Fig. 3From: Poly(ADP-ribose) polymerase inhibitors activate the p53 signaling pathway in neural stem/progenitor cellsSuppression of cell cycle progression of NSPCs by PJ34. Progression of the cell cycle with or without PJ34 was analyzed by thymidine incorporation, followed by flow cytometry. The ratios of cells in the G1, S, and G2/M phases are illustrated every 2 h after the onset of the S phase. The results of flow cytometry at the peak of the G2/M or G1 phase are shown. Data represent the mean value ± SEM (n = 3)Back to article page
