Hemorrhage in Rr249tm1.1Ebres/Rr249tm1.1Ebres embryos

mortality/aging

hematopoietic system
decreased common myeloid progenitor cell number ( J:191756 )
• from fetal liver hematopoietic precursors
decreased erythroid progenitor cell number ( J:191756 )
• from fetal liver hematopoietic precursors
decreased hematopoietic stem cell number ( J:191756 )
• severe depletion in the fetal liver at E12.5 and E13.5

cardiovascular system

• discontinuous endothelial cell barrier
hemorrhage ( J:191756 )
• severe at E13.5, including subcutaneous sites in the trunk and the brain
increased vascular permeability ( J:191756 )
• vascular integrity defect

liver/biliary system

homeostasis/metabolism
edema ( J:191756 )
• variable at E13.5

• from fetal liver hematopoietic precursors
decreased erythroid progenitor cell number ( J:191756 )
• from fetal liver hematopoietic precursors
decreased hematopoietic stem cell number ( J:191756 )
• intermediate depletion in the fetal liver at E12.5 and E13.5
• however, primitive hematopoietic stem/progenitor activity is unaffected
