Abstract
Fractures associated with Type2 diabetes (T2DM) are major public health concerns in an increasingly obese and aging population. Patients with obesity or T2DM have normal or better than normal bone mineral density but at an increased risk for fractures. Hence it is crucial to understand the pathophysiology and mechanism of how T2DM and obesity result in altered bone physiology leading to increased fracture risk. Although enhanced osteoclast mediated bone resorption has been reported for these patients, the most notable observation among patients with T2DM is the reduction in bone formation from mostly dysfunction in osteoblast differentiation and survival. Studies have shown that obesity and T2DM are associated with increased adipogenesis which is most likely at the expense of reduced osteogenesis and myogenesis considering that adipocytes, osteoblasts, and myoblasts originate from the same progenitor cells. Furthermore, emerging data point to an inter-relationship between bone and metabolic homeostasis suggesting that these physiologic processes could be under the control of common regulatory pathways. Thus, this review aims to explore the complex mechanisms involved in lineage differentiation and their effect on bone pathophysiology in patients with obesity and T2DM along with an examination of potential novel pharmacological targets or a re-evaluation of existing drugs to improve bone homeostasis.

Abstract
Conventional intake of drugs and active substances is most often based on oral intake of an appropriate dose to achieve the desired effect in the affected area or source of pain. In this case, controlling their distribution in the body is difficult, as the substance also reaches other tissues. This phenomenon results in the occurrence of side effects and the need to increase the concentration of the therapeutic substance to ensure it has the desired effect. The scientific field of tissue engineering proposes a solution to this problem, which creates the possibility of designing intelligent systems for delivering active substances precisely to the site of disease conversion. The following review discusses significant current research strategies as well as examples of polymeric and composite carriers for protein and non-protein biomolecules designed for bone tissue regeneration.

Abstract
Selective laser melting manufacture of patient specific Ti implants is serving as a promising approach for bone tissue engineering. The success of implantation is governed by effective osseointegration, which depends on the surface properties of implants. To improve the bioactivity and osteogenesis, the universal surface treatment for SLM-Ti implants is to remove the primitive roughness and then reengineer new roughness by various methods. In this study, the micro-sized partially melted Ti particles on the SLM-Ti surface were preserved for assembling mesoporous bioactive glass nanospheres to obtain a unique micro/nano- topography through combination of SLM manufacture and sol-gel processes. The results of simulated body fluid immersion test showed that bioactive ions (Ca, Si) can be continuously and stably released from the MBG nanospheres. The osseointegration properties of SLM-Ti samples, examined using pre-osteoblast cells, showed enhanced adhesion and osteogenic differentiation compared with commercial pure titanium commonly used as orthopedic implants. Overall, the developed approach of construction of the dual micro/nano topography generated on the SLM-Ti native surface could be critical to enhance musculoskeletal implant performance.

Abstract
Collagen and chitosan are two different kinds of natural biodegradable polymers commonly used in the regeneration of bone defects. Mesoporous bioactive glass (MBG) is a type of favorable bone filler which can effectively constitute an enlarged microenvironment to facilitate an exchange of important factors between the cells and scaffolds. Here we prepared a collagen-chitosan-MBG (C-C-MBG) scaffold which displayed significantly increased proliferation, differentiation and mineralization in bone mesenchymal stem cells (BMSCs). Additionally, we found that the scaffold can stimulate extra-cellular signal regulated kinase 1/2 (Erk1/2) activated Runx2 pathway, which is the predominant signaling pathway involved in osteoblast differentiation. Consistently, we observed that the scaffold can markedly enhance the expression ofType I collagen, Osteopontin(Opn), andRunx2, which are important osteoblastic marker genes implicated in the process of osteoblast differentiation. Therefore, we conclude that the composite scaffold can significantly promote the differentiation of BMSCs into osteoblasts by activating Erk1/2-Runx2 pathway. Our finding thereby implies that the C-C-MBG scaffold can possibly act as a potential biomaterial in the bone regeneration.

