Fig. 7.

Representative renal histology from direct/ipsilateral and remote/contralateral injured kidneys following reduction in renal mass by UNx and exposure to elevated dietary salt. Shown are representative PAS-stained sections of a kidney from a sham-operated animal at day 63 (A), a remotely injured kidney (B), and a directly injured kidney (C). Magnification is shown in C. Insets for each micrograph reveal the presence of interstitial infiltrate in remotely injured kidneys and a more severe infiltration in directly injured kidneys.
