B cell development in wild-type and Syk-AQL mice. B cell development in wild-type and Syk-AQL mice. (A and B) Percentage of IgM+ (A) or IgD+ (B) lymphocytes present in mixed populations of splenocytes from wild-type (WT) versus Syk-AQL mice. Data represent means ± SEM for separate analyses of four mice. (C and D) An example of an analysis by flow cytometry comparing numbers of B220+IgM+ and IgM+IgD+ B cells present in a mixed splenocyte population isolated from a wild-type versus a Syk-AQL mouse.
