MECs structurally resemble both epithelial cells and smooth muscles. (a-c: hematoxylin and eosin staining, ×200) The tumor cells of the salivary duct, myoepithelial and EMC appeared to be a mixture with reciprocal transfer in the same area. In salivary glands and other exocrine glands, there are star-shaped cells lying between the basal lamina and the acinar and ductal cells. Myoepithelial cells (MECs) are considered to be a key participant in most salivary gland diseases, particularly tumors. Food is tasted and mixed with saliva that is secreted by several sets of glands. secretory carcinoma. Myoepithelial cells - Myoepithelial cells are located between the basal lamina and the secretory cells. Salivary glands. They are predominantly found in the parotid gland and represent approximately 1% of salivary gland tumours.
