Figure 2: Effects of FLCWK on 5-FU-induced apoptosis. Apoptosis was measured using annexin V/PI staining followed by flow cytometric analysis. A: Typical scatter plots of annexin V (x-axis) vs. PI (y-axis) in every experimental group. B: Percent of apoptotic cells. Data are shown as the mean±SD of three independent experiments. *P<0.05 compared to the control, **P<0.01 compared to the control; #P<0.05 compared to the 5-FU group, ##P<0.01 compared to the 5-FU group. FLCWK: Feng-liao-chang-wei-kang; 5-FU: 5-fluorouracil.
