mortality/aging
premature death ( J:148955 )
• more than 40% of mice die within the first 6 months of life

hematopoietic system
decreased common myeloid progenitor cell number ( J:148955 )
• the numbers of common myeloid progenitors, megakaryocyte-erythroid progenitors, and granulocyte-macrophage progenitors are decreased in the fetal livers compared to in wild-type mice
decreased immature B cell number ( J:148955 )
• decreased frequency in the bone marrow and spleen
decreased pro-B cell number ( J:148955 )
• the frequencies of pro/pre-B cells in the bone marrow compared to in wild-type mice
decreased pre-B cell number ( J:148955 )
• the frequencies of pro/pre-B cells in the bone marrow compared to in wild-type mice
abnormal hematopoietic stem cell morphology ( J:148955 )
• fetal liver cells exhibit reduced repopulation efficiency compared with wild-type cells
• embryoid bodies exhibit impaired onset of hematopoeitic lineages compared to wild-type embryoid bodies

decreased hematopoietic stem cell number ( J:148955 )
• at E14.5, the frequency of Lin-/Sca-1+/c-Kit+ hematopoietic stem cells in the liver is decreased compared to in wild-type mice

growth/size/body

abnormal hematopoietic stem cell morphology ( J:148955 )
• fetal liver cells exhibit reduced repopulation efficiency compared with wild-type cells
decreased hematopoietic stem cell number ( J:148955 )
