Flow cytometric analyses of various leukemic cells. (A) Hematopoietic lineage marker expression was analyzed in leukemic cells expressing AE9a-delNHR1 or AE9a-del(350-428) (EGFP+). (B) Analyses of surface myeloid progenitor marker expression in AE9a, AE9a-delNHR1, or AE9a-del(350-428) leukemic cells. Data represent the results from analyses of 4 samples of each leukemogenic construct.
