Figure 1: Effects of Hibiscus syriacus L. flower (HSF) absolute on proliferation in HaCaT cells. HaCaT cells were seeded (2 × 103 cells) and then incubated with recombinant human epidermal growth factor (EGF; 50 ng/mL) or HSF absolute (0.001–0.1 mg/mL) for 48 h. Cell proliferation was tested using the XTT assay. The quiescent state of the cells was expressed as 100% (n = 4). EGF was used as a positive control. Data are expressed as the mean ± SE. *P value less than 0.05 versus quiescent state. |
