Abstract: Colony-stimulating factor 1 receptor (CSF1R, Fms) is an integral transmembrane glycoprotein with tyrosine specific protein kinase activity that it is found on the mononuclear phagocytes to promote their survival, proliferation and differentiation. Colony-stimulating factor 1 (CSF-1), also known as M-CSF, is a protein ligand that acts on the CSF1R. There is a variable association of Fms with the stem cell marker CD34 on acute myeloid leukemia (AML) cells and this suggests different structures of the AML hierarchy in different patients. Mouse stromal cells (MS-5) were transduced with a plasmid containing human CSF-1 because mouse CSF-1 is inactive on human CSF1R. Results show that AML cells cultured with CSF-1-expressing stroma had a much better growth and survival than the control stroma, suggesting that CSF-1 might be a stimulating factor for the growth of leukemic stem cells.
