Immunophenotyping of leukemic cells in moribund IRF-4/8 DKO and IRF-4^+/−IRF-8^−/− mice. Cells isolated from ML, PB, BM, spleen (SP), and pleural effusion (PE) of moribund IRF-4/8 DKO (A) and IRF-4^+/−IRF-8^−/− (B) mice were analyzed by flow cytometry. Two-parameter dot plots show expression of lineage-specific antigens as indicated.
