Endothelial cell (EC) calreticulin (Calr) Δ/Δ resistance arteries are not morphologically different young or aged. A: representative trichrome collagen staining of third order mesenteric artery cross sections. Scale bar = 25 μm in each image. B: the number of internal elastic lamina (IEL) holes were quantified in 4 distinct regions of an en face 3rd-order mesenteric artery. Aging significantly decreased the number of IEL holes with no genotype effect (n = 4 arteries from 4 mice/group; **P < 0.01 via two-way ANOVA with post hoc test).
