Fluorescence labeling of MDA-MB-231 cells with acridine orange and ethidium bromide. The monolayer cultured cells after treatment with (a) DMSO 1% as control, (b) etoposide at a concentration equal to the IC50 as a positive control, and (c) stigma ethanol extract of C. cancellatus subsp. damascenus at a concentration equal to the IC50. Live cells are shown by the solid arrow; dashed and dotted arrows denote cells that are in the early and late stages of apoptosis, respectively. Fluorescence microscope images were captured at 400x magnification. (d) Percentage of cells that have undergone apoptosis. Data are shown as the mean and standard error of the mean based on three data points. compared to control.
