Figure 4From: Cytotoxic effect of Alpinia scabra (Blume) Náves extracts on human breast and ovarian cancer cells Morphological observation of MCF7 cells treated with the cytotoxic leaf hexane and chloroform extracts under phase-contrast inverted microscope (magnification 200×). Arrows indicate (A) cell shrinkage and (B) membrane blebbing as evidence of apoptosis. Note that the cells were treated with the following concentrations of extracts: a = 19.3 μg/ml, b = 15.30 μg/ml, c = 16.33 μg/ml and d = 18.80 μg/ml. Figures shown were obtained from at least three independent experiments with similar parameter.Back to article page
