Figure 5From: Lipopolysaccharide preconditioning enhances the efficacy of mesenchymal stem cells transplantation in a rat model of acute myocardial infarctionLPS-preconditioned MSCs transplantation increased vascular density. A. Endothelial cells were stained with antibody against vWF, and blood vessel numbers were counted (× 100). B. Five fields were randomly selected from each sample (n = 8), and blood vessel density is shown as the vessel number/field. Data are mean ± SEM. *P < 0.01 vs. control group; #P < 0.01 vs. wMSCs group; §P < 0.01 vs. LPS-tMSCs group.Back to article page
