Endothelial cell migration is preserved in hypercholesterolemic C57Bl/6 mice treated with D-4F, an apoplipoprotein A-I mimetic peptide. (A) Representative carotid arteries 120 hours after injury for mice in the chow, chow plus D-4F, high cholesterol (HC), and the HC plus D-4F groups are shown. The area stained by Evans Blue is the area that remained deendothelialized. The arrow identifies the length of the original injury. (B) Reendothelialization reported as a percentage of the original injury. Results are expressed as the mean ± standard error for mice in each group: chow (n=6), chow plus D-4F (n=6), HC (n=6), and HC plus D-4F (n=6).
