The inhibition of Dkk1 on the osteogenic and cementogenic differentiation of hPDLSCs cultured on mnHA bioceramics.
Notes: (A) The expression of osteogenic/cementogenic and Wnt signaling-related genes for hPDLSCs cultured on mnHA ceramics or with Wnt signaling pathway inhibitor Dkk1 treatment at day 7. The expression level of mRNA was normalized to GAPDH. *P<0.05. (B, C) ALP staining for hPDLSCs was performed on mnHA bioceramics (B) or with Wnt signaling pathway inhibitor Dkk1 treatment (C) at day 7. The circular insets show ALP staining of the whole disks; and the magnification of B and C is 10.
