Gspt1em1(IMPC)Bay/Gspt1em1(IMPC)Bay mice exhibit embryonic lethality, with embryos recovered at E3.5 as blastocysts but not at E7.5. Blastocysts in vitro hatch from the zona pellucida and form irregular outgrowths.

mortality/aging
embryonic lethality between implantation and somite formation, complete penetrance ( J:279207 )
• blastocyst-like embryos are present at E3.5 (14% versus expected 25%, n=28); 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 irregular outgrowths after 3 days in culture
