hollow branches. To assess this cellular integration, we employed colocalized confocal fluorescence microscopy and X-ray microCT imaging enabled by colloidal gold nanoparticle and fluorophore staining, which allowed visualization of cell distribution within the opaque scaffold's internal structure. These findings highlight the potential of a direct scaffold-coupled electrical stimulus to modulate the mechanical properties of engineered tissues and offer insights into the emergent behavior of cells within conductive 3D bioscaffolds.

Abstract
Premature closure of the epiphyseal plate inducing by the formation of bone bridges after epiphyseal plate injury, can lead to limb shortening and angular deformity, causing adverse effects on the growth and development of adolescents. Therefore, preventing the formation of bone bridges has become the primary task for children with epiphyseal plate fractures. In our study, a novel near-infrared (NIR)-responsive bone repair scaffold (CGCB), namely black phosphorus (BP)-loaded in-situ gel based on curdlan (CUD), β-glycerophosphate (GP) and chitosan (CS), was developed. In vitro studies confirmed that the CGCB can promote the differentiation and migration of chondrocytes and has potential cartilage repair ability. A drilled model of epiphyseal plate injury further confirmed that CGCB can promote the repair of epiphyseal plate injury and NIR irradiation combined with CGCB significantly repaired the injury site by increasing expression of Sox9 and Aggrecan. The above findings indicate that the near-infrared (NIR) responsive bone repair scaffold (CGCB) can effectively inhibit bone bridge formation, prevent early closure of the epiphyseal plate, and provide new ideas for repairing epiphyseal plate defects in children.

Bone Res 2025; 13:41.

Abstract
Clinical translation of tissue-engineered advanced therapeutic medicinal products is hindered by a lack of patient-dependent and independent in-process biological quality controls that are reflective of in vivo outcomes. Recent insights into the mechanism of native bone repair highlight a robust path dependence. Organoid-based bottom-up developmental engineering mimics this path-dependence to design personalized living implants scaffold-free, with in-build outcome predictability. Yet, adequate (noninvasive) quality metrics of engineered tissues are lacking. Moreover, insufficient insight into the role of donor variability and biological sex as influencing factors for the mechanism toward bone repair hinders the implementation of such protocols for personalized bone implants. Here, male and female bone-forming organoids were compared to non-bone-forming organoids regarding their extracellular matrix composition, transcriptome, and secreted proteome signatures to directly link in vivo outcomes to quality metrics. As a result, donor variability in bone-forming callus organoids pointed towards two distinct pathways to bone, through either a hypertrophic cartilage or a fibrocartilaginous template. The followed pathway was determined early, as a biological sex-dependent activation of distinct progenitor populations. Independent of donor or biological sex, a cartilage-to-bone transition was driven by a common panel of secreted factors that played a role in extracellular matrix remodeling, mineralization, and attraction of vasculature. Hence, the secreted proteome is a source of noninvasive biomarkers that report on biological potency and could be the missing link toward data-driven decision-making in organoid-based bone tissue engineering.

Abstract
The avascular structure and low cell migration to the damaged area due to the low number of cells do not allow spontaneous repair of the articular cartilage tissue. Therefore, functional scaffolds obtained from biomaterials are used for the regeneration of cartilage tissue. Here, we functionalized one of the self-assembling peptide (SAP) scaffolds KLD (KLDLKLDLKLDL) with short bioactive motifs, which are the α1 chain of type II collagen binding peptide WYRGRL (C1) and the triple helical collagen mimetic peptide GFOGER (C2) by direct coupling. Our goal was to develop injectable functional SAP hydrogels with proper mechanical characteristics that would improve chondrogenesis. Scanning electron microscopy (SEM) was used to observe the integration of peptide scaffold structure at the molecular level. To assure the stability of SAPs, the rheological characteristics and degradation profile of SAP hydrogels were assessed. The biochemical study of the DNA, glycosaminoglycan (GAG), and collagen content revealed that the developed bioactive SAP hydrogels greatly increased hMSCs proliferation compared with KLD scaffolds. Moreover, the addition of bioactive peptides to KLD dramatically increased the expression levels of important chondrogenic markers such as aggrecan, SOX-9, and collagen Type II as evaluated by real-time polymerase chain reaction (PCR). We showed that hMSC proliferation and chondrogenic differentiation were encouraged by the developed SAP scaffolds. Although the chondrogenic potentials of WYRGRL and GFOGER were previously investigated, no study compares the effect of the two peptides integrated into 3-D SAP hydrogels in chondrogenic differentiation. Our findings imply that these specifically created bioactive peptide scaffolds might help enhance cartilage tissue regeneration.

