Abstract: | Summary One bovine mammary epithelial cell clone, designated PS-BME-C1, and two bovine mammary epithelial cell lines, designated PS-BME-L6
and PS-BME-L7, were derived from mammary tissue of a pregnant (270 day) Holstein cow. The cells exhibit the distinctive morphologic
characteristics of mammary epithelial cells and express the milk fat globule membrane protein, PAS-III. They form domes when
cultured on plastic substrata and acinilike aggregates when cultured on a collagen matrix. These cells are capable of synthesizing
and secretingα-lactalbumin andα-s1-casein when cultured on a collagen matrix in the presence of insulin, cortisol, and prolactin. The cells have a near-normal
diploid number and do not grow in suspension culture. When transplanted to the cleared mammary fat pads of female athymic
nude mice, the cells readily proliferate forming noninvasive palpable spherical cellular masses within 8 wk after inoculation.
The cells may become a useful tool to study the regulation of ruminant mammary epithelial cell growth and differentation.
