EA inhibited HSFs proliferation in a dose-dependent manner. A The structural formula of EA. B Cytotoxicity assay result for HDFs, as detected using CCK-8 assay (n = 3). HSFs proliferation in different experimental groups, as detected using CCK-8 assay at the indicated timepoints (n = 5). C Over trends in growth and D inter-group comparisons are shown. Data are presented as mean ± SD; #P > 0.05, *P < 0.05 and **P < 0.01
