Figure 3: Dark stained nuclei (arrows) of the MCF-7 and WEHI-164 cells were observed after cell treatment with the methanolic subfraction (Fa) of S. oxysepala, whereas no stained nuclei were noted in the untreated (control) cells and treated L929 cell. (a) MCF-7 control, (b) treated MCF-7, (c) WEHI-164 control, (d) treated WEHI-164, (e) L929 control, and (f) treated L929. Arrows indicate representative apoptotic cells. (a)–(f): 200x magnification.
