Nephrogenic rest in a Crl:CD (SD)IGS BR rat.
A nephrogenic rest was found in the kidney of an 11-week-old male Crl:CD (SD)IGS BR rat. Histologically, the rest was within the renal cortical interstitium and consisted of glomeruloid structures (primitive glomeruli) and inconsistently distinct basophilic tubules lined by a single layer of cuboidal to columnar cells and variably bordered by blastemal cells. Nephrogenic rests have not been reported previously in this rat strain.
