The effects of TFP on the cell cycle distribution of U251, SWOZ2 and SWOZ2-BCNU cells. (A) Flow cytometry analysis of the cell cycle distribution of SWOZ2, SWOZ2-BCNU and U251 cells after incubation with TFP or control. (B–D) The cell cycle distribution of SWOZ2, SWOZ2-BCNU and U251 cells after treatment with TFP or control. The results are presented as the mean ± SD of three experiments. *P < 0.05 compared with the control.
