Assessment of wound closure. Wounds were imaged on days 3, 6, 9, 12 and 14. Actual wound sizes were calculated using ImageJ software. a Wound areas were marked by a white line in all representative images. b Percentages of wound contraction are expressed as the mean ± standard deviation from three independent animal experiments. Statistical analysis was performed using Student’s two-tailed t-test, *P < 0.05
