hematopoietic system
abnormal erythropoiesis ( J:70036 )
• the numbers of erythroid burst-forming-units (BFU-E) are slightly reduced in fetal liver cell preparations relative to wild-type
• in adult bone marrow, the numbers of eryhtroid colony-forming-units (CFU-E) are increased 2-fold relative to wild-type
increased hematocrit ( J:70036 )
• embryos at E14.5, E15.5, and E18.5, and adults show slightly higher hematocrits than wild-type
• challenging mutants with continuous injections of Epo results in a greater increase in hematocrit than in wild-type or homozygous Eportm2Jni mutants
