Effect of Dicentrine on cell viability. (A) BJ-EHLT (blue line) and BJ-hTERT (orange line) fibroblasts or (B) HeLa cells were treated for 72 h with increasing doses of Dicentrine (1, 5, 10, 25 and 50 µM) or with DMSO (negative control). Cell viability was determined with a colorimetric crystal violet assay. Results are expressed as the percentage of viable cells over the negative control. Histograms show the mean values ± SD of three independent experiments. * p < 0.05; ** p < 0.01; *** p < 0.001.
