Summary: We report a transgenic mouse line that expresses Cre recombinase exclusively in podocytes. Twenty‐ four transgenic founders were generated in which Cre recombinase was placed under the regulation of a 2.5‐kb fragment of the human NPHS2 promoter. Previously, this fragment was shown to drive beta‐galactosidase (β‐gal) expression exclusively in podocytes of transgenic mice. For analysis, founder mice were bred with ROSA26 mice, a reporter line that expresses β‐gal in cells that undergo Cre recombination. Eight of 24 founder lines were found to express β‐gal exclusively in the kidney. Histological analysis of the kidneys showed that β‐gal expression was confined to podocytes. Cre recombination occurred during the capillary loop stage in glomerular development. No evidence for Cre recombination was detected in any of 14 other tissues examined. genesis 35:39–42, 2003. © 2002 Wiley‐Liss, Inc.