Abstract
In patients with acute leukemia (AL), malignant cells and therapy modify the properties of multipotent mesenchymal stromal cells (MSCs) and their descendants, reducing their ability to maintain normal hematopoiesis. The aim of this work was to elucidate the alterations in MSCs at the onset and after therapy in patients with AL. The study included MSCs obtained from the bone marrow of 78 AL patients (42 AML and 36 ALL) and healthy donors. MSC growth characteristics, gene expression pattern, proteome and secretome were studied using appropriate methods. The concentration of MSCs in the bone marrow, proliferative potential, the expression of several genes, proteomes and secretomes were altered in AL-MSCs. Stromal progenitors had been affected differently in ALL and AML patients. In remission, MSC functions remain impaired despite the absence of tumor cells and the maintenance of benign hematopoietic cells. AL causes crucial and, to a large extent, irreversible changes in bone marrow MSCs.

Abstract
Purpose To identify key molecular components within the femoroacetabular impingement hip and compare the findings between male and female patients across varying age groups. Methods All patients undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS) without hip dysplasia were included. During hip arthroscopy, performed at University of Wisconsin Health, loose articular cartilage, excess synovium, damaged labral tissue, and minimal adipose tissue were debrided only as needed for visualization and tissue repair purposes and collected. Tissue was processed and used for quantitative polymerase chain reaction (qPCR). Genes were selected for qPCR on the basis of their associated function in inflammation and/or extracellular matrix remodeling during the progression of osteoarthritis. Results A total of 91 male (M) and female (F) patients 15 to 58 years old were included in the study. qPCR results indicated that Interleukin-6 (P < .05, 95% confidence interval [CI] 0.047-0.083 F, 0.070-0.12 M) and Interleukin-8 (P = .04, 95% CI 0.059-0.10 F, 0.082-0.18 M) were significantly greater in male patients compared with female patients regardless of age, and IL6 (P = .02, 95% CI [0.026-0.070] F, [0.067-0.17] M), Interleukin-1ß (P < .01 95% CI [0.013-0.063] F, [0.073-0.25] M), and Matrix metalloproteinase-13 (P = .047, 95% CI [0.0051-0.017] F, [0.0084-0.052] M) were significantly greater in male patients younger than 20 years old compared with female patients younger than 20 years old. Conclusions In patients with FAIS, there are significant differences between male and female patients in the biomarkers present in the affected hip at the time of surgery. Male patients have greater levels of IL6 and IL8 and male patients younger than 20 years of age have greater levels of IL1β, IL6, and MMP13 compared with age-matched female patients. Clinical Relevance A better understanding of the molecular markers present during varying stages of FAIS and in patients of different ages will help characterize the pathologic process behind FAIS. This may also help define future methods of targeted treatment and prevention of disease progression.

Abstract
Ex vivo tissue engineering is an effective therapeutic approach for the treatment of severe cartilage diseases that require tissue replenishment or replacement. This strategy demands scaffolds that are durable enough for long-term cell culture to form artificial tissue. Additionally, such scaffolds must be biocompatible to prevent the transplanted matrix from taking a toll on the patient's body. From the viewpoint of structure and bio-absorbability, a β-tricalcium phosphate (β-TCP) fiber scaffold (βTFS) is expected to serve as a good scaffold for tissue engineering. However, the fragility and high solubility of β-TCP fibers make this matrix unsuitable for long-term cell culture. To solve this problem, we developed an alginate-coated β-TCP fiber scaffold (βTFS-Alg). To assess cell proliferation and differentiation in the presence of βTFS-Alg, we characterized ATDC5 cells, a chondrocyte-like cell line, when grown in this matrix. We found that alginate coated the surface of βTFS fiber and suppressed the elution of Ca2+ from β-TCP fibers. Due to the decreased solubility of βTFS-Alg compared with β-TCP, the former provided an improved scaffold for long-term cell culture. Additionally, we observed superior cell proliferation and upregulation of chondrogenesis marker genes in ATDC5 cells cultured in βTFS-Alg. These results suggest that βTFS-Alg is suitable for application in tissue culture.

