Figure 2. MD2 deficiency alleviated Ang II induced vascular remodeling in vivo. (A) Aortic thickening in the mice and aortic tunica media fibrosis was examined by Masson trichrome staining and H&E staining (scale bar = 50 μm). (B) Quantification for staining results in 2A (n = 10; ***p<0.001 compared to Vehicle; ###p<0.001 compared to Ang II). (C) Representative immunofluorescence staining images for α-SMA (green) and Vimentin (red) in aortas. Tissues were counterstained with DAPI (blue) (scale bar = 50 μm). (D, E) Quantification for staining results in 2C (n = 10; ***p<0.001 compared to Vehicle; ##p<0.01 compared to Ang II). (F) Representative images of COL-3 and PCNA staining of aortas (scale bar = 500 μm; DAB chromogen staining (brown). (G, H) Quantification for staining results in 2F (n = 10; ***p<0.001 compared to Vehicle; ##p<0.01 compared to Ang II). (I, J) Expressions of α-SMA, Vimentin and COL-3 in the whole aorta (n = 10; *p<0.05, **p<0.01 compared to Vehicle; ##p<0.01 compared to Ang II).
