Abstract

Abstract Medicinal compositions containing a polypeptide growth factor having mitogenic activity are stabilized against loss of biological activity in the presence of moisture by including in said compositions a stabilizing amount of a water-soluble polysaccharide, preferably a cellulose derivative, such as methylcellulose or a hydroxy alkylcellulose, such as hydroxypropyl methylcellulose.
