mortality/aging
• fewer than expected mice are present between E15.5 and E17.5 with no mice detected at E18.5
|
nervous system
• in the neuroepithelium at E9.5 but not E8.5
|
• increased cellular numbers in the hindbrain
• increased thickness in the mid- and forebrain
|
• at E9.5, mice exhibit large open anterior neural tube encompassing the mid and hindbrain with some extension into the forebrain region
• mice exhibit a failure of the dorsolateral hinge formation and neural tube closure with collapse of the neural fold by E10.5
|
• severe
• however, anterior-posterior patterning is normal
|
exencephaly
(
J:232516
)
• in hindbrains at E13.5
|
• at E8.5 but not E9.5
|
embryo
• abnormal embryo at E9.5
• however, mice are normal at E7.5
|
• increased cellular numbers in the hindbrain
• increased thickness in the mid- and forebrain
|
• at E9.5, mice exhibit large open anterior neural tube encompassing the mid and hindbrain with some extension into the forebrain region
• mice exhibit a failure of the dorsolateral hinge formation and neural tube closure with collapse of the neural fold by E10.5
