mortality/aging
• homozygtes die in utero between day E3.5 and E7.5 due to arrested growth and expansion of the ICM of mutant blastocysts

cellular
• TUNEL analysis revealed enhanced apoptosis in the ICM
• TUNEL analysis indicates enhanced apoptosis in the ICM and in the giant trophoblast cells of mutant blastocyst outgrowths
• homozygotes display arrested growth and expansion of the ICM

• TUNEL analysis revealed enhanced apoptosis in the ICM
• homozygotes display arrested growth and expansion of the ICM
• blastocysts isolated from intercrosses of heterozygous mutant mice display degeneration of the ICM after 4 days in culture
• homozygotes exhibit trophoectoderm growth retardation
