Oncostatin M (OSM) is a member of a cytokine family that includes a leukemia-inhibitory factor, granulocyte colony-stimulating factor, and interleukin 6. OSM is a growth regulator which inhibits the proliferation of some tumor cell lines. It can stimulate proliferation of AIDS-KS cells. It regulates cytokine production, including IL-6, G-CSF, and GM-CSF from endothelial cells. OSM is involved in the maturation of fetal hepatocytes, thereby promoting liver development and regeneration (PMID: 9133674; 29526757; 29363180; 21887386).

Recombinant Human OSM is used as part of our differentiation protocol, and is involved in the last stage in which we differentiate from a hepatoblast to a hepatocyte like cell. This product worked very well and aided with successful differentiation.
