Effect of luteolin (L) on osteogenic differentiation in HPDLCs. The effect of luteolin at different concentrations (0, 0.01, 0.1, 1, 10, 100 μmol/L) on osteogenic differentiation in HPDLCs were studied by ALP activity (a), calcified nodules formation and calcium deposition (b, c) according to the ALP and Alizarin Red S staining assay.**P < 0.001, vs. Control. ##P < 0.001, #P < 0.05, vs. L100
