The activation of human peripheral blood mononuclear cells (PBM) in culture leads to the generation of nonspecific killer cells. These cells, termed activated lymphocyte killer (ALK) cells, can kill fresh tumor cells and tumor cell lines, in addition to the natural killer (NK) cell sensitive target K562. ALK cells have features in common with both T and NK cells, but their nature and origin are unknown. In the present study, it is shown that ALK cells are in fact heterogeneous and can be generated from both large granular lymphocytes with the same phenotype as NK cells and from T cells. Cell populations enriched for NK cells, when cultured with lymphokines, rapidly acquired a T cell phenotyp..
