Dr. Polyak and colleagues explored the involvement of the microenvironment in tumor progression by examining myoepithelial cells, which are known to play a critical role in mammary gland ...

Most breast tumors begin in the cells that line the interior of breast milk ducts. These cells in turn are surrounded by myoepithelial cells, Ewald says, which work together to contract and move milk ...

These cavities fill with milk-creating cells called cuboidal cells, which are surrounded by the myoepithelial cells. When the alveoli combine they are called lobules. In the anatomy of the nipple ...
