In vitro differentiation and mineralization of BMSCs induced by different substrates. A Representative photographs of ALP and ARS staining of BMSCs cultured on different groups at the indicated time points. B ALP relative activity of BMSCs on different surfaces at 3 and 7 days after culturing (n = 4). C Quantification of mineralized nodules at 14 and 21 days after culturing (n = 4). Relative expression of osteogenesis-related genes D) OCN, E) OPN, and F) BSP at 7 days after culturing (n = 3)
