History

Two research teams independently identified mouse colony stimulating factors in the 1960s: Ray Bradley at University of Melbourne and Donald Metcalf at Walter and Eliza Hall Institute, from Australia, and Yasuo Ichikawa, Dov Pluznik and Leo Sachs at the Weizmann Institute of Science, Israel. In 1980 Antony Burgess and Donald Metcalf discovered that mouse lung conditioned medium contained at least two different CSFs - GM-CSF, which they had purified in 1977 and a G-CSF which stimulated the production of colonies of neutrophils.
