Figure 6From: Myocardial transfection of hypoxia-inducible factor-1α and co-transplantation of mesenchymal stem cells enhance cardiac repair in rats with experimental myocardial infarctionCapillary densities in the infarction region in each group. A) More capillary densities were detected in the hypoxia-inducible factor-1α (HIF-1α) + mesenchymal stem cells (MSCs) group than other groups. (I) HIF-1α + MSCs group, (II) HIF-1α group, (III) HIF-1α-MSCs group, (IV) MSCs group, (V) Control group. B) The number of the CD-31-stained capillary was expressed as the number/mm2. &P <0.01 vs. HIF-1α group, ☆P <0.01 vs. HIF-1α-MSCs group, △P <0.01 vs. MSCs group, * P <0.01 vs. Control group, #P <0.05 vs. Control group.Back to article page
