ABSTRACT
Objective@# To investigate the effects of different glucose concentration on the proliferation and osteogenic differentiation of human bone marrow mesenchymal stem cells (hBMSC) in vivo@*Methods@#Cultured with basal medium containing different glucose concentrations, CCK-8 cell proliferation was detected at 1, 4, 7, 10 days. The osteogenic differentiation of human bone marrow mesenchymal stem cells was observed at 7 d, which was induced by osteogenic differentiation medium with different concentration of glucose. The expressions of alkaline phosphatase (ALP), osteocalcin (OC) and collagen type I (Col-1) gene were detected by real-time fluorescence quantitative PCR. Mineralized nodule formation was displayed by calciumalizarin red staining on the seventh day.@*Results @#10 mM glucose stimulated proliferation of hBMSC, while the higher (>30 mM) inhibited the proliferation (P < 0.05); Osteogenic induction can induce osteogenic differentiation of hBMSC, but the increase of glucose concentration will decrease the formation of mineralized nodules of hBMSC, inhibit the expression of osteogenic marker genes ALP, OC and Col-1 (P < 0.05).@*Conclusion@#The expression of Col-1, ALP and OC in osteoblast was down-regulated by high glucose, and the hBMSC proliferation was inhibited. At the same time, high glucose can reduce the osteogenic mineralization ability of stem cells and indirectly affect bone formation and metabolism.
