Characterization of DPSCs. DPSCs at different culture passages (P2-P30) were characterized by (A, B) flow cytometry for CD90, CD105, CD73, CD45, EpCAM, CD31 surface markers; (C) real-time PCR for CD44, CD90, CD105, CD45, ALPL, DSPP, p16, p21 gene expression; (D) BrdU assay, for their proliferation rate
