  • Title: Flow cytometric analysis of peroxidase negative acute leukemias by monoclonal antibodies--II. Acute megakaryoblastic and acute pro-megakaryocytic leukemias.
    Author: Imamura N, Kajihara H, Kuramoto A.
    Journal: Leuk Res; 1988; 12(4):279-89. PubMed ID: 3163741.
    Abstract:
    In this report, we have described three cases of acute megakaryoblastic leukemia (AMKL) which were demonstrated by the presence of megakaryocyte-platelet-related cell-surface antigens detected by utilizing flow cytometry and monoclonal antibodies in addition to both PPO activity which was shown by ultrastructural cytochemistry and emergence of differentiation antigens while culturing these leukemic cells. The blasts of one case possessed both platelet GpIb and GpIIb/IIIa cell-surface antigens detected by 5F1 (CD36), AN51 (CDw42), and J15, P2 and HPL2 (CDw41), respectively, whereas the remaining two cases almost completely lacked Gp1b cell-surface antigen. Hence, the former was diagnosed as immature (pro) megakaryocytic leukemia and the latter as AMKL from the viewpoint of immunophenotypic analysis as discussed in this article.
