Human urinary macrophage colony-stimulating factor (hM-CSF) is a glycoprotein with a molecular weight of 85 kDa which consists of two homologous subunits with a molecular weight of 43 kDa. It stimulates monocyte production through the stimulation of progenitor cells to differentiate to mature monocytes as well as neutrophil production through the stimulation of mature monocytes to produce granulocyte-macrophage and granulocyte CSF. It also enhances platelet production through the production of megakaryocyte potentiator (Meg-POT). Recently, proteoglycan type M-CSF has been found by our group. This type of M-CSF has a molecular weight of greater than 200 kDa and consists of a 43 kDa subunit and a 150-200 kDa subunit, the latter of which contains chondroitin sulfate glycosaminoglycan. This proteoglycan type M-CSF binds to extra-cellular matrix at the part of glycosaminoglycan. In addition to hematopoiesis-stimulating activity, M-CSF has a promoting activity on monocyte tumor-killing, osteoclast production and differentiation of cytotrophoblasts to syncytiotrophoblasts which secrete gonadotropin. M-CSF receptor (M-CSF-R) was found as a product of proto-oncogene, c-fms which consists of 972 amino acids. Mutations at Tyr 969 and Ser 301 of M-CSF-R has been found in patients with myelodysplastic syndrome and monocytic leukemia.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D015398	Signal Transduction	The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

D016173	Macrophage Colony-Stimulating Factor	A mononuclear phagocyte colony-stimulating factor (M-CSF) synthesized by mesenchymal cells. The compound stimulates the survival, proliferation, and differentiation of hematopoietic cells of the monocyte-macrophage series. M-CSF is a disulfide-bonded glycoprotein dimer with a MW of 70 kDa. It binds to a specific high affinity receptor (RECEPTOR, MACROPHAGE COLONY-STIMULATING FACTOR).

D016298	Hematopoietic Cell Growth Factors	These growth factors comprise a family of hematopoietic regulators with biological specificities defined by their ability to support proliferation and differentiation of blood cells of different lineages. ERYTHROPOIETIN and the COLONY-STIMULATING FACTORS belong to this family. Some of these factors have been studied and used in the treatment of chemotherapy-induced neutropenia, myelodysplastic syndromes, and bone marrow failure syndromes.
