Effect of CMF on cytotoxicity in normal human liver cells and on cell viability in K562 cells. (a) Cytotoxic effects of CMF on normal human liver L-02 cells assessed by MTT assay. (b) Cell viability of K562 cells treated with various concentrations of CMF for 24, 48 and 72 h, evaluated by MTT assay. (c) Morphological study of K562 cells treated with CMF (300 μg/ml) for 48 h with inverted light microscope (×100). Data are means ± S.D. of three repeats. *P< 0.05 and **P< 0.01 vs. untreated control