Shi L, Ura K, Takagi Y. Effects of self-assembled type II collagen fibrils on the morphology and growth of pre-chondrogenic ATDC5 cells. OSTEOARTHRITIS AND CARTILAGE OPEN 2024; 6:100450. [PMID: 38444516 PMCID: PMC10914481 DOI: 10.1016/j.ocarto.2024.100450] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Accepted: 02/22/2024] [Indexed: 03/07/2024] Open
Abstract
Objective Although type II collagen could have marked potential for developing cartilage tissue engineering (CTE) scaffolds, its erratic supply and viscous nature have limited these studies, and there are no studies on the use of marine-derived type II collagen fibrils for CTE scaffold materials. In this study, we aimed to generate a fibril-based, thin-layered scaffold from marine-derived type II collagen and investigate its chondrogenic potential. Methods Time-lapse observations revealed the cell adhesion process. The Cell Counting Kit-8 (CCK-8) assay, light microscopy, and scanning electron microscopy were performed to detect proliferation and filopodium morphology. Alcian blue staining was used to show the deposition of extracellular secretions, and qRT-PCR was performed to reveal the expression levels of chondrogenesis-related genes. Results The cell adhesion speed was similar in both fibril-coated and control molecule-coated groups, but the cellular morphology, proliferation, and chondrogenesis activity differed. On fibrils, more elongated finer filopodia showed inter-cell communications, whereas the slower proliferation suggested an altered cell cycle. Extracellular secretions occurred before day 14 and continued until day 28 on fibrils, and on fibrils, the expression of the chondrogenesis-related genes Sox9 (p < 0.001), Col10a1 (p < 0.001), Acan (p < 0.001), and Col2a1 (p = 0.0049) was significantly upregulated on day 21. Conclusion Marine-derived type II collagen was, for the first time, fabricated into a fibril state. It showed rapid cellular affinity and induced chondrogenesis with extracellular secretions. We presented a new model for studying chondrogenesis in vitro and a potential alternative material for cell-laden CTE research.

Abstract
Purpose Limbal epithelial stem cells (LESCs) reside within a LSC niche (LSCN). We recently identified that hyaluronan (HA) is a major constituent of the LSCN, and that HA is necessary for maintaining LESCs in the "stem cell" state, both in vitro and in vivo. Herein, we characterized the LSCN to identify key components of the HA-specific LSCN. Methods The cornea and limbal rim were dissected from mouse corneas, subjected to mRNA extraction, and sequenced using a NextSeq 500 (Illumina) and data processed using CLC Genomics Workbench 20 (Qiagen) and the STRING database to identify key components of the LSCN. Their expression was confirmed by real-time PCR, Western blotting, and immunohistochemistry. Furthermore, the differential expression of key compounds in different corneal cell types were determined with single-cell RNA sequencing. Results We identified that the hyaladherins inter-alpha-inhibitor (IαI), TSG-6 and versican are highly expressed in the limbus. Specifically, HA/HC complexes are present in the LSCN, in the stroma underlying the limbal epithelium, and surrounding the limbal vasculature. For IαI, heavy chains 5 and 2 (HC5 and HC2) were found to be the most highly expressed HCs in the mouse and human limbus and were associate with HA-forming HA/HC-specific matrices. Conclusions The LSCN contains HA/HC complexes, which have been previously correlated with stem cell niches. The identification of HA/HC complexes in the LSCN could serve as a new therapeutic avenue for treating corneal pathology. Additionally, HA/HC complexes could be used as a substrate for culturing LESCs before LESC transplantation.

