Keratinocyte migration using a scratch assay after 24 h of incubation with lupeol. Cells were incubated with lupeol in different concentrations at 0.1, 1, 10, or 20 µg/mL or DMSO 0.25% at 10 µg/mL as negative control. (A) Representative images of scratch assay at 0 and 24 h. Lu: lupeol. (B) Effect of lupeol on migration cell. Data are expressed as mean ± standard error of the mean (SEM). ** p < 0.01 and *** p < 0.001 versus control group.
