hematopoietic system
abnormal definitive hematopoiesis ( J:90463 )
• E11.5 aortic cells form significantly more macrophage and granulocyte colonies in culture
• culture of the aorta-gonad-mesonephros from homozygous embryos produces 3 fold more hematopoietic cells compared to wild-type
• about 2-fold more hematopoietic cell colonies are produced in bone marrow cell cultures from homozygous mice
increased megakaryocyte cell number ( J:90463 )
• increased numbers of megakaryocytes are seen in the spleens of homozygous mice
