Effect of EPCs transplantation on renal morphology at 72 h following reperfusion. Renal sections were stained with hematoxylin and eosin and examined using light microscopy at a magnification ×400. A: Sham-operated rats exhibited minimal pathological changes in the kidneys. B: Following IRI, more severe lesions were observed in renal tubules, with tubular atrophy, dilatation, and intratubular casts, as well as congestion in the peritubular capillaries, massive epithelial cells and atrophic epithelial lining. C: EPCs suspension liquid caused a significant reduction in the severity of acute tubular necrosis. D: Degree of renal injury was clearly slighter than in the EPCs-treated group. E: Degree of renal injury was markedly slightest compared to rats subjected to IRI.
