Commercial supplier for CSF-1?

[Brian T. Greuel]

Does anyone know of a commercial supplier for colony stimulating factor-1 
(CSF-1; i.e. the ligand for the receptor encoded by the fms oncogene)?  Is it 
going by another name these days?

What is the difference between CSF-1 and the following factors:  G-CSF, GM-
CSF, and M-CSF?

Thanks for any information you can provide.
