Abstract

The interactions of purified recombinant human leukemia inhibitory factor (LIF), interleukin‐6 (IL‐6), granulocyte colony stimulating factor (G‐CSF), and granulocyte‐macrophage CSF (GM‐CSF) on the clonogenicity of HL60 cells and U937 cells were studied in vitro. 11‐6 alone strongly suppressed colony formation by U937 cells with induction of differentiation and loss of clonogenicity. GM‐CSF interacted synergistically with IL‐6 to further reduce colony number and suppress the growth of clonogenic cells formed by HL60 and U937 cells. LIF synergized with IL‐6 to reduce colony number and enhance the suppression of the clonogenic U937 cells. The results suggest that these 4 glycoproteins, acting alone or in combination, may be able to suppress human leukemia cells of appropriate type and be of value in the clinical management of myeloid leukemia.

The human leukemic cell line AML-193 was tested for its proliferative response to endogenously produced autocrine factors and to a variety of cytokines and colony-stimulating factors. Cells grown in the absence of GM-CSF incorporated tritiated thymidine, and this was partially reversed by adding neu
