embryo
increased allantois apoptosis ( J:78546 )
• although embryos exhibit fusion of the allantois with the chrion by E8.5, there is a significant increase in apoptotic cells
embryo tissue necrosis ( J:78546 )
• see many necrotic cells in the neuroepithelium of the brain by E11.5 and lysis of head and trunk mesenchyme tissue
abnormal paraxial mesoderm morphology ( J:78546 )
• the neuroepithelial mesenchyme has sparse cells
abnormal embryonic neuroepithelium morphology ( J:78546 )
• the neuroepithelium has sparse cells
abnormal chorion morphology ( J:78546 )
• at E8.5, the chorion is organized as a chorionic plate and lacks fetal blood vessels
abnormal spongiotrophoblast layer morphology ( J:78546 )
• by E9.5, the spongiotrophoblast layer remains significantly underdeveloped
abnormal placenta labyrinth morphology ( J:78546 )
• by E9.5, the labyrinthine layer remains significantly underdeveloped
small placenta ( J:78546 )
• by E9.5, the placenta is less than half the normal size

nervous system
abnormal embryonic neuroepithelium morphology ( J:78546 )
• the neuroepithelium has sparse cells

cardiovascular system
abnormal blood vessel morphology ( J:78546 )
• embryos exhibit dilated blood vessels
abnormal heart morphology ( J:78546 )
• exhibit apoptotic cells in the heart
hemorrhage ( J:78546 )
• exhibit widespread hemorrhages in all organs by E11.5

cellular
increased allantois apoptosis ( J:78546 )
• although embryos exhibit fusion of the allantois with the chrion by E8.5, there is a significant increase in apoptotic cells
embryo tissue necrosis ( J:78546 )
• see many necrotic cells in the neuroepithelium of the brain by E11.5 and lysis of head and trunk mesenchyme tissue
paternal imprinting ( J:78546 )
• all defects are seen in F2 heterozygotes that receive the mutant allele from the mother, while all F1 heterozygotes that receive the mutant allele from the father are normal
