N normal phenotype
immune system
N
• the presence of the transgene prevents the arrest in B cell differentiation that occurs in Igh-Jtm1Jkbv homozygotes
• the levels of mature B cells found in the spleen are 50% and 70% respectively, of those found in wild-type mice
• these B cells express human mu heavy chain

hematopoietic system
• the levels of mature B cells found in the spleen are 50% and 70% respectively, of those found in wild-type mice
• these B cells express human mu heavy chain

hematopoietic system
• 25% to 35% of spleen cells express human mu heavy chain
• the proportion of spleen cells expressing endogenous mouse mu heavy chain is reduced from 50% in normal littermates to 5% to 15% in transgenic mice
• co-expression of the human transgene and endogenous murine mu heavy chain does not occur
