embryo

abnormal inner cell mass apoptosis ( J:93477 )

• increased apoptosis is seen in mutant blastocysts after overnight culture compared to wild-type

absent egg cylinders ( J:93477 )

• inability to form the egg cylinder in outgrowth assay

abnormal inner cell mass morphology ( J:93477 )

• in a blastocyst outgrowth assay the inner cellular mass is absent or degenerating and embryos fail to form the egg cylinder
