hematopoietic system
• B cell development is almost exclusively restricted to the generation of B-1 cells
• mutant mice display a higher percentage of pro-B cells (CD19+CD43+) in the bone marrow relative to wild-type controls
• mutant mice display an increase in the number of B cells in spleen (4-fold), lymph nodes (2-fold) and peritoneal cavity (2-fold) relative to age-matched wild-type controls
• >90% of peripheral mutant B cells exhibit a B-1 cell phenotype (CD24intCD38hi)
• no follicular and marginal zone B cells are identified, as most splenic B cells are CD5intCD21loCD23lo
