Specifications

Macrophage colony stimulating factor (M-CSF) is produced by many cell types, including fibroblasts, endothelial cells, monocytes and granulocytes. M-CSF was initially identified on the basis of its ability to stimulate the growth of macrophage/granulocyte containing colonies in soft agar cultures. M-CSF stimulates the development of hemopoietic stem cells into macrophages and supports the growth and differentiation of monocytes.
