From: The crude ethanol extract of Periplaneta americana L. stimulates wound healing in vitro & in vivo
HSF cell migration assay. The migration of HSF cell was measured with wound scratch assay. a Significant migration was observed in cells treated with the PAL crude ethanol extract (0.05, 0.5 and 2 mg/mL) compared with the blank control group. b The quantitative evaluation and statistical analysis of wound closure percentage in wound scratch assay measured by Image J software. Results are expressed as mean ± SD of three experiments (*P < 0.05, versus blank control)
