BMP2 has been reported to regulate stem cell proliferation and differentiation [21, 22]. Our information also recommend that the proliferation with the transplanted hUCMSCs might advantage from BMP2 within a constructive feedback mechanism. Differentiation of hUCMSCs into osteocytes requires the involvement of intrinsic signaling pathways. Among the intracellular signaling pathways, the phosphoinositide 3kinase and AKT (protein kinase B) signaling pathway (PI3KAKT) plays a central function inside the manage of cell survival, growth, and proliferation throughout the body. Moreover, GW-870086 Biological Activity PI3KAKT is also reported as a central nexus within the extensive network of extracellular signaling pathways that manage osteoblasts [23]. On the other hand, the biological effects of AKT around the osteodifferentiation of hUCMSCs remain an underexplored area of investigation. Inside the present study, we observed a larger volume of moved bone within the AKT inhibitor group with decreased biomechanical strength. These outcomes show an imbalance in the bone remodeling process, and bone fragility leading to bone fractures upon applying biomechanical stress. Our data may well contribute insight for the mechanism of osteoporosis, which can be characterized by low bone density and deterioration of bone microarchitecture [24]. Tsuji et al. reported that the earliest measures of fracture healing look to become blocked in bones lacking BMP2 [25]. In our study, we did not observe obvious differences in the expression of BMP2 in each stem cell transplantation groups. This, collectively with all the locating of reduced OPG expression in the AKT inhibitor group, confirms a cellautonomous regulation of OPG by AKT.
