title: Autocrine growth of murine lymphoma cells.
abstract: By using an assay system in which small numbers of murine T lymphoma cells are stimulated to grow in serum-free medium, we have continued and expanded our previous studies of an autocrine growth factor that we call leukemia-derived growth factor (LDGF). We show that a T lymphoma cell line of immature phenotype, adapted to growth in serum-free medium, produces and responds to LDGF. LDGF activity is distinct from activities of 10 highly purified or recombinant hematopoietic growth factors including IL-1 and IL-2. However, growth-stimulating activity for the murine lymphoma cells is provided by a partially purified human LDGF.
