Histological analysis of the degree of aneurysmal fibrosis with Masson's Trichrome staining at 6 weeks after periaortic application of CaCl2, showing increased medial fibrosis in the AAA of control diet group compared to the EPA diet group. In general, there was no difference in adventitial fibrosis between the two groups. Connective tissue (e.g. collagen) stain blue while muscle cells stain red. Scale bars, 200 µm (upper panels) and 50 µm (lower panels). Images are representative of at least three independent experiments. <b>Figure S2.</b> Gating strategy for the flow cytometric analysis of aortic macrophages. Living cells isolated from aortic tissues were first gated on Ly-6G (granulocyte marker), and Ly-6G<sup>−</sup> cells were further analyzed for expression of Ly-6C and CD11b (<b>A</b>); Ly-6C<sup>low</sup>CD11b<sup>+</sup> cells were shown to be positive for F4/80, a macrophage marker (<b>B</b>), and Ly-6C<sup>low</sup>CD11b<sup>+</sup>F4/80<sup>+</sup> cells were taken to be aortic macrophages and used in all subsequent analyses. <b>C</b>. Giemsa staining of sorted Ly-6C<sup>low</sup>CD11b<sup>+</sup>F4/80<sup>+</sup> cells from the aorta shows cells with the characteristic macrophage appearance. Scale bar, 10 µm. <b>Figure S3</b>. Stimulation of vascular SMCs with osteogenic cocktail induces the expression of osteogenic and tissue remodeling factors. Rat primary vascular SMCs were stimulated with an osteogenic cocktail (OC) for 7 days. Expression of the osteogenic factor <i>Tnfsf11</i> (RANKL) and tissue remodeling factors <i>Mmp2</i> and <i>Mmp9</i> were analyzed using real-time PCR. <i>n</i> = 3 per condition. *<i>P</i><0.05.</p> <p>(PDF)</p> 2014-05-05 03:30:16 anatomy Cardiovascular anatomy Biochemistry lipids Fatty acids cell biology Cellular types Animal cells Blood cells White blood cells monocytes Immune cells immunology cardiology Cardiovascular diseases Valvular diseases Diagnostic medicine Diagnostic radiology tomography Computed axial tomography Radiology and imaging Vascular medicine Aortic diseases Model organisms Animal models Mouse models polyunsaturated fatty eicosapentaenoic attenuates abdominal aortic aneurysm suppression
