Immunophenotype of cells from the bone marrow and peripheral blood of FLT3-ITD mice. Flow cytometric analysis of bone marrow (BM) and peripheral blood (PB) cells from mice that received a transplant of bone marrow transduced with (A) low- or (B) high-expressed FLT3-ITD. Two-parameter dot plots show expression of lineage-specific antigens (CD11b, Gr-1, B-220, Thy1.2) versus EGFP. Numbers indicate the percentage of cells in each quadrant.
