MPSS-loaded stent-grafts reduced inflammation and alleviated extracellular matrix degradation in AD model. A H&E staining was performed in each group, bar =100 μm; B Inflammation scores were compared among groups; C EVG staining was performed in each group, bar =100 μm; D Elastic fiber area of media area (%) was compared among groups; E Masson staining was performed in each group, bar =100 μm; F Collagen area of media area (%) was compared among groups. The data are expressed as mean ± SD. Statistical significance:. * P < 0.05; ** P < 0.01; *** P < 0.001. Ns indicates no significance