Abstract
Beer consumption has been identified as a risk factor for osteoarthritis (OA), a rheumatic disease characterised by cartilage degradation, joint inflammation, and eventual joint failure. One of the main isoflavonoids in beer is formononetin (FNT), an estrogenic compound also found in multiple plants and herbs. In this study, we aimed to investigate the effect of FNT on chondrocyte viability, inflammation, and metabolism. Cells were treated with FNT with or without IL-1β for 48 h and during 7 days of differentiation. Cell viability was determined via MTT assay. Nitrite accumulation was determined by Griess reaction. The expression of genes involved in inflammation and metabolism was determined by RT-PCR. The results revealed that a low concentration of FNT had no deleterious effect on cell viability and decreased the expression of inflammation-related genes. However, our results suggest that FNT overexposure negatively impacts on chondrocytes by promoting catabolic responses. Finally, these effects were not mediated by estrogen receptors (ERs) or aryl hydrocarbon receptor (AhR). In conclusion, factors that favour FNT accumulation, such as long exposure times or metabolic disorders, can promote chondrocyte catabolism. These data may partially explain why beer consumption increases the risk of OA.

Abstract
The journey into the field of stem cell biology has been an endeavor of paramount advancement in biomedicine, establishing new horizons in the avenue of materiobiology. The creative drive of the scientific community focuses on ameliorating the utilization of stem cells, which is currently untapped on a large scale. With similar motivation, we present a nascent strategy of maneuvering biogenic carbon quantum dots (CQDs) to eclipse the toxic hurdles of chemical synthesis of carbon allotropes to serve as a biocompatible trident in stem cell biology employing a three-prong action of stem cell differentiation, imaging, and migration. The derivation of CQDs from garlic peels as a biogenic precursor abets in realizing the optophysical features of CQDs to image mesenchymal stem cells without hampering the biological systems with cytotoxicity. We report the versatility of biogenic CQDs to generate reactive oxygen species (ROS) to robustly influence stem cell migration and concomitantly chondrocyte differentiation from human Wharton's jelly mesenchymal stem cells (hWJ-MSCs). This was orchestrated without the use of chondrogenic induction factors, which was confirmed from the expression of chondrogenic markers (Col II, Col X, ACAN). Even the collagen content of cells incubated with CQDs was quite comparable with that of chondrocyte-induced cells. Thus, we empirically propose garlic peel-derived CQDs as a tangible advancement in stem cell biology from a materiobiological frame of reference to hone significant development in this arena.

Abstract
Constitutive photomorphogenic 1 (COP1), is an E3 ubiquitin ligase that plays a role in the regulation of various cellular processes including cell growth, differentiation, and survival in mammals. In certain conditions such as overexpression or loss of function, COP1 acts either as an oncogenic protein or as a tumor suppressor by targeting specific proteins for ubiquitination-mediated degradation. However, the precise role of COP1 has not been well studied in primary articular chondrocytes. In this study, we investigated the role of COP1 in chondrocyte differentiation. Western blotting and reverse transcription-polymerase chain reaction analysis demonstrated that COP1 overexpression reduced type II collagen expression, promoted cyclooxygenase 2 (COX-2) expression, and reduced sulfated proteoglycan synthesis, as detected by Alcian blue staining. Upon siRNA treatment, revived type II collagen, sulfated proteoglycan production, and decreased COX-2 expression. Phosphorylation of p38 kinase and ERK-1/-2 signaling pathways was regulated by COP1 upon cDNA and siRNA transfection in chondrocytes. The inhibition of the p38 kinase and ERK-1/-2 signaling pathways with SB203580 and PD98059 ameliorated the expression of type II collagen and COX-2 in transfected chondrocytes, thus suggesting that COP1 regulates differentiation and inflammation in rabbit articular chondrocytes via the p38 kinase and ERK-1/-2 signaling pathway.

