Identification of the pro-angiogenesis molecules in SCs-Exos and the inhibitory efficiency of integrin-β1 siRNA. (A) Western blotting was used to detect the protein level of VEGF-A, integrin-β1 and integrin-α1 in SCs and SCs-Exos. (B) The relative protein expression levels of VEGF-A, integrin-β1 and integrin-α1 in SCs-Exos (C,D). Western blotting and qRT-PCR were performed to analyze the inhibitory efficiency of integrin-β1 siRNA. The data are presented as mean ± SD. **p < 0.01 sh Integrin-β1 group vs. ctrl shRNA group. N = 3 in each group.
