mortality/aging

embryo
• at E9.5 yolk sacs lack an organized vasculature and instead have blood filled patched cavities surrounded by endothelial cells
• about 85% fail to initiate turning by E9.5
• at E9.5
• kinked and undulated along the entire length at E8.5
• kinked and undulated along the entire length at E8.5
• embryos with failure of chorioallantoic fusion also have a swollen allantois
• failure of fusion in about 40%

cardiovascular system
• at E9.5 vessels appear enlarged especially in the head region; however, embryos are not hemorrhagic and cardiac development appears grossly normal
• at E9.5 yolk sacs lack an organized vasculature and instead have blood filled patched cavities surrounded by endothelial cells

homeostasis/metabolism
• at E8.5 effusions are seen in the head region and along the dorsal side of the embryo in 83% and 44% of embryos, respectively

nervous system
• at E9.5
• kinked and undulated along the entire length at E8.5
• kinked and undulated along the entire length at E8.5
• at E8.5 in more than 80% of embryos asymmetric enlargement of the neural headfolds is seen with the enlarged fold containing large cavities or effusions
