The results of Western blot.

<p>(a, c) were the in vitro result and (b, d) were the in vivo result. (a) The protein expression of elastin in control group, ADSCs and BMSCs co-cultured group at 0, 7, 14 and 21 d. β-actin was loading control. (b) The protein expression of elastin in sham-operated group, control group and ADSCs group at 28 d. (c, d) The bar graphs showed mean ± SD of the ratio elastin/β-actin band intensity. P<0.05.
