Cytotoxicity of MOE on Vero cells. (A) Light microscope of Vero cells treated with indicated concentrations of MOE at 37 °C for 24 h. (B) Vero cells were seeded in 96-well plates. After different concentrations of MOE ranging from 500 μg/mL to 5000 μg/mL were treated at 37 °C for 24 h and equal volume of PBS as Ctrl, cytotoxicity was determined by CCK8 assay. Data are expressed as three independent experiments. *** p < 0.001. MOE: the aqueous leaf extract of M. oleifera.
