A novel factor termed growth inhibitory (GI) factor, which specifically inhibits the growth of mouse monocytic leukemia cells including monocytic cell lines (Mm-A and J774.1) and other partially differentiated myeloid leukemic cells, has been purified from conditioned medium of some clones of mouse myeloblastic leukemia M1 cells. The procedure for purification of the GI factor included ammonium sulfate precipitation, CM-Sepharose CL-6B and Sephadex G-200 chromatographies, reverse-phase high-performance liquid chromatography on a C18 hydrophobic support, and high-performance liquid chromatography on a gel filtration column. The purified factor gave a single band of protein with a molecular weight of 25,000 on sodium dodecyl sulfate-polyacrylamide gel. A concentration of 8 X 10(-10) M GI factor was required for 50% inhibition of growth of Mm-A cells. On chromatofocusing, the GI activity was eluted with Polybuffer 96/acetic acid at pH 8.2-8.4. The purified GI factor markedly inhibited growth of mouse bone marrow cells stimulated by macrophage colony-stimulating factor. The GI factor appeared to be a unique cytokine unrelated to known cytokines such as the tumor necrosis factor, interferons, and oncostatin M.
