mortality/aging
• die between E13.5 and E14.5
(J:106927)
• mice die 1 to 2 days after developing edema
(J:130930)
|
cardiovascular system
• thin vascular smooth muscle walls are seen at E12.5 and E13.5 but not at E11.5 due to a decrease in vascular smooth muscle cell proliferation
|
• at E12.5 and E13.5, the compact zone is discontinuous
|
• myocardium has a disorganized structure and the chamber appears crowded
|
small heart
(
J:106927
)
• by E13.5, heart is about 2/3 the size of wild-type
|
• by E12.5, see a significant reduction in cell proliferation in the ventricles
|
homeostasis/metabolism
• onset of edema is at E12.5, associated with a distended fluid-filled thoracic cavity
|
• the edema formation rapidly progresses so that by E13.5, all embryos exhibit hydrops fetalis
|
lymphedema
(
J:130930
)
immune system
• at E13.5, the jugular lymph sac is smaller than in wild-type mice despite lymphedema
• proliferation of lymphatic endothelial cells is decreased compared to in wild-type mice
|
muscle
• thin vascular smooth muscle walls are seen at E12.5 and E13.5 but not at E11.5 due to a decrease in vascular smooth muscle cell proliferation
|
• at E12.5 and E13.5, the compact zone is discontinuous
|
• myocardium has a disorganized structure and the chamber appears crowded
|
• by E12.5, see a significant reduction in cell proliferation in the ventricles
|
• by E13.5, see a 6-fold increase in apoptosis throughout the heart, particularly in the ventricular apex, endocardial cushion, and septum
|
digestive/alimentary system
• onset of edema is at E12.5, associated with a distended fluid-filled thoracic cavity
|
integument
• distended skin is seen at E13.5, due to fluid accumulation in the interstitial space
|
cellular
• by E12.5, see a significant reduction in cell proliferation in the ventricles
|
• by E13.5, see a 6-fold increase in apoptosis throughout the heart, particularly in the ventricular apex, endocardial cushion, and septum
