Title: [Differentiation antigens on normal bone marrow cells and following culture with growth factors in patients with acute myeloid leukemia (AML)].
Abstract: In an attempt to detect residual leukemic cells during complete remission (CR), we used 4 monoclonal antibodies detecting markers at different stages of myeloid maturation. Bone marrow cells of AML patients at diagnosis/relapse or in CR were compared with normal controls at day 0 and 7, after incubation with colony stimulating factors, by the alkaline phosphatase/antialkaline phosphatase method. In AML patients at diagnosis/relapse, the expression of the early differentiation markers (CD34, HLA DR) was significantly increased and that of the late marker CD15 significantly decreased at day 0. After day 7 liquid cultures, the markers HLA DR and CD13 were significantly increased and CD15 significantly decreased. During CR a significant increase in day 7 liquid cultures of the markers HLA DR and CD13 was found compared to normal controls. These results may reflect the proliferation in culture of residual leukemic cells in CR patients.
