Mammary Epithelial Cells (MEC)

The breast is located between the shallow layer and deep layer of the superficial fascia of the skin.Mammary epithelial cells (MEC) is located in the alveolar space of the breast, which forms a complex network with the mammary gland and adipose tissue. A variety of growth factors and hormones in the growth, infiltration, prenatal and postnatal differentiation period, puberty and pregnancy stage will be significantly changed, the breast epithelial cells will respond to these changes.

Abnormal hormone levels and extracellular matrix component levels, and other genetic factors that have been shown to induce breast epithelial cell proliferation, may lead to breast cancer.In molecular biology, the protein domain Whey acidic protein (WAP) has been identified as a major whey protein in milk and is important in regulating the proliferation of mammary epithelial cells.Understanding the characteristics of mammary epithelial cells will help to determine the pathogenesis of breast cancer and propose new therapeutic options.
