PER2 inhibited stemness in GSCs. (A) Tumor area measured by in vivo imaging system (IVIS) showed PER2 suppressed tumorigenic capacity of GSCs in vivo. (B) IHC of nude tumors showed a reduced number of Ki-67 positive cells in PER2 overexpression group compared with the control. One-way ANOVA with Tukey's post was used for statistical analysis of the results of A. *P<0.05, **P<0.01 vs. the control. PER2, period 2; GSCs, glioma stem cells; IHC, immunohistochemistry.
