Epigallocatechin-3-gallate (EGCG) accelerates the growth of DPCs and ORSCs. (A,B) After treatment with 0.25, 0.5, 1, 2, and 4 μM EGCG for 12, 24, and 48 h, the cell viability of DPCs and ORSCs was assessed by MTT assay. $p < 0.05 for 12 h, ∗∗∗p < 0.001 for 24 h, ###p < 0.001 for 48 h, all compared with the control group. (C) After treatment with different concentrations of EGCG, the protein level of cyclinB1 in DPCs and ORSCs was detected by western blot. β-actin served as the internal reference. (D) Western blot was performed to detect the protein level of cyclinD1 in DPCs and ORSCs after treatment with EGCG. All experiments were repeated three times. The results are presented as mean ± SD.
