Peripheral blood leukemic cells are Lin^-/c-kit⁺ and GFP⁺. Representative examples of peripheral blood leukemic cell FACS analysis. FACS analysis of lineage markers (Gr1, B220, CD3, Ter119, and Mac1) and GFP, versus hematopoietic progenitor marker (c-kit) for wild-type (left column) and leukemic cells expressing either Cbfb-MYH11/Plag1 (middle column) or Cbfb-MYH11/PLAGL2 (right column).
