(A) Flow cytometry detection of apoptosis following annexin V-FITC/propidium iodide (PI) labelling. The lower left quadrant (Q3) contains viable cells, the lower right quadrant (Q4) contains early apoptotic cells, the upper right quadrant contains late apoptotic cells, and the upper left quadrant contains non-viable necrotic cells (Q1). A bar graph displaying the mean values from three independent experiments for (B) 1321N1, (C) SW1783, and (D) LN18. *p < 0.05 compare to control early or late apoptosis respectively, #p < 0.05 compare to EGCG early or late apoptosis respectively, $p < 0.05 compare to HC early or late apoptosis respectively.
