The LG is composed of various kinds of cells such as acinar, duct, and myoepithelial cells. The acini express water channel proteins including aquaporin 5 (AQP5) for aqueous tear secretion [6].
The dedifferentiating mesothelium undergoes drastic simplification in its architecture, with both peritoneal and myoepithelial cells forming a simple epithelial layer of irregularly shaped cells (Fig.
Microscopically, it showed a biphasic pattern with an outer layer of clear myoepithelial cells and an inner layer of epithelial ductal cells arranged in mixed tubular to solid patterns (Figure 3, B).
Caption: Figure 1: Hematoxylin and eosin, 40x, myoepithelial cells arranged in a fascicular nested pattern separated by collagen stroma.
Encapsulated papillary carcinoma of the breast may or may not have positive myoepithelial cells, and this could explain the discrepant staining seen amongst authors for EMPSGC.
A) Control group: Some hair follicles and sebaceous glands in the dermis fibroblast cells with vimentin expression in some cells around the myoepithelial cell positive (Vimentin immun-staining, Bar 100 mm).
The principal cell type represent the epithelial cells and minor proportion of cells are ovoid to spindle shaped with hyperchromatic nuclei, representing myoepithelial cells. Another characteristic features is the numerous bare nuclei in the background.
Myoepithelial cells are specialized basal epithelial cells that are found in the secretory endpieces and intercalated ducts of the normal exocrine glands, such as the salivary glands, respiratory tract glands, lacrimal glands, mammary glands, prostate glands, and sweat glands.
Peripheral to the layer of secretory cells were elongated myoepithelial cells and their long axes were running parallel to the cyst wall.
PA is usually characterized by epithelial or myoepithelial cells, myxoid and/or osseous matrix.
CD10 Antibody (clone 56C6) preserves reactivity even in paraffin embedded material.5 In normal skin CD10 immunostainting is present in sebaceous glands, myoepithelial cells of eccrine and apocrine glands, periadnexal dermis, and inner root sheath cells of vellus hair follicles and occasional endothelial cells.6-8 CD10 has been recognized as a useful marker to differentiate BCC from trichoepithelioma (TE).9,10 It is not routinely used to differentiate BCC from SCC but it has been claimed in some articles that CD10 can be utilized as a specific marker to distinguish BCC from SCC.4,11-13
The coelomic epithelium of both the esophagus and the stomach has a typical structure and consists of two cell types--peritoneocytes and myoepithelial cells (Fig.
