hematopoietic system
abnormal hemoglobin ( J:15268 )
• hemoglobin levels are decreased due to reduced cell volume without any increase in cell numbers
decreased mean corpuscular volume ( J:15268 )
• mean cell volume of erythrocytes is significantly smaller than controls
abnormal mast cell physiology ( J:14715 , J:15259 )
• proliferative response of bone marrow mast cells to Il-3 stimulation was severely impaired (J:14715)
• apoptosis occurs more slowly on removal of Il-3 from bone marrow mast cells in culture than from wild-type cells (J:15259)

growth/size/body
decreased birth body size ( J:91592 )
• neonates are smaller compared to wild-type and littermates that are not homozygous for at least one of the loci
postnatal growth retardation ( J:91592 )
• mutants are about 30% smaller compared to wild-type and littermates that are not homozygous at at least one of the loci
• all organs, except for the thymus, are decreased in size in proportion to the reduced body size as a result of a decrease in cell number

hematopoietic system
decreased B cell proliferation ( J:91592 )
• B cell proliferation in response to IL-7 is significantly impaired in the bone marrow
decreased T cell proliferation ( J:91592 )
• T cell proliferation is reduced in response to suboptimal levels of alphaCD3 and IL2
increased early pro-B cell number ( J:91592 )
• the fraction of pre-pro-B cells is increased in the bone marrow
decreased pro-B cell number ( J:91592 )
• the fraction of late pro-B cells is slightly decreased
decreased megakaryocyte cell number ( J:91592 )
• fewer and hypoproliferative megakaryocytes are seen in spleen sections
abnormal proerythroblast morphology ( J:91592 )
• the erythroid progenitor fraction in the spleen is increased
increased erythrocyte cell number ( J:91592 )
• a slight increase in erythrocyte numbers is seen without an increase in hematocrit
• the number of mature erthrocytes is also increased in the spleen
decreased mean corpuscular volume ( J:91592 )
• mean erythrocyte cell volume is decreased
decreased B cell number ( J:91592 )
• the fraction of splenic B cell is reduced about 25% at 8 weeks but returns to normal by 20 weeks
decreased pre-B cell number ( J:91592 )
• the fraction of pre-B cells especially of late pre-B cells is decreased in the bone marrow

immune system
decreased B cell proliferation ( J:91592 )
• B cell proliferation in response to IL-7 is significantly impaired in the bone marrow
decreased T cell proliferation ( J:91592 )
• T cell proliferation is reduced in response to suboptimal levels of alphaCD3 and IL2

cellular
decreased B cell proliferation ( J:91592 )
