The quantitative analysis of mRNA expression of HIF-1α, SDF-1α and VEGF. A1, A2, A3: mRNA expression levels of hypoxia-inducible factor-1α (HIF-1α) in peri-infarcted region at one week, two weeks and four weeks after operation in each group, respectively. B1, B2, B3: mRNA expression levels of stromal cell-derived factor-1α (SDF-1α) in the peri-infarcted region at one week, two weeks and four weeks after operation in each group, respectively. C1, C2, C3: mRNA expression levels of vascular endothelial growth factor (VEGF) in the peri-infarcted region at one week, two weeks and four weeks after operation in each group, respectively. The expression levels were normalized to the Control group. ☆P <0.01 vs. HIF-1α- mesenchymal stem cells (MSCs) group, △P <0.01 vs. MSCs group, * P <0.01 vs. Control group, ※P <0.01 vs. SHAM group, ▲P <0.05 vs. MSCs group, # P <0.05 vs. Control group, § P <0.05 vs. SHAM group.
