Osthole reverses defective osteogenic ability of P-PDLSCs. (A) ALP staining and ARS staining after 7 days (ALP staining) and 21 days (ARS staining) in H-PDLSCs and P-PDLSCs with different concentrations of Osthole (0 Mol/L, 10−4 Mol/L, 10−5 Mol/L, 10−6 Mol/L, 10−7 Mol/L and 10−8 Mol/L). (B) Quantification of ARS staining for light absorbance at 562 nm. (C) Gene expression of Runx2, ALP and Osterix in H-PDLSCs, P-PDLSCs and P-PDLSCs with 10−7 Mol/L Osthole as assayed by qRT-PCR. (D) Protein expression of Runx2, ALP and Osterix in H-PDLSCs, P-PDLSCs and P-PDLSCs with 10−7 Mol/L Osthole as assayed by Western blot. *P < 0.05, **P < 0.01, ns: P ≧ 0.05, n = 3.
