The effect of FT-EtOH extract on the cell viability and THb induction in K562 cells. (i) K562 cells were treated with indicated concentrations of FT-EtOH extract for 2 days. The cell viability (filled square) was then estimated by MTT assay. (ii) K562 cells were treated with indicated concentrations of FT extract for 6 days. The Hb-positive cells were stained by TMB assay and the percentage of stained cells (filled triangle) was calculated. The results are expressed as mean  ±  SD of three cultures. The data are representative of three separate experiments. ^# P < .05, significant difference in cell viability when compared with non-treated group. *P < .05, significant difference in the number of TMB-stained cells when compared with non-treated group.
