Abstract
Leukemic cells in the myeloblastic stage from a murine myeloid leukemia cell line (M1) were induced to differentiate to macrophages by lipopolysaccharide (LPS) from Gramโnegative bacteria. A granulocyteโmacrophage colonyโstimulating factor (CSF) was produced only during differentiation. After induction of differentiation, the continued presence of LPS was necessary to stimulate the macrophages to release CSF.
In contrast, a macrophage cell line (Mmโ1) derived from the M1 line produced CSF without LPSโstimulation, but CSF release was stimulated by the presence of LPS.
