RNA samples from the skin of normal and diabetic mice injured after 1, 3, 5, 7, 11, 15 days were analyzed for expression of Activin and Follistatin (relative to Gapdh) by RT-PCR. The scale of Activin and Follistatin was shown. Bars indicate mean value ± SD. n = 8 mice in each time point. Two-sample equal variance t-test followed by Bonferroni’s correction was used. ^★P < 0.05 and ^★★P < 0.001 compared with normal mice
