Description

General description

M-CSF (macrophage colony-stimulating factor) is a potent hematopoietic factor produced by a variety of cells including lymphocytes, monocytes, fibroblasts, endothelial cells, myoblasts and osteoblasts. The protein works through its receptor CSF1R (colony stimulating factor 1 receptor). The human is reactive in murine systems, but the murine molecule exhibits no activity on human cells. Recombinant human M-CSF is a 36.8kDa homodimeric protein containing two 159 amino acid polypeptide subunits.

Application

M-CSF human has been used for the induction of osteoclastogenesis in human peripheral blood mononuclear cells.

Biochem/physiol Actions

M-CSF (macrophage colony-stimulating factor) is a key regulator of cellular proliferation, differentiation, and survival of blood monocytes, tissue macrophages and their progenitor cells. M-CSF has been shown to play important roles in modulating dermal thickness, and male and female fertility. M-CSF is clinically used in the treatment of infection, malignancies and atherosclerosis. It facilitates hematopoietic recovery after bone marrow transplantation. M-CSF also works as a pleiotropic growth factor and plays a crucial role in reproduction and organogenesis. Absence of it can result in reduced growth, neurological and reproductive problems, developmental defects in the mammary gland, bone and pancreas. M-CSF is also involved in the pathogenesis of cancer.

Physical form

Lyophilized from 10 mM Sodium Phosphate, pH 8.0 + 75 mM NaCl.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a stabilizer (example 5% Trehalose) and store in working aliquots at -20°C to -80°C.
