Purified recombinant Human M-CSF protein Expression System: E.coli Bioactivity: The ED50 was determined by the dose-dependent stimulation of the proliferation of Mouse M-NSF-60 cells ? 1 ng/mL, corresponding to a specific activity of ? 1 x 10^6 units/mg.
M-CSF is a potent hematopoietic factor produced by a variety of cells including lymphocytes, monocytes, fibroblasts, endothelial cells, myoblasts and osteoblasts. It 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. The human is reactive in Mouse systems, but the Mouse molecule exhibits no activity on human cells. Alternative Names: CSF-1 protein, MGI-IM protein, Macrophage Colony Stimulating Factor protein
