摘要:
In this study, adult human bone marrow-derived stromal cells (hBMSCs) were cultured in extracts of magnesium (Mg) and the Mg alloys AZ91D and NZ30K for 12 days. We studied the indirect effects of Mg alloys on hBMSC viability. Alkaline phosphatase activity and the expression of osteogenic differentiation marker genes were used to evaluate the effects of the Mg alloys on the osteogenic differentiation of hBMSCs. The results indicate that <= 10 mM concentration of Mg in the extracts did not inhibit the viability and osteogenic differentiation of hBMSCs. However, the results suggest that the high pH of the extracts, which is a result of the rapid corrosion of Mg and the Mg alloys, is unfavorable to the viability and osteogenic differentiation of hBMSCs.
