Analysis of myeloid progenitors in bone marrow and spleen of APL-diseased KPM+, KM+, nondiseased KP+, and control M+ (pI-pC treated Mx1-Cre) mice. Quadrants represent the gated populations of myeloid progenitors (IL-7Rα-Lin-Sca1-c-Kit+), CMPs (FcγRloCD34+), GMPs (FcγRhiCD34+), and MEPs (FcγRloCD34-), whose percentages relative to whole bone marrow and spleen are indicated.