Abstract
The introduction of nanoparticles into bone tissue engineering strategies is beneficial to govern cell fate into osteogenesis and the regeneration of large bone defects. The present study explored the role of nanoparticles to advance osteogenesis with a focus on the cellular and molecular pathways involved. Pubmed, Pubmed Central, Embase, Scopus, and Science Direct databases were explored for those published articles relevant to the involvement of nanoparticles in osteogenic cellular pathways. As multifunctional compounds, nanoparticles contribute to scaffold-free and scaffold-based tissue engineering strategies to progress osteogenesis and bone regeneration. They regulate inflammatory responses and osteo/angio/osteoclastic signaling pathways to generate an osteogenic niche. Besides, nanoparticles interact with biomolecules, enhance their half-life and bioavailability. Nanoparticles are promising candidates to promote osteogenesis. However, the interaction of nanoparticles with the biological milieu is somewhat complicated, and more considerations are recommended on the employment of nanoparticles in clinical applications because of NP-induced toxicities.

Abstract
OBJECTIVE Mesoporous bioactive glass (MBG) has good biocompatibility without immune reaction after implanting into tissue as biomaterial which was used in the treatment of bone defect. Genistein (G), a phytoestrogen, could be used in the treatment of osteoporosis in postmenopausal women. RESULTS Here, we report that MBG with large pores (MBG-L) and MBG-L adsorbed with G (MBG-L/G) sustained-release G could enhance osteoblast differentiation and matrix mineralization. Interestingly, we observed that MBG-L enhanced the formation of bone-like deposit and Ca deposition in vitro. In the other side, we also found that MBG-L/G substrate could promote osteoblast differentiation and matrix mineralization through Erk activated Runx2 pathway. Interestingly, the expression of osteoblast-specific marker gene Osteopontin (Opn) was also increased in MC3T3-E1 cells cultured on MBG-L/G substrate. CONCLUSIONS We conclude that MBG-L/G is a potential biomaterial for the treatment of bone defect.

Abstract
Mesoporous bioactive glass (MBG) is performed as a bone tissue engineering material because of its good bioactivity, biocompatibility and osteoinducion characteristics. Here, we propose MBG with larger pores (MBG-L) adsorbed fibroblast growth factor (FGF) to facilitate osteoblast differentiation and matrix mineralization. Specifically, we observed that MBG-L promotes calcium deposit precipitation in vitro. In addition, adhesion, proliferation, differentiation and matrix mineralization were promoted after osteoblast cultured on MBG-L/FGF. Interestingly, we found that the transcriptional activity of the critical transcription factor Runx2 was increased through MAPK pathway after osteoblast cultured on MBG-L/FGF. Support for this result, we found that the expression of osteoblastic marker genes, Osteocalcin (Ocn), Osteopontin (Opn), and Runx2 were increased. Thus, our findings provided that MBG-L/FGF could be a promising new material in bone tissue engineering.

Abstract
Stanozolol (ST) is a synthetic androgen with high anabolic potential. Although it is known that androgens play a positive role in bone metabolism, ST action on bone cells has not been sufficiently tested to support its clinical use for bone augmentation procedures. Objective: This study aimed to assess the effects of ST on osteogenic activity and gene expression in SaOS-2 cells. Material and Methods: SaOS-2 deposition of mineralizing matrix in response to increasing doses of ST (0-1000 nM) was evaluated through Alizarin Red S and Calcein Green staining techniques at 6, 12 and 24 days. Gene expression of runt-related transcription factor 2 (RUNX2), vitamin D receptor (VDR), osteopontin (SPP1) and osteonectin (ON) was analyzed by RT-PCR. Results: ST significantly influenced SaOS-2 osteogenic activity: stainings showed the presence of rounded calcified nodules, which increased both in number and in size over time and depending on ST dose. RT-PCR highlighted ST modulation of genes related to osteogenic differentiation. Conclusions: This study provided encouraging results, showing ST promoted the osteogenic commitment of SaOS-2 cells. Further studies are required to validate these data in primary osteoblasts and to investigate ST molecular pathway of action.
