mortality/aging

growth/size/body
• embryos are slightly smaller at E7.5 and small at E8.5

embryo
• cell apoptosis is increased in E7.75 embryos
• mutants fail to undergo embryonic turning at E8.75
• embryos are slightly smaller at E7.5 and small at E8.5
• an abnormal protrusion to the ventral side develops at the posterior end of the mutant embryo at E8.75, with abnormal cell accumulation in this region
• marker analysis indicates that development of the posterior definitive endoderm is partially compromised
• lateral plate mesoderm is displaced toward the lateral margins
• paraxial mesoderm is displaced toward the lateral margins
• the neural plate remains flat and the boundary between the neuroectoderm and the underlying mesoderm is not clearly demarcated
• neural plate is kinked dorso-ventrally at E8.75
• in the central region, the neural plate has not fused along the dorsal ridges to form a neural tube at E8.5
• marker analysis indicates defects in notochordal development
• E8.5 embryos lack a notochord
• no morphologically identifiable somites form
• embryos are highly disorganized at E9.5, and typically develop a posterior-ventral protrusion
• in the yolk sac, specification of both endothelia and erythroblasts occurs, but their development into an organized primitive vascular plexus is defective
• E9.5 embryos develop a bulbous allantois
• E9.5 embryos develop a bulbous allantois that fails to fuse with the chorion

cardiovascular system
• in the yolk sac, specification of both endothelia and erythroblasts occurs, but their development into an organized primitive vascular plexus is defective
• the anterior region is dorsally folded and there are two heart tubes at E8.5, indicating that the two heart primordia failed to fuse

cellular
• cell apoptosis is increased in E7.75 embryos
• cell proliferation is reduced in E7.75 embryos

nervous system
• the neural plate remains flat and the boundary between the neuroectoderm and the underlying mesoderm is not clearly demarcated
• neural plate is kinked dorso-ventrally at E8.75
• in the central region, the neural plate has not fused along the dorsal ridges to form a neural tube at E8.5