Abstract
BACKGROUND Osteoarthritis (OA) is a chronic degenerative disease that is one of the main causes of disability in middle-aged and elderly people. Adipose stem cell (ASC)-derived exosomes (ASC-Exo) could repair cartilage damage and treat OA. MiRNA-338-3p expression was confirmed to play a role in inhibiting proinflammatory cytokines. Herein, we aimed to explore the mechanism by which exosomes derived from miR-338-3p overexpressing ASCs protects chondrocytes from interleukin (IL)-1β-induced chondrocyte change. METHODS Exosomes were extracted from ASCs transfected with miR-338-3p or its antisense inhibitor. The ASC-Exos (miR-338-3p silencing/overexpression) were incubated with IL-1β-induced ATDC5 cells, followed by evaluation of the chondrocyte proliferation, degradation, and inflammation injury. RESULTS In vitro results revealed that ASC-Exos inhibited the expression of prostaglandin E2 (PGE2), IL-6, IL-1β, and TNF-α, as well as promoted the proliferation of ATDC5 cells. Moreover, ASC-Exos inhibited inflammation injury and degradation of ATDC5 cells by transferring miR-338-3p. Luciferase reporter assays showed that RUNX2 was a target gene of miR-338-3p. Additionally, RUNX2 overexpression in ATDC5 cells reversed the protective effect of miR-338-3p on chondrocytes. Taken together, this study demonstrated that exosomes secreted from miR-338-3p-modified ASCs were effective in the repair of IL-1β-induced chondrocyte change by inhibiting RUNX2 expression. CONCLUSIONS Our result provided valuable data for understanding the mechanism of ASC-Exos in OA treatment.

Abstract
Nanoconfinement within flexible interfaces is a key step towards exploiting confinement effects in several biological and technological systems wherein flexible 2D materials are frequently utilized but are arduous to prepare. Hitherto unreported, the synthesis of 2D Hydrogel nanosheets (HNS) using a template- and catalyst-free process is developed representing a fertile ground for fundamental structure-property investigations. In due course of time, nucleating folds propagating along the edges trigger co-operative deformations of HNS generating regions of nanoconfinement within trapped water islands. These severely constricting surfaces force water molecules to pack within the nanoscale regime of HNS almost parallel to the surface bringing about phase transition into puckered rhombic ice with AA and AB Bernal stacking pattern, which was mostly restricted to Molecular dynamics (MD) studies so far. Interestingly, under high lateral pressure and spatial inhomogeneity within nanoscale confinement, bilayer rhombic ice structures were formed with an in-plane lattice spacing of 0.31 nm. In this work, a systematic exploration of rhombic ice formation within HNS has been delineated using High-resolution transmission electron microscopy (HRTEM), and its ultrathin morphology was examined using Atomic Force Microscopy (AFM). Scanning Electron Microscopy (SEM) images revealed high porosity while mechanical testing presented young's modulus of 155 kPa with ~84% deformation, whereas contact angle suggested high hydrophilicity. The combinations of nanosheets, porosity, nanoconfinement, hydrophilicity, and mechanical strength, motivated us to explore their application as a scaffold for cartilage regeneration, by inducing chondrogenesis of human Wharton Jelly derived mesenchymal stem cells (hWJ MSCs). HNS promoted the formation of cell aggregates giving higher number of spheroid formation and a marked expression of chondrogenic markers (ColI, ColII, ColX, ACAN and S-100), thereby providing some cues for guiding chondrogenic differentiation.

Abstract
The complexity of skeletal pathologies makes use of in vivo models essential to elucidate the pathogenesis of the diseases; nevertheless, chondrocyte and osteoblast cell lines provide relevant information on the underlying disease mechanisms. Due to the limitations of primary chondrocytes, immortalized cells represent a unique tool to overcome this problem since they grow very easily for several passages. However, in the immortalization procedure the cells might lose the original phenotype; thus, these cell lines should be deeply characterized before their use. We immortalized primary chondrocytes from a Cant1 knock-out mouse, an animal model of Desbuquois dysplasia type 1, with a plasmid expressing the SV40 large and small T antigen. This cell line, based on morphological and biochemical parameters, showed preservation of the chondrocyte phenotype. In addition reduced proteoglycan synthesis and oversulfation of glycosaminoglycan chains were demonstrated, as already observed in primary chondrocytes from the Cant1 knock-out mouse. In conclusion, immortalized Cant1 knock-out chondrocytes maintained the disease phenotype observed in primary cells validating the in vitro model and providing an additional tool to further study the proteoglycan biosynthesis defect. The same approach might be extended to other cartilage disorders.

