hematopoietic system
• fewer granulocyte/monocyte progenitors but similar numbers of erythroid precursors compared to wild-type controls
|
• decrease in the number and percentage of LSK cells in the bone marrow of adults
• fewer long-term hematopoietic stem cells (Lin- Sca-1+ Kit+ Flk2- CD34-) in the bone marrow of adults
• when homozygous mutant mice are engrafted with wild-type bone marrow cells, fewer long-term hematopoietic stem cells are found in the reconstituted bone marrow indicating a non-cell autonomous phenotype
• when wild-type mice are engrafted with bone marrow cells from homozygous mutant mice no decrease in long-term hematopoietic stem cell numbers is seen
|
• decrease in the number and percentage of Lin- Mac-1+ CD4- stem cells in the fetal liver
