B-cell lymphoma phenotypes in IgH-c-myc transgenic mice. (A) A typical flow cytometry analysis for B-cell lymphoma phenotyping. One representative experiment for a B220⁺CD19⁺IgM⁺IgD⁺CD43⁻CD117⁻CD138⁻ B-cell lymphoma is shown. (B) Percentage of mature (IgM⁺IgD⁺) and immature (IgM^+/−IgD⁻) B-cell lymphomas (24 c-myc-KIE_μ, 19 c-myc-KIC_μ, and 37 c-myc-KIC_α mice). (C) Percentages of CD138⁺ mature B-cell lymphomas in c-myc-KIE_μ, c-myc-KIC_μ, and c-myc-KIC_α mice. The number (n) of mice for each group is indicated. (D) Percentages of CD19⁻ mature B-cell lymphomas in c-myc-KIE_μ, c-myc-KIC_μ, and c-myc-KIC_α mice. Same mice as in panel C.
