Time course analyses of endothelial cell apoptosis and tumor cell apoptosis. Endothelial cell apoptosis was determined by platelet/endothelial cell adhesion molecule (CD31)–TUNEL double staining assay. Tumor cell apoptosis was evaluated by TUNEL staining assay. The number of apoptotic endothelial cells and tumor cells was counted in nine random fields at ×400 magnification. Data were obtained from tumor tissues from mice in each treatment group and are plotted as mean ± SD. a P < 0.05 versus control; b P < 0.05 versus endostar; c P < 0.05 versus radiation.
