• the pontine nucleus develops normally

mortality/aging
premature death ( J:47671 )
• survival rates are lower than normal but higher than in Tcfe2a null mice

reproductive system

• less than 10% of B cell numbers are found in mice
• however, B cell commitment occurs normally
abnormal hematopoietic stem cell morphology ( J:47671 )
• hematopoietic stem cells fail to repopulate an irradiated mouse with B cells
• however, T cell development is normal

immune system
