title: Establishment and characterization of a new human cloned myelomonocytic cell line (ZC-1.6).
abstract: A human cell line, ZC, derived from the blood of a patient with acute myelomonocytic leukemia, was established and cloned. One of the clones, ZC-1.6, was subsequently characterized. As for its morphology and cytochemistry, ZC-1.6 clone shares a number of features with immature cells of the monocytic or myelocytic lineages. Surface marker analysis shows positivity for 4F2 (100% of the cells), and OKM1 (38%) monoclonal antibodies, and presence of surface HLA-D/DR antigens (100%) and Fc (11%) and complement (C3b) receptors (100%). Functional capabilities of ZC-1.6 cells include adherence, spreading, and phagocytosis of latex and opsonized zymosan particles. Despite its morphological immaturity, the ZC-1.6 clone produces relevant amounts of O2- in the presence of different stimuli (phorbol myristate acetate, opsonized zymosan, or latex particles). The production of O2- by ZC-1.6 cells is the first evidence that reactive oxygen intermediate production may represent an early feature of cells of the myelomonocytic lineage.
