hematopoietic system

decreased megakaryocyte cell number ( J:83262 )

• mutant mice displayed a loss of megakaryocytes in the bone marrow: a 10 fold drop in 32N Megakaryocytes and a 5 fold drop in 16N megakaryocytes

thrombocytopenia ( J:83262 )

• an 88% drop in platelet count was noted in homozygous animals

increased mean platelet volume ( J:83262 )

• a significant increase in the volume of remaining platelets was detected: mutant mice registered 8.7 cubic micrometers compared to 4.7 cubic micrometers in control animals; no significant differences were seen in red blood cells, total white blood cells, neutrophils, bands or esinophils from peripheral blood

immune system

immune system phenotype ( J:83262 )

N • size and cellularity of the lymphoid organs was unaffected
