Representative photomicrographs of the renal cortex and medulla in normal Lewis rats using RECA-1 immunostaining (brown) showing the extensive peritubular and glomerular staining. (A) Renal cortex in Lewis rats at week 6 (100x) (B) Renal outer medulla in Lewis rats at week 6 (100x); (C) Renal inner medulla in Lewis rat at week 6 (100x). Arrows show examples of positive immunoreactivity for RECA-1 in the tubulointerstitium.
