Shh and AKT signaling pathway inhibitors abolish the effect of EGCG on the growth of DPCs and ORSCs. (A,B) After treatment with EGCG and/or cyclopamine, GANT61 or LY294002, the cell viability of DPCs and ORSCs was assessed by MTT assay. (C,D) Protein levels of cyclinB1 and cyclinD1 in DPCs and ORSCs were assessed by western blot with β-actin as the internal reference. All experiments were repeated three times. The results are presented as mean ± SD. ###p < 0.001 compared with the control group; ∗∗∗p < 0.001 compared with the EGCG group.
