Decreased proliferation ability and differentiation potential of mesenchymal stem cells of osteoporosis rat

Objective:To explore decreased proliferation ability and differentiation potential of mesenchymal stem cells(MSCs) of osteoporosis rat.Methods:MSCs were obtained from osteoporosis rat,and proliferation potency and impaired osteogenic differentiation potential were determined.Results:The result showed a significant downregulation of MSCs pluripotency related gene(Oct4) and osteogenic genes(BSP,OCN) expression in OVX MSCs compared with Sham MSCs(P<0.05).Conclusions:These data suggest that MSCs are aging in osteoporosis body,and autologous OVX MSCs transplantation is not appropriate to treat osteoporosis if necessary.There will be a possibility in establishing a new clinical application of MSCs autologous transplantation to treat osteoporosis,if OVX MSCs have stronger proliferation and differentiation.
