A: representative renal cross sections (1 per animal from n = 7 per group) showing renal immunoreactivity and quantification of progenitor cell markers Oct-4, CD34, and stromal derived factor-1 (SDF-1) from normal, renal angioplasty, and stenting (PTRAs) and PTRAs+ elastin-like polypeptide-vascular endothelial growth factor (ELP-VEGF)-treated kidneys. B: coadjuvant intrarenal ELP-VEGF aministration during PTRAs improves stenotic kidney tubulointerstitial expression of progenitor cell recruitment molecules and markers of progenitor cells. Representative images captured at ×40 magnification. *P < 0.05 versus Normal. †P < 0.05 versus RVD+PTRAs.
