Figure 4From: Isodeoxyelephantopin from Elephantopus scaber (Didancao) induces cell cycle arrest and caspase-3-mediated apoptosis in breast carcinoma T47D cells and lung carcinoma A549 cellsAcridine orange/ethidium bromide double staining to analyze the apoptotic morphology of IDOE treated tumor cells. (A) Untreated A549 control cells, (B) A549 cells treated with 10.46 μg/mL IDOE, (C) Untreated T47D control cells, and (D) T47D cells treated with 1.3 μg/mL IDOE. Viable cells (bright green nuclei); early apoptotic cells (bright green condensed nuclei); late apoptotic cells (red nuclei with condensed or fragmented chromatin) under fluorescent microscopy.Back to article page
