Flow cytometry of hDPSCs and odontoblastic differentiation of hDPSCs after induction for 14 days. a Representative diagrams are shown for the PE negative control, CD34, CD45, CD73, CD146, and CD166. b Representative diagrams are shown for the APC negative control and CD90. c, d The mRNA and protein expression levels of DMP-1 and DSPP increased during odontoblastic differentiation. e The number of mineralized nodules increased with the process of odontoblastic differentiation. f The ALP activity of hDPSCs was enhanced after differentiation induction. The data are presented as the mean ± SD in three independent experiments. *P < 0.05, **P < 0.01, ***P < 0.001
