Help needed : EGF cytokine ?

[Jochen Hardt]

Hi there !

A friend of mine is finishing her thesis in biology. To help her, I 
offered to post a question to this group.
Can anybody name a reference paper in which the Epidermal Growth 
Factor (EGF) is mentioned as cytokine ?

Any hints are gratefully appreciated !
