General description

M-CSF is encoded by the gene mapped to human chromosome 1p13.3. It is a glycosylated polypeptide, which exists as a homodimer. M-CSF is produced by macrophage, fibroblasts, lymphocyte and endothelial cells.

Biochem/physiol Actions

Macrophage CSF (M-CSF) as a growth factor, stimulates the proliferation and differentiation of monocyte/macrophage-lineage cells. It also boosts antibody-dependent, cell-mediated cytotoxicity by monocytes and macrophages. In addition, human M-CSF inhibits bone resorption by osteoclasts. It might also play a crucial role in atherosclerosis. Overexpression of the gene has been observed in Paget’s disease of bone (PDB).

Analysis Note

The specific activity was determined by the dose-dependent stimulation of the proliferation of murine M-NFS-60 cells (mouse myeloid Leukemia indicator cell line).
