(A) Strophanthidin effectively suppresses the growth of human cancer cell lines. Cell viability of Strophanthidin in cancer cells (i) in comparison with normal cell lines (ii). Plots show mean values ± SE of quadruplicates with determinations of three or more experiments at P < 0.05. (B) MCF-7, A549, and HepG2 cells were treated with strophanthidin for 24 or 48 h. Morphological changes in the cells were observed. Representative images were obtained at 40X magnification. Scale bar: 50 μm.
