The expressions of HIF-1α and VEGF in the left ventricle after accepted hAFMSCExos or PBS treatment. (A) The levels of HIF-1α and VEGF expression in the left ventricle after accepted hAFMSCExos or PBS treatment by Western blot analysis. (B) Quantitative analysis showed that the expressions of HIF-1α and VEGF in the left ventricle after accepted hAFMSCExos or PBS treatment by Western blot analysis. #, P<0.005 vs. PBS group; ##, P<0.001 vs. PBS group. HIF-1α, hypoxia-inducible factor 1 α; VEGF, vascular endothelial growth factor; hAFMSCExos, human amniotic fluid mesenchymal stem cell-derived exosomes; PBS, phosphate-buffered saline.
