mortality/aging
• generalized developmental arrest after E9.5
• no embryos survived beyond day E11

cardiovascular system
• loss of alpha-Sma staining in arteries of these mice indicates a failure to recruit arterial smooth muscle cells
• narrowing of the rostral dorsal aorta was observed in E8.5 embryos
• intersomitic arteries become dilated shortly after their formation between E8.5 and E9.0
• narrowing of the branchial arteries was observed in E8.5 embryos
• dilation occurred throughout the aorta just distal to the heart and extend to most caudal regions of the E8.5 embryo
• abnormal vascular dilation noted at E8.5
• vascular dilation was associated with an increased endothelial proliferation rate
• no difference in vascular apoptosis was observed
• no enlargement of the cardinal veins was observed
• no evidence of arteriovenous shunts
• cardiac development is normal prior to the development of vascular defects

embryo
• narrowing of the branchial arteries was observed in E8.5 embryos
• generalized developmental arrest after E9.5
• embryos retained a primitive yolk sac vascular network

craniofacial
• narrowing of the branchial arteries was observed in E8.5 embryos
