mortality/aging
|
• embryos are present at E9.5 but die by E10.5
|
embryo
|
• exhibit defects in angiogenesis of the yolk sac, with fewer and less well-developed vascular channels and reduced numbers of red blood cells in many embryos
|
|
• exhibit developmental delay of about 0.5 day, as indicated by a delay in fusion of the dorsal aorta
|
|
• exhibit defects in hematopoiesis of the yolk sac, with reduced numbers of blood cells in the yolk sac
|
cardiovascular system
|
• occasional embryos have a reduced cephalic capillary bed, however the appearance of the vasculature in the embryo (except for in the yolk sac) for the most part is normal
|
|
• exhibit defects in angiogenesis of the yolk sac, with fewer and less well-developed vascular channels and reduced numbers of red blood cells in many embryos
|
|
• almost all embryos have dilated outflow tracts
|
|
• the endothelial surface of the truncal cushions fails to organize in about half of homozygous embryos
|
|
• many embryos have abnormal cardiac looping
|
|
• almost all embryos have enlarged ventricles
|
