5-Ethynyl-2’-deoxyuridine (EdU) staining to detect cell proliferation. A U87 cells were treated with EdU for 6 h prior to click reaction. B U251 cells were treated with EdU for 6 h prior to click reaction. Data analysis was performed to calculate the signal intensity in EdU-positive cells based on individual DAPI signal and displayed in the right graph. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001.Error bars indicate mean ± SD
