cardiovascular system
• small foci of intraparenchymal hemorrhages within the central nervous system are seen in some E11.5 embryos
• E12.5 embryos exhibit extensive hemorrhages within the vertebral canal
• hemorrhages appear to originate within the ganglia of the cranial nerves
• hemorrhages into the pericardial space, evident at E12.5
• hemorrhages into peritoneal cavity, evident at E12.5
• E12.5 embryos exhibit extensive hemorrhages within the ventricle of the central nervous system

nervous system
• E12.5 embryos exhibit extensive hemorrhages within the ventricle of the central nervous system

embryo
• mutants lack fetal liver hematopoiesis; no erythroid, myeloid, or megakaryocyte elements are seen in livers at E11.5-E12.5
• progenitors for definitive hematopoiesis of either erythroid or myeloid lineages are absent from the yolk sac and liver

hematopoietic system
• mutants lack fetal liver hematopoiesis; no erythroid, myeloid, or megakaryocyte elements are seen in livers at E11.5-E12.5
• progenitors for definitive hematopoiesis of either erythroid or myeloid lineages are absent from the yolk sac and liver

liver/biliary system
• slight pallor of the liver at E11.5

homeostasis/metabolism
• hemorrhages into the pericardial space, evident at E12.5
