Effects of hesperetin on cell cycle and apoptosis in VEGF-induced HUVECs. (A) HUVECs were treated with hesperetin (0~100 μM) for 24 h, stained with propidium iodide (PI) and then analyzed on a FACSCalibur flow cytometer. Quantitation of the PI staining data is presented as the percentages of cell cycle distribution. (B) HUVECs were treated with hesperetin (0~100 μM) for 24 h, stained with Annexin V and PI and analyzed on a FACS Vantage SE flow cytometer. The expressed as the mean±SD. ^*P<0.05 compared to control.
