Macrophage colony-stimulating factor (M-CSF) is a cytokine that regulates the survival, proliferation, differentiation, and functional activation of monocytes, such as macrophages and dendritic cells.

M-CSF has been used in vitro for the differentiation of human induced pluripotent stem cell (iPSC)-derived macrophages as well as the maintenance and development of monocytes in hematopoietic stem cell culture. M-CSF has also been used to influence macrophage polarization towards an anti-inflammatory or M2 macrophage phenotype.

Qkine M-CSF is a highly bioactive, animal origin-free (AOF), carrier protein-free 36.8 kDa recombinant protein with exceptional lot-to-lot consistency.
