embryo
• at E7.5 to E7.75, no embryonic derivatives were detected by marker expression unlike in wild-type mice
• as determined by marker expression
• the number of Oct4+ cells is reduced at E6.75 through E8.5 by apoptosis compared to in wild-type mice
• as determined by marker expression
• at E7.5 to E7.75, marker expression determined that extra-embryonic compartments are restricted to residual cells of extra-embryonic endoderm and derivatives of visceral ectoderm unlike in wild-type mice
• absent as determined by marker expression
