: Effects of emodin and aloe-emodin on cell migration of CCD-1079Sk skin fibroblasts after 24 h treatment. The images of the wound areas were taken before and after treatment. The cells were treated with 6.25 µM, 12.5 µM, and 25 µM emodin; 2.5 µM, 5 µM, 10 µM aloe-emodin concentrations. Data are expressed as mean ± SD, *p < 0.05 and **p < 0.01 versus the control group
