(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. (E) qRT-PCR showed gene expression of fifteen histone acetylases in P-PDLSCs and P-PDLSCs with 10-7 Mol/L Osthole measured by qRT-PCR. (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. [Extracted from the article]
