Treated HepG2 stained with AO/PI observed under fluorescence microscope. Photographic documentation was carried out at 40x magnification. a Control (untreated) cells (b) Cell treated with FAA at 24Â h (c) 48Â h (d) 72Â h. Treated cells showed the typical characteristic of apoptosis such as nuclear margination (NM), chromatin condensation (CC), nuclear fragmentation (NF), membrane blebbing (MB), and membrane loss (ML)
