Blood supply, particularly of liver and placenta, is reduced in Juptm1Ruiz/Juptm1Ruiz mice at E12

mortality/aging
• death between E12 and E16, although a few survive to E16-E18; these are swollen and covered with edemas and have blood retention in kidney and liver

embryo
• evident beginning at E12
• spongiotrophoblast of the placenta is poorly supplied with blood
• spongiotrophoblast of the placenta is reduced in size

growth/size/body
• evident beginning at E12

cardiovascular system
• heart rupture in the ventricles
• morphology of intercalated discs is altered as they do not show differentiation of desmosomes and adherens junctions
• desmosomes of intercalated discs are absent by E8, however desmosomes are observed in various epithelia such as the epidermis
• blood supply, particularly of liver and placenta, is reduced
• pericardial cavities are frequently swollen and filled with blood
• amplitude of heart contraction is strongly reduced

muscle
• morphology of intercalated discs is altered as they do not show differentiation of desmosomes and adherens junctions
• desmosomes of intercalated discs are absent by E8, however desmosomes are observed in various epithelia such as the epidermis
• amplitude of heart contraction is strongly reduced

liver/biliary system
• at P14, liver parenchyme shows intital signs of deterioration

homeostasis/metabolism
• pericardial cavities are frequently swollen and filled with blood

integument
• pale due to decreased blood flow to liver and placenta

• mice exhibit normal lumbar motor column neuron specification, lateral migration, and segregation
• some motor neurons fail to migrate away from the ventricular zone unlike in control mice
• in the spinal cord medial motor column
• mice exhibit a 2.5-fold increase in En1+ V1 interneurons and 3-fold increase in Chx10+ V2a interneurons compared to in control mice
• mice exhibit a 3-fold increase in Chx10+ V2a interneurons compared to in control mice
• at E11.5, mice exhibit intermixing of medial and lateral lumbar motor column neurons unlike in control mice
• at E13.5, preganglionic column neurons are scattered in ectopic ventral position unlike in control mice
• mice exhibit disorganization of intrasegmental neuron pools compared with control mice
• however, organization of rostro-caudal neurons are normal
• Foxp1+ neurons are less densely packed than in control mice
• however, overall neuron packing is normal
