Under either of the two circumstances, mammary epithelial cells would grow out of control and eventually result in cancer.

It has also been found that CK plays a critical role in the proliferation of human mammary epithelial cells.

Fatty acid-binding protein 3 gene contains four exons and its function is to arrest growth of mammary epithelial cells.

He took a mammary cell from an adult sheep and prepared its DNA so it would be accepted by an egg from another sheep.

Dolly is derived from a single mammary cell.

Conventional wisdom would have dictated that mammary cells, which are highly differentiated and specialized, could produce only more mammary cells.

Even in a fetus, a fibroblast is as highly specialized and fully differentiated as a mammary cell.

In a study, 8-prenylnaringenin has activated proliferation of mammary cells.

The Posilac then sustains already-present mammary cells, limiting the rate of production decrease after production peaks.

(It was a geek's joke: Dolly was cloned from a mammary cell.)
