Figure 10: Real-time RT-PCR analysis of the expression of osteogenesis-related genes in BMSCs cultured on the –NH2- and –CH3-modified substrates in the presence of 0, 10, 25, and 50 μM of PD98059 for 10 days. (a) Cbfα-1 and (b) ALP. versus the respective –CH3-modified substrate; versus the 0 μM dose group.