Abstract
C-type lectin receptors (CLRs) belong to the family of pattern recognition receptors (PRRs). They have a critical role to play in the regulation of a range of physiological functions including development, respiration, angiogenesis, inflammation, and immunity. CLRs can recognize distinct and conserved exogenous pathogen-associated as well as endogenous damage-associated molecular patterns. These interactions set off downstream signaling cascades, leading to the production of inflammatory mediators, activation of effector immune cells as well as regulation of the developmental and physiological homeostasis. CLR signaling must be tightly controlled to circumvent the excessive inflammatory burden and to maintain the cellular homeostasis. Recently, MicroRNAs (miRNAs) have been shown to be important regulators of expression of CLRs and their downstream signaling. The delicate balance between miRNAs and CLRs seems crucial in almost all aspects of multicellular life. Any dysregulations in the miRNA-CLR axes may lead to tumorigenesis or inflammatory diseases. Here, we present an overview of the current understanding of the central role of miRNAs in the regulation of CLR expression, profoundly impacting upon homeostasis and immunity, and thus, development of therapeutics against immune disorders.

Abstract
OBJECTIVE The presence or relative proportion of progesterone nuclear receptors (PR) in different tissues may contribute to sexual dimorphism in these tissues. PR is expressed in chondrocytes, but its function is mostly unknown. We hypothesized that the PR may regulate chondrocyte metabolism and affect subchondral bone structure. METHODS We utilized genetic fate mapping and immunohistochemistry to elucidate PR expression in and effect on cartilage. To define sex-dependent and chondrocyte-specific effects of the PR on subchondral bone, we selectively deleted PR in osteochondrogenic progenitor cells marked by Prx1 (Prx1; PRcKO) and Collagen 2 (Col2; PRcKO), or in matured chondrocytes marked by aggrecan (Acan; PRcKO) and evaluated subchondral bone structure at 4 months of age. Chondrocyte aging was monitored by anti-senescence marker p16INK4a, and MMP13, one of the Senescence-Associated Secretary Phenotype (SASP) components. RESULTS Compared to wild-type (WT) mice, the female Prx1; PRcKO and the Col2; PRcKO mice had greater total subchondral bone volume and greater subchondral cortical bone thickness, with increased estimated subchondral bone stiffness and failure load in both female and male Col2; PRcKO mice. Moreover, Col2; PRcKO mice from both sexes had greater bone formation and bone strength at the femurs. In contrast, we did not observe any subchondral bone changes in Acan; PRcKO mice other than higher work-to-failure observed in the male Acan; PRcKO mice. Despite no detected difference in articular cartilage between the WT and the PR; chondrocyte conditional deletion mice, there were greater numbers of senescent chondrocytes and increased MMP13 expression, especially in the male mutant mice. CONCLUSION These findings suggest that selective inhibition of PR in osteoprogenitor cells, but not in terminally differentiated chondrocytes, induced an increased subchondral bone phenotype and high estimated subchondral bone strength, which might be associated with the development of osteoarthritis in older age.

Abstract
Background To better understand the process of osteoarthritic degenerative meniscal lesions (DMLs) formation, this study analyzed the dataset GSE52042 using bioinformatics methods to identify the pivotal genes and pathways related to osteoarthritic DMLs. Material/Methods The GSE52042 dataset, comprising diseased meniscus samples and healthier meniscus samples, was downloaded and the differentially-expressed genes (DEGs) were extracted. The reactome pathways assessment and functional analysis were performed using the “ClusterProfiler” package and “ReactomePA” package of Bioconductor. The protein–protein interaction network was constructed, followed by the extraction of hub genes and modules. Results A set of 154 common DEGs, including 64 upregulated DEGs and 90 downregulated DEGs, were obtained. GO analysis suggested that the DEGs primarily participated in positive regulation of the mitotic cell cycle and extracellular matrix organization. Reactome pathway analysis showed that the DEGs were predominantly enriched in TP53, which regulates transcription of genes involved in G2 cell cycle arrest and extracellular matrix organization. The top 10 hub genes were TYMS, AURKA, CENPN, NUSAP1, CENPM, TPX2, CDK1, UBE2C, BIRC5, and CCNB1. The genes in the 2 modules were primarily associated with M Phase and keratan sulfate degradation. Conclusions A series of pivotal genes and reactome pathways were identified elucidate the molecular mechanisms involved in the formation of osteoarthritic DMLs and to discover potential therapeutic targets.
