| N | normal phenotype |
|
• die at E9.5
|
|
• embryos are slightly smaller at E7.5 and small at E8.5
|
|
• 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
|
|
• 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
|
|
• cell apoptosis is increased in E7.75 embryos
|
|
• cell proliferation is reduced in E7.75 embryos
|
|
• 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
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• half of the mutants show an anterior neural tube closure defect or exencephaly between E9.5 and E15.5
|
|
• half of the mutants show an anterior neural tube closure defect or exencephaly between E9.5 and E15.5
|
