HYSJD facilitates cell proliferation in HaCaT cells by up-regulating the expression of EGFR. (A and B) EFGR and IGF-1 expression levels measured by ELISA. A Serum EGFR levels (n = 6 per group). B Serum IGF-1 levels (n = 6 per group). C Cell viability at different concentrations of HYSJD (n = 6). D Immunofluorescence staining of Ki67 (green) and quantitative results (n = 3 per group), nucleus (blue), ×400 . Data were expressed as mean ± SD, and significance was expressed as ^#P < 0.05 and ^##P < 0.01 vs Ctrl and *P < 0.05 vs Model
