Myoepithelial Cells (MEC) of the Salivary Glands in Health and Tumours.

Myoepithelial cells (MEC) are found in the secretory units of many mammalian exocrine glands such as mammary, sweat, lacrimal and salivary glands. They are interposed between the secretory cells and the basal lamina. Immunohistochemically they are found to contain keratin intermediate filaments and are, therefore, considered to have an epithelial origin but at the same time they contain a large number of myofilaments which represent a massive expression of contractile proteins such as actin, myosin, calponin and caldesmon.

The role of myofibroblasts in wound healing, contraction and its clinical implications in cleft palate repair.

Myofibroblasts after its discovery in 1971 as the principal cell for wound healing has come a long way as far as research is concerned.
