Bone marrow samples obtained after informed consent from patients with acute leukemia were stained with anti-CD34-FITC and AC133-PE and were analyzed by multiparameter flow cytometry. Leukemic blasts expressing AC133 antigen were subdivided into AC133^dim (log fluorescence intensity between the first and the second decade) and AC133^bright cells (log fluorescence intensity between the second and the third decade).
