Cyc1em1(IMPC)Bay/Cyc1em1(IMPC)Bay mice exhibit embryonic lethality, with embryos recovered at E7.5 but not at E9.5. Embryos are smaller, show severe developmental delay, forming an epithelium with no obvious embryonic-extraembryonic boundary and abnormal epiblast.

mortality/aging
• homozygous embryos are present at E7.5 (6% versus expected 25%, n=58), but not recovered at E9.5

embryo
• embryos show a severe developmental delay at E7.5
• embryos are much smaller than controls at E7.5
• a few Pou5f1/Oct4-positive cells are detected at E7.5
• embryos form an epithelium with no obvious embryonic or extraembryonic boundary

growth/size/body
• embryos show a severe developmental delay at E7.5
• embryos are much smaller than controls at E7.5
