Tmsb4xtm1Prri mutation (2 available); any Tmsb4x mutation (12 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• fewer than expected mice are recovered between E10.5 and E14.5

cardiovascular system
• reduce mural cell coverage in the dorsal aorta subdermal vessels at E10.5
• mice exhibit impaired differentiation of mural cells from mesoderm
• however, mural cell apoptosis, proliferation and coverage in the retina derived from migration is normal
• mice lack defined coronary arterioles
• at E14.5, vascular smooth muscle cells abnormally reside in the epicardial layer and reduced presence in the underlying myocardium compared to in wild-type mice
• sparse and disrupted
• in the coelomic cavity in some mice at E10.5
• severity varies based on reduced mural coverage
• however, some mice recover by E14.5
• in some mice at E10.5
• in some mice at E10.5
• in some mice at E10.5

muscle
• at E14.5, vascular smooth muscle cells abnormally reside in the epicardial layer and reduced presence in the underlying myocardium compared to in wild-type mice
• sparse and disrupted

nervous system
• in some mice at E10.5

homeostasis/metabolism
• in some mice at E10.5

vision/eye
N
• P6 retina exhibit normal mural cell coverage
