Ultrasound detection of native and regenerated aortas in WT and Apoe −/− rats, respectively, on Day 30 (a) and Day 90 (b). (c) M mode images of ultrasound of native and regenerated aortas in WT and Apoe −/− rats, respectively, on Day 30 and Day 90. Arrow heads indicate movement of vascular walls. Quantification of RI (d), PI (e) and compliance (f) of native and regenerated aortas in WT and Apoe −/− rats, respectively, on Day 30 and Day 90. ∗∗ indicates p < 0.01, N.S. indicates non-significant, Tukey's post-hoc test. For each time point and each group, five different images from five different animals were analyzed (n = 5). Tensile tests and elastic modulus of native and regenerated aortas in WT and Apoe −/− rats, respectively, on Day 30 (g) and Day 90 (h). ∗∗ indicates p < 0.01, Tukey's post-hoc test. For each time point and each group, five independent tests of five different samples from five different animals were conducted (n = 5).

Figure Legend Snippet: Downregulation of APOE by AAV ameliorating fibrosis during vascular regeneration after graft implantation in vivo . (a) Illustration of a strategy of adventitial delivery of AAV-shRNA(Apoe) to inhibit APOE levels in regenerated aortas after graft implantation in vivo . Two weeks after graft implantation in vivo , AAV-shRNA(Apoe) were injected into the adventitia of the regenerated aortas, which were then harvested for analysis three weeks later.

(c) Tensile tests of regenerated aortas treated with PBS, AAV-shRNA(NC), and AAV-shRNA(Apoe) for 3 weeks. (d) Quantification of RI, PI, and compliance of regenerated aortas treated with PBS, AAV-shRNA(NC), and AAV-shRNA(Apoe) for 3 weeks. ∗∗ indicates p < 0.01, Tukey's post-hoc test. For each group, six different images from six different animals were analyzed (n = 6).

(g) Immunofluorescence staining of COL I, COL III, elastin, αSMA, and eNOS in regenerated aortas treated with PBS, AAV-shRNA(NC), and AAV-shRNA(Apoe) for 3 weeks. L indicates lumens. Arrow heads indicate capillaries. Quantification of adventitia thickness (h), collagen positive areas according to MTC staining (i), elastin positive areas according to EVG staining (j), COL I positive areas (k), COL III positive areas (l), and number of capillaries (m) in adventitial areas of regenerated aortas.
