Figure 3. ALP activity and marker expression were increased during osteogenesis. A, The activity of ALP was determined in hFOB1.19 cells cultured with growth medium (GM) or osteogenic medium (OM) (14d). B, The expression of osteogenic differentiation markers was determined by western blot assay. Data are reported as means±SD of three independent experiments. *P<0.05 (t-test).
