Detailed Description

The Ret^- allele (also called ret-k^-, ret-k minus, or c-ret^-) disrupts the region of the ret proto-oncogene (Ret; also called ret-k or c-ret) locus harboring the invariant lysine codon required for Ret kinase activity. Homozygous mice die around 16-24 hours after birth, exhibiting abnormalities in kidney/urinary (renal agenesis/hypodysplasia) and peripheral nervous system development (including sympathetic, parasympathetic, and enteric ganglia), as well as abnormal enteric neural crest cell migration. Because homozygous mice lack enteric ganglia from the hindgut, these mice are also a model of Hirschsprung's Disease.

Development

A targeting vector was designed to replace an 0.8 kb region of the ret proto-oncogene (Ret; also called ret-k or c-ret) locus, including the codon for an invariant lysine required for Ret kinase activity, with a neomycin resistance cassette. The construct was electroporated into 129S/SvEv-Gpi1^c derived CCE embryonic stem (ES) cells. Correctly targeted ES cells were injected into recipient blastocysts and chimeric mice were bred with 129/SvEv mice to establish the colony. Heterozygous mice were bred with wildtype 129/SvEv (and/or 129S6/SvEvTac) mice for many generations prior to sending to The Jackson Laboratory Repository. Upon arrival, mice were bred together 129S1/SvImJ inbred mice (Stock No. 002448) for at least one generation to establish the colony.
