myoepithelial การใช้

• As the name suggests, it consists of myoepithelial cells.
• Secretion of sweat occurs when the myoepithelial cell cells surrounding the secretory glands contract.
• Oxytocin stimulates contraction of the myoepithelial cells surrounding the alveoli, which already hold milk.
• The inner layer of the epidermis contains a nerve net, and myoepithelial cells that act as muscles.
• The intralobular ducts are usually lined with simple cuboidal epithelial cells that are lined by myoepithelial cells as well.
• In addition to nonspecific duct widening the myoepithelial cell layer is atrophic, missing or replaced by fibrous tissue.
• The mouth is at the anterior end, and opens into an elongated muscular pharynx with a triangular or Y-shaped myoepithelial cells.
• The myoepithelial cells contract under the stimulation of oxytocin, excreting the milk secreted by alveolar units into the lobule lumen toward the nipple.
• If the lesion is NS, there will be focal to absent immunoreactivity for p53, low immunoreactivity for p63-and calponin-positive myoepithelial cells.
• Decreased expression of laminin-111 and the growth-inhibitory signals that it produces in malignant myoepithelial cells begs for further investigation with regard to cancer research.
• It is also known as " Mixed tumor, salivary gland type ", which describes its pleomorphic appearance as opposed to its dual origin from epithelial and myoepithelial elements.
• The histologic appearance of these tumors varied, but all shared the common feature of a biphasic proliferation of metastasize and therefore should be designated as epithelial-myoepithelial carcinoma.
• Carbetocin has also been shown to stimulate milk letdown through its action on the oxytocin receptors on the myoepithelial cells and there was not a significant amount of carbetocin in breastmilk.
• The histologic differential diagnosis includes mucoepidermoid carcinoma ( clear cell variant ), acinic cell carcinoma ( clear cell variant ), epithelial-myoepithelial carcinoma and metastatic clear cell carcinoma.
• "' Pleomorphic adenoma "'is a common benign salivary gland neoplasm characterised by neoplastic proliferation of parenchymatous glandular cells along with myoepithelial components, having a malignant potentiality.
• Myoepithelial cells form a smooth muscle lining around the secretory cells; when the muscles contract, they squeeze the secretory ducts and push out the accumulated fluid into the hair follicle.
• "Breast " : Koebnerisin ( S100A15 ) is expressed by alveolar and small duct luminal cells and by epithelial-derived myoepithelial cells around acini and by surrounding blood vessels.
• The basic components of a mature mammary gland are the " alveoli " ( hollow cavities, a few millimeters large ) lined with milk-secreting cuboidal cells and surrounded by myoepithelial cells.
• ADAMTS4 is expressed in ovary, spinal cord, adrenal cortex, ciliary ganglion, trigeminal ganglion, brain, retina, pancreas ( islets ), fetal lung, breast myoepithelial cells, tendon and cartilage.
• An "'adenomyoepithelioma of the breast "', also "'adenomyoepithelioma "', is a rare tumour in the breast composed of glandular elements ( adeno-) and myoepithelial cells.
