hematopoietic system
arrested B cell differentiation ( J:91091 )
• about 2 weeks after p(I)p(C) injections an almost complete block in B cell development is seen
decreased B cell number ( J:91091 )
• about 2 weeks after p(I)p(C) injections most of the B cells are lost from the spleen and lymph nodes
• marginal zone B cells were not affected probably as a result of replenishment from cells that escaped cre mediated recombination
absent immature B cells ( J:91091 )
• in the spleen almost all immature spleen cells are missing
