Mouse myeloid leukemia M1 cells were induced to differentiate in vitro into macrophages and granulocytes by various inducers including ascitic fluid. Differentiated M1 cells induced with ascitic fluid expressed a differentiation-associated cell surface glycoprotein with a molecular weight of 180,000 (p180), which can be labeled by lactoperoxidase-catalyzed radioiodination or metabolic labeling with L-[14C]fucose. p180 was also induced by treatment with conditioned medium of hamster embryo cells, dexamethasone, dibutyryl cyclic adenosine 3':5'-monophosphate, and prostaglandin E1. Ascitic fluid, conditioned medium of hamster embryo cells, and dexamethasone induced all the differentiation-associated properties tested, whereas dibutyryl cyclic adenosine 3':5'-monophosphate and prostaglandin E1 induced lysozyme activity and adhesiveness to the substratum but not phagocytosis, locomotive activity, Fc receptors, or morphological changes. The adherent cells induced by dibutyryl cyclic adenosine 3':5'-monophosphate produced a large amount of p180, while the floating cells produced very little, but no difference was detected in the lysozyme activities of the two cell types. These results suggest that p180 is associated with cell-substratum adhesion of differentiated M1 cells.
