immune system
• thymocyte number is decreased 100-fold compared to wild-type and heterozygous mice
• B cell development is blocked at B220+ IgM- pre-/pro-B cell stage
• only DN thymocytes are detected
• only double-negative (DN) thymocytes are detected; developmental block occurs at CD44-CD25+ DN stage
• B cell number in bone marrow is decreased by ~half
• only a fraction of cells in Peyer's patches express Rag2 amongst peripheral lymphoid organs; these T cells are of thymic origin

hematopoietic system
• thymocyte number is decreased 100-fold compared to wild-type and heterozygous mice
• B cell development is blocked at B220+ IgM- pre-/pro-B cell stage
• only DN thymocytes are detected
• only double-negative (DN) thymocytes are detected; developmental block occurs at CD44-CD25+ DN stage
