Arrested development and abnormal morphogenesis of extraembryonic tissues in Ctdnep1tm1Ryn/Ctdnep1tm1Ryn embryos

mortality/aging
embryonic lethality during organogenesis, complete penetrance ( J:199855 )
• no viable mice are recovered at E11.5

• despite being present in Mendelian ratios at E7.5, only a few poorly developed mice are recovered at E9.5

reproductive system
abnormal primordial germ cell morphology ( J:199855 )
• AP+ cells fail to transit from mesoderm to the endoderm

embryo
abnormal embryonic tissue morphology ( J:199855 )
• poorly developed head fold and trunk at E8.25
abnormal head fold morphology ( J:199855 )
