mortality/aging

embryonic lethality before implantation, complete penetrance ( J:168150 )

• embryos arrested at the blastocyst stage

• heterozygous intercrosses revealed no null embryos between E6.5 and E8.5

embryo

decreased inner cell mass proliferation ( J:168150 )

• in mutant embryos, both the TE and ICM lineages failed to expand normally between the morula and blastocyst stages

decreased trophectoderm cell proliferation ( J:168150 )

• in mutant embryos, both the TE and ICM lineages failed to expand normally between the morula and blastocyst stages

failure of blastocyst to hatch from the zona pellucida ( J:168150 )

• morulae cultured failed to hatch embryos and eventually collapsed

absent blastocoele ( J:168150 )

• the majority of E3.5 mutant embryos had either no cavity or a small cavity

cellular
