Resveratrol induces endothelial cell apoptosis. Confluent BAECs were starved for more than 4 h and then the cells were incubated for additional hours (0, 4, 8, 12, 24 or 72 h) with the indicated doses of resveratrol (RES). Consecutively, the cells were incubated for additional hours (0, 4, 8, 12, 24 or 72 h) We then counted the apoptotic cells (round shrunken cells) under the microscope. The line graphs represent the percentages of apoptotic cells (means±S.E.). The experiments were independently performed at least three times.
