| Target Function | Macrophage Colony-stimulating Factor (M-CSF), also known as CSF-1, is a cytokine with roles in the growth, differentiation, and survival of monocytes and macrophages. M-CSF promotes the differentiation of monocytes into mature tissue-resident macrophages involved in the phagocytosis of pathogens, clearance of debris, and secretion of growth factors for tissue repair. In addition, M-CSF is involved in regulating bone homeostasis by stimulating osteoclast differentiation and activity. M-CSF is primarily produced by monocytes and macrophages themselves. It acts in an autocrine and paracrine manner to regulate the proliferation, differentiation, and survival of these cells. However, M-CSF is also produced in bone marrow stromal cells, fibroblasts and endothelial cells as a component in the local microenvironmental regulation of the immune cell function. M-CSF is often highly expressed in the tumor microenvironment where it recruits tumor-associated macrophages (TAMs) that suppress the native immune response leading to tumor progression and infiltration. M-CSF binds M-CSF R (CD115), a Receptor Tyrosine Kinase (RTK) family III member. |
| Tissue Specificity | Bone marrow stromal cells, spleen, vascular endothelial cells, endometrial secretory epithelium, respiratory and gastrointestinal epithelial cells, and synovial fibroblasts. |
| Cellular Localization | Membrane-bound and cleaved soluble protein forms |
| Involvement In Disease | Dysregulation of M-CSF is implicated in autoimmune disorders (rheumatoid arthritis, atherosclerosis, inflammatory bowel disease), osteoporosis, cancer tumor progression, cancer immune evasion, monocytic leukemia and neuroinflammatory processes in Alzheimer’s disease and multiple sclerosis. |
