Figure 4. Flow cytometric evaluation of HUVEC apoptosis. Histograms derived from flow cytometry comparing apoptotic cells between vehicle and indicated concentrations of TS treated cells. After treatment for 24 h, the induction of apoptosis was determined using flow cytometric analysis of Annexin V-FITC and PI-stained HUVECs. Cells in the lower right quadrant indicate Annexin-positive, early apoptotic cells, and cells in the upper right quadrant indicate Annexin-positive/PI positive, late apoptotic cells. Data were the mean result from three parallel experiments
