growth/size/body
• body size is significantly reduced at E13.5 and E14.5
|
• at E13.5 and E14.5, compound heterozygotes are developmentally delayed by 1 day relative to wild-type controls, as noted by eye pigmentation and limb development
|
limbs/digits/tail
• at E14.5, limb development is delayed relative to that in wild-type controls
|
nervous system
N |
• although cortical thickness, number of TBR2+ intermediate neural progenitors, and thickness of the TUJ1+ neuronal layer are reduced at E14.5, these differences are largely due to developmental delay, as E14.5 values are similar to those in E13.5 wild-type brains
• no significant apoptosis is noted in the cortex at E14.5
