The cytotoxicity of apigenin to epithelial cells. (a) The chemical structure of apigenin. (b) NA, (c) HA and (d) P3HR1 cell lines were treated with apigenin for 24 h. Cell viability was determined by WST-1 assay, as described in Methods. The values are means ± SD from at least two separate experiments. CC50 values also were calculated and are given at the top of each group
