Cos induced apoptosis in 769-P cells. (A) Apoptotic nuclear morphology, as assessed using DAPI staining and visualized using fluorescence microscopy. (B) Percentage of Cos-induced apoptosis in 769-P cells, as measured using Annexin V-FITC/PI staining and flow cytometry. The histograms indicate the percentage of early apoptosis and late apoptosis. All results are presented as mean ± SD (n = 3). *p < 0.05; **p < 0.01, vs the control.
