Wnt/β-catenin pathway was involved in angiogenesis induced by OPC
transplantation after tMCAO. (a) Western blot of Wnt7a expression in
sham, PBS and OPC groups at 14 days after tMCAO. (b) Western blot of
β-catenin expression. (c) Western blot of VEGF expression. (d)
Immunofluorescent images of β-catenin (green)/GFAP (red), β-catenin
(green)/NeuN (red) and β-catenin (green)/CD31 (red). White arrows
indicated β-catenin expression. Scale bar = 50 µm. Data are mean ± SD,
n = 4 per group, *p < 0.05,
**p < 0.01, NS>0.05.
