Effects of acitretin on cell growth of SCL-1 cells. (A) SCL-1 cells and HaCaT cells were treated with acitretin at five different concentrations for 3 days. (B) SCL-1 cells and HaCaT cells were treated with 10−5 M of acitretin for various times. Cell proliferation was assessed by MTT assay. Cell viability was estimated from the equation: % of cell viability = 100 × At/Ac, where At and Ac are the absorbencies in treated and control cultures, respectively. Data are shown as median of three different independent experiments (each with three cultures).
