mortality/aging
• by E11.5 and E12.5, approximately 50 and 100% of mice die, respectively

cardiovascular system
• cranial blood vessels fail to undergo remodeling events
• decreased vascularization with fewer fetal blood vessels invading
• cranial blood vessels fail to undergo remodeling events
• at E11.5 about 50% of embryos are necrotic with no intact vascular structures
• intersomitic vessels form but are unable to organize or full infiltrate the somites, displaying significant decreases in vessel length and branch points
• impaired vascularization of the tail with the formation of truncated and disorganized networks
• decrease in the number of mesenchymal cells in the atrioventricular canal

embryo
• decreased vascularization with fewer fetal blood vessels invading
• at E10.5 and E11.5 crown to rump length is decreased by 32 and 47%, respectively, compared to control littermates
• severely defective remodeling of the primary vascular plexus at E10.5

growth/size/body
• at E10.5 and E11.5 crown to rump length is decreased by 32 and 47%, respectively, compared to control littermates

nervous system
• cranial blood vessels fail to undergo remodeling events
