SMC-MR deletion does not alter aortic root plaque size or composition in young ApoE−/− mice after 8 weeks of high fat diet. Representative histological images are shown for aortic root sections stained with: (A) Oil Red O (ORO); (B) PicroSirius Red for collagen; (C) Mac2/Galectin-3 immunofluorescence; and (D) Smooth muscle α-actin (SM-Actin) immunofluorescence, with the Mac2 and SM-Actin merged images shown in (E). Plaque area is quantified in (F) along with plaque composition, including lipid content and necrotic core area. (G) Collagen content, (H) Mac2 positive area, and (I) SM-Actin positive area are quantified. Plaque composition data are expressed relative to the percent of each component in plaques from MR-Intact animals. All comparisons were not significant (p > 0.05) by unpaired student's t-test. Scale bars = 200 μm.
