Fig 1: Histology of the mesenteric arteries in Nppb−/− at 4 and 9 months.(A) H&E analysis of progressive mesenteric arterial lesions in Nppb−/− . Mesenteric tissues obtained from animals of early and late symptom onset; 4 and 9 months in Nppb−/− vs 9 month Nppb+/+ (Control arteries highlighted by white arrows). (B) Factors involved in Nppb−/− mesenteric arterial remodeling: representative immunofluorescent microphotographs from 9 month Nppb−/− (n = 4), 4 month Nppb−/− (n = 3), and 9 month Nppb+/+(n = 3) sections, out of an average of 5 images per animal/section of mesenteric sections are shown. Specific antibodies include anti-Fgf2 (red), anti-Desmin (red), anti-α-SMA (green), anti-IL6 (green), anti-IL8 (green), and anti-CD45 (blue). Nuclei were counterstained by DAPI (white).
