Sentences with word «myoepithelial»
Myoepithelial refers to a type of cell that is found in many tissues of the body. These cells have the ability to contract, similar to muscle cells, and are usually located near glandular or secretory cells. They help to regulate the flow of fluids and assist in the function of the glands they are associated with. Full definition
Smooth muscle cells called myoepithelial cells surround the alveolar glands and milk ducts.

Ducts are lined with myoepithelial cells.
The tissue, called the stroma, includes fat cells, or adipocytes, that provide padding; fibroblasts, which make the framework for tissue; pericytes in blood vessels, which are contractile cells that help regulate blood pressure; as well as myoepithelial cells comprising the outer layer of the ductal system through which milk flows.
Further tests suggested that epithelial cell progenitors helped by restoring the connection between cells called myoepithelial contractile cells and the lacrimal gland's secretory cells, which produce tears.
The basic components of the mammary gland are the alveoli (hollow cavities, a few millimetres large) lined with milk - secreting cuboidal cells and surrounded by myoepithelial cells.
The researchers have shown that this marker protein changes myoepithelial cells in breast tissue to promote tumor cell invasion in vitro and enhances mammary tumor growth in vivo.

Rare spontaneous myoepitheliomas arising from myoepithelial cells of various exocrine glands have been observed in The Jackson Laboratory substrains.
The myoepithelial cells can contract, similar to muscle cells, and thereby push the milk from the alveoli through the lactiferous ducts toward the nipple, where it collects in widenings (sinuses) of the ducts.
This interaction causes the myoepithelial cells — on the outer layer of the ductal structure — to contract, squeezing the luminal cells within.
