The effect of CK on the neurosphere-forming ability of glioblastoma stem-like cells. GSCs derived from (A) U87MG and (B) U373MG were treated with different concentration of CK (10, 25 and 50 µM) for 9–12 days. The number of formed neurospheres in each well was counted under a microscope. Scale bar, 100 µm. ^*P<0.05 vs. the control.
