In the 1950’s and 60’s experimental analysis of the control by hormones of the growth and function of the mammary gland depended on two technical advances. First was the development of successful, minimally traumatic, surgical methods to remove t

The mammary gland is an example of a tissue of epidermal origin that depends for the development of its characteristic morphology on underlying mesenchymal cells. The interaction between mesenchyme and epithelium appears to be mediated by polypetide

Amphiregulin is a heparin-binding member of the epidermal growth factor (EGF) family, which we have recently shown to be expressed in sheep mammary gland. Uniquely among known EGF-like growth factors, its mitogenic activity is inhibited by soluble he

In non-equatorial regions most domesticated ungulates are seasonal shortday breeders; their breeding seasons are restricted to the au tumn and winter months, when day length, or photoperiod, is short. This is an adaptive feature, allowing the animals
