Abnormal cardiac morphology, pericardial effusion, and growth retardation in Tmem100tm1.1Ysai and Acvrl1tm1Dgen homozygotes

mortality/aging

cardiovascular system
• at E9.5, one of the paired dorsal aortas often shows marked dilation with a narrowing or closure at the opposite end and clumps of blood cells are frequently seen in the caudal region
• expression analysis indicates defects in arterial differentiation and maturation
• mural layers surrounding the aorta are thinner at E9.5
• coarse vascular patterns indicative of impaired remodeling are seen at E9.5
• absence of large vessels at E10.5
• from the dorsal aorta towards the sinus venosus
• mural layers surrounding the myocardium are thinner at E9.5
• poorly formed at E9.5
• at E9.5
• massive pericardial effusion at E10.5
• decrease in vitelline circulation at E9.0 - E9.5

embryo
• absence of large vessels at E10.5
• detachment of endodermal and mesodermal layers at E9.5
• coarse vascular patterns indicative of impaired remodeling are seen at E9.5

growth/size/body
• at E9.5

homeostasis/metabolism
• massive pericardial effusion at E10.5

muscle
• poorly formed at E9.5
