chalone

Pronunciation: kā′lōn

Definition: Originally, a hormone (enterogastrone) that inhibits rather than stimulates; now, mitotic inhibitor (often glycoproteins) elaborated by a tissue and active only on that type of tissue, regardless of species; thus, a reversible tissue-specific mitotic inhibitor.

[G. + chalaō, to relax, + -one]
