Lymphokine-activated killer (LAK) cells were generated successfully without mitogen from blood mononuclear cells obtained from 14 patients with varying malignancies and 2 normal donors. Cells from both groups showed a positive cytotoxicity by a 4-hour 51-Cr-release assay against a variety of target cells including natural killer (NK) sensitive K562 myeloid leukemia, NK-resistant Raji lymphoma cell lines, and fresh/cryopreserved leukemia cells from patients refractory to standard chemotherapy but not normal blood cells. Higher cytotoxic activity was obtained with a higher effector:target ratio at 100:1 greater than 50:1 greater than 25:1 (P less than 0.01) in each setting of different targets. Experiments involving cocultures of the LAK cells with either allogeneic (9) or autologous (3) bone marrow cells disclosed no detrimental effect on the committed hemopoietic stem cells by semisolid agar colony forming unit (CFU-GM) assay. The findings suggest that LAK cells may have a potential role for the in vitro purging of the residual leukemic cells from the marrow inoculum prepared for autologous bone marrow transplantation.
