cardiovascular system
|
• primary endothelial cells exhibit less robust migration in a Boyden chamber migration assay and do not respond to Sema3A unlike wild-type cells
• aortic rings fail to exhibit a response to Sema3A unlike wild-type cells
|
skeleton
|
• poorly formed and frequently fused or split in the lumbar and thoracic regions
|
|
• frequently fused in the lumbar and thoracic regions
• in the one mouse that survives into adulthood, vertebral bodies are fused along the entire anterior-posterior axis

mortality/aging
|
• all homozygous mutants become cyanotic and die within 24 hours of birth
|
cardiovascular system
|
• at E10.5 the 4th arch arteries are reduced in size
|
|
• at E10.5, the 6th arch arteries are extremely small or absent
• a mass of endothelial cells that fail to form a tube are seen near where the 6th arch arteries should be located
|
|
• the right subclavian artery arises from a more distal location than normal
|
|
• some embryos display right-sided aortic arch
|
|
• the origin of the coronary artery is ectopic arising from the mid portion of the ascending aorta rather than from the coronary sinus
|
|
• the left subclavian artery is closed or absent
|
|
• at E10.5 the intersomitic vasculature is disorganized with vessels crossing the out of the regions between somites
• this disorganization results in abnormal intercostal vessels in homozygous mutant neonates however the abnormalities are not as severe suggesting partial recovery occurs
|
|
• increased vascularity is seen on the surface of the ventricles
|
|
• the ductus arteriosus is absent
|
|
• the number of differentiated smooth muscle cells surrounding the 4 th and 6th arch arteries is reduced
|
|
• failure of septation of the cardiac outflow tract is seen at E12.5 and at birth
|
|
• the atria are thin-walled
|
homeostasis/metabolism
muscle
|
• the number of differentiated smooth muscle cells surrounding the 4 th and 6th arch arteries is reduced

|
• at E10.5 the 4th arch arteries are reduced in size

• at E10.5, the 6th arch arteries are extremely small or absent
• a mass of endothelial cells that fail to form a tube are seen near where the 6th arch arteries should be located
