chalone
Originally, a hormone ( e.g., enterogastrone) that inhibits rather than stimulates; now, any one of a number of mitotic inhibitors (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. + chalao, to relax, + -one]
