immune system

abnormal B cell differentiation ( J:137738 )

• B cells develop inefficiently with a partial block occurring at the transition from pre- to pro- B cells

decreased immature B cell number ( J:137738 )

• B cells newly emerging from the bone marrow are at levels that are 30% of that in wild-type mice

increased late pro-B cell number ( J:137738 )

• late pro B-cells accumulate at numbers 3- fold higher than in wild-type at the fraction C (CD43⁺ CD45⁺ HSA^med BP-1⁺) step

decreased mature B cell number ( J:137738 )

• the levels of circulating mature B cells are 10% of the numbers found in wild-type

• these B cells express human mu heavy chain

decreased pre-B cell number ( J:137738 )

• pre-B cells numbers in the bone marrow are 70% of wild-type
