title: Establishment of a macrophagelike cell line derived from U-937, human histiocytic lymphoma, grown serum-free.
abstract: A human macrophagelike cell line which grows in serum-free medium was established from a histiocytic lymphoma cell line, U-937. U-937 cells failed to differentiate into macrophagelike cells in serum-free medium plus 12-O-tetradecanoyl phorbol 13-acetate (TPA). Fibronectin and albumin in serum were necessary for differentiation of U-937 cells into macrophagelike cells in enriched RDF medium supplemented with insulin, transferrin, ethanolamine, selenite, egg yolk lipoprotein (eRDF-ITESL medium). The established cell line exhibited several characteristic properties of macrophage such as nitroblue tetrazolium reduction, phagocytic and alpha-naphthylbutyrate-esterase activities, and tumor necrosis factor and interleukin 1 production. At present the cells have been continuously maintained in eRDF-ITESL medium through over 150 passages.
