Overexpression of miR-21 in ADSCs leads to the upregulation of HIF-1α, VEGF, SDF-1, p-Akt, p-ERK1/2 and downregulation of PTEN. (A) Quantification of the expression level of miR-21, HIF-1α, VEGF, SDF-1 in ADSCs with and without miR-21 overexpression. (B,C) Western blot and its quantification of the expression level of HIF-1α, VEGF, SDF-1, PTEN, p-Akt, Akt, p-ERK1/2, ERK1/2 in ADSCs with (2) and without miR-21 overexpression (1). (D,E) Western blot and its quantification of the expression level of HIF-1α, VEGF, SDF-1 in exosomes isolated from ADSCs with (2) and without (1) miR-21 overexpression. Error bars were calculated based on triplicates. (^***means p < 0.001 vs. ADSCs- miR-21 control, ^**means p < 0.01 vs. ADSCs- miR-21 control, ^*means p < 0.05 vs. ADSCs- miR-21 control).
