ASCs-exos activated the Wnt3a/β-catenin signaling pathway in vivo. (A,B) Comparison of signaling pathway-related protein levels in BMSCs treated with PBS, AEFS or ASCs-exos by Western blot analyses. (C,D) The protein expression of Wnt3a, Wnt5a, Wnt8a and Wnt10b was assessed by Western blot analyses. Data are presented as the mean ± SD, and all experiments were repeated three times. ** p < 0.01, **** p < 0.001, # p > 0.05.
