Cherpem1(IMPC)J/Cherpem1(IMPC)J mice exhibit embryonic lethality, with embryos recovered at E3.5 but not at E7.5. Embryos show abnormal morula morphology. Blastocysts grown in vitro hatch from the zona pellucida but outgrowths show no defined inner call mass and few trophectoderm cells.

embryo
abnormal inner cell mass morphology ( J:279207 )
• in vitro outgrowth assays show no defined inner cell mass (ICM) after 3 days in culture
abnormal trophectoderm morphology ( J:279207 )
• in vitro, few trophectoderm (TE) cells are observed after 3 days in culture
abnormal morula morphology ( J:279207 )
• some embryos recovered at E3.5 appear as irregular morulae

mortality/aging
embryonic lethality prior to organogenesis, complete penetrance ( J:279207 )
• homozygous embryos are recovered at expected Mendelian ratios at E3.5 but appear as irregular morulae or early blastocysts; no homozygous embryos are recovered at E7.5
• however, excess resorption sites suggest that embryos elicit a decidual response in vivo

reproductive system
abnormal embryo implantation ( J:279207 )
• in vitro, blastocysts hatch from the zona pellucida but form outgrowths with no defined ICM and few trophectoderm cells after 3 days in culture
