Analysis of hPDLSCs cementogenic-osteogenic differentiation after 7-day treatment in the osteogenic medium under different experimental conditions. (A) Representative figures for each condition showing ARS calcified deposits. (B) quantification (in nM) of extracted ARS calcified deposits. (C) the concentration of alkaline phosphatase (ALP; in ng/mL) measured at supernatants. (D–G) relative gene expression. (mRNA) of cementogenic-osteogenic markers (Runx2, Osteocalcin/OCN, CEMP1, and CAP) evaluated by qPCR using GAPDH as endogenous control and the ΔΔCT method. (*) p < 0.05 vs control (non-stimulated); (§) p < 0.05 vs IL-1β treated group; (Δ) p < 0.05 vs TNF-α treated group; and (ø) p < 0.05 vs IL-1β +TNF-α treated group.
