mortality/aging
• the few surviving mice are born and die shortly thereafter
|
• most pups die at E14.5
|
• 15% of pups die by E10.5
|
nervous system
• at E9.5, cell proliferation in the neural tube is increased ventrally
• at E10.5, cell proliferation is increased relative to in wild-type mice ventrally and dorsally
• there is a greater than 2-fold increase in the ratio of proliferating neural progenitors to differentiated cells in the neural tubethere is a greater than 2-fold increase in the ratio of proliferating neural progenitors to differentiated cells in the neural tube
|
• at E9.25, pups possess neural tubes that have failed to close
|
• in 15% of pups
|
exencephaly
(
J:123924
)
• 15% of pups exhibit severe exencephaly accompanied by a wavy neural tube and a shortened anterior to posterior axis
• after E10.5, surviving pups exhibit complete exencephaly from the forebrain to the hindbrainafter E10.5, surviving pups exhibit complete exencephaly from the forebrain to the hindbrain
|
vision/eye
• at E 12.5 and E14.5, proliferation in the retina is increased while differentiation in decreased
|
• pups exhibit an outgrowth in the retinal epithelium
|
• pups exhibit an outgrowth in the neural retina
|
cellular
• the cell cycle length is decreased and there are defects in entering and exiting the cell cycle
|
embryo
• 15% of pups are shortened in the anterior to posterior direction
