Background

M-CSF (macrophage colony stimulating factor, colony stimulating factor 1, CSF-1) is a hemtopoietic growth factor produced by monocytes, granulocytes, endothelial cells, fibroblasts and activated B-cells and T-cells. M-CSF stimulates macrophage colony formation and regulates proliferation and differentiation of hematopoeitic stem cells into macrophages and regulates survival and differentiation of monocytes. It enhances antibody-dependent cell-mediated cytotoxity, enhances marophage killing of tumor cells and microorganisms, regulates the release of cytokines and inhibits bone resorption by osteoclasts. Human M-CSF shows biological activity on murine and rat cells and although murine M-CSF is active in rat cells it is inactive in human cells.
