A: microcomputed tomography images of renal microvessels in sham, RAS, RAS+PTRA, and RAS+PTRA+EPC. The vascular density was estimated in outer strip of medulla (highlighted) in all groups. Medullary densities of vessels with diameters smaller than 100 μm were decreased in all groups compared with sham (B), as was capillary density estimated from histology (C). Values are means ± SE. *P < 0.05 vs. sham.
