Abstract: Objevtive: To investigate the effect of platelet-rich plasma (PRP) at different concentrations on the mineralization of human bone marrow stromal cells. Methods: BMSCs from healthy donor were cultured and passaged for 3-4 passages. PRP were manufactured from venous blood of the same donor. The activity of alkaline phosphatase in BMSCs was detemined using alkaline phosphatase reagent kit on the 7th day after mineralization induction. The formation of mineralized nodules in BMSCs were observed by alizarin red staining on the 21th days after minralization induction. After 7 days of minralization induction the expression of gene Runx2 in BMSCs was measured by real-time PCR. Results: PRP at the concentration of 5% evidently promoted the alkain phosphatase activity and the formation of mineralized nodules in BMSCs. The expression of gene Runx-2 was also evidently enhanced. Conclusion: PRP at the concentration of 5% could promote the mineralization of BMSCs.
