Abstract

Epidermal growth factor is a polypeptide hormone that was previously identified only in mice. It causes proliferation and keratinization of epidermal tissues. An immune affinity column extraction technique was used to purify partially a substance from human urine which was similar to the mouse hormone in both its biological activity and immunoreactivity.
