Induction of apoptosis of SGC-7901 cells following the treatment with FAFs. After incubation with various concentrations of FAFs for 48 h, the cells were examined using TEM. 1, Control cells; 2, cells incubated with FAFs (4 μg/ml); 3, FAFs (8 μg/ml); 4, FAFs (16 μg/ml) and 5, FAFs (32 μg/ml). The cells treated with FAFs (16–32 μg/ml) showed typical apoptotic phenomena and apoptotic bodies has been found (arrows). Scale bar,1 μm. FAFs, Flos Albiziae flavonoids; TEM, transmission electron microscopy.
