| epithelial cell | One of the many varieties of cell's that form epithelium. (05 Mar 2000) |
|---|---|
| epithelial cells | Cells that cover the surface of the body and line its cavities. (12 Dec 1998) |
| epithelial choroid layer | The layer of modified ependymal cells that forms the inner layer of the tela choroidea, facing the ventricle. Synonym: lamina epithelialis, epithelial choroid layer, lamina choroidea epithelialis, lamina choroidea. (05 Mar 2000) |
| epithelial cyst | A cyst lined with epithelium. (05 Mar 2000) |
| epithelial dysplasia | A disorder of differentiation of epithelial cells which may regress, remain stable, or progress to invasive carcinoma. (05 Mar 2000) |
| epithelial dystrophy | Corneal dystrophy affecting primarily the epithelium and its basement membrane. See: juvenile epithelial corneal dystrophy. (05 Mar 2000) |
| epithelial ectoderm | That part of the ectoderm separating from the neuroectoderm at about the fourth week of embryonic life; the epidermis and its specialised derivatives develop from it. Synonym: superficial ectoderm. (05 Mar 2000) |
| epithelial inlay | A skin graft wrapped (raw side out) around a bolus of dental compound and inserted into a prepared surgical pocket. Synonym: epithelial inlay, Esser graft. (05 Mar 2000) |
| epithelial lamina | The layer of modified ependymal cells that forms the inner layer of the tela choroidea, facing the ventricle. Synonym: lamina epithelialis, epithelial choroid layer, lamina choroidea epithelialis, lamina choroidea. (05 Mar 2000) |
| epithelial layers | See: epithelium. (05 Mar 2000) |
| Epithelial membrane antigen | <cell biology> Heavily glycosylated membrane glycoprotein. Encoded by the MUC 1 gene, has a molecular weight of around 300 kD, more than half of which is O linked glycan. There is a 69 residue cytoplasmic domain and the extracellular domain may extend hundreds of nanometres beyond the plasma membrane, the increased expression in carcinoma cells may reduce the adhesion and mask antigenic properties of the cells. Similar functions are ascribed to ASGP, epiglycanin and leucosialin. (18 Nov 1997) |
| epithelial migration | Apical shift of epithelial attachment, exposing more of the tooth crown. (05 Mar 2000) |
| epithelial myoepithelial carcinoma | <tumour> A salivary gland malignancy composed of an inner layer of ductal cells surrounded by a layer of clear myoepithelial cells. (05 Mar 2000) |
| epithelial nest | A focus of central keratinization within concentric layers of abnormal squamous cells; seen in squamous cell carcinoma. Synonym: epithelial nest, epithelial pearl, squamous pearl. (05 Mar 2000) |
| epithelial pearl | A focus of central keratinization within concentric layers of abnormal squamous cells; seen in squamous cell carcinoma. Synonym: epithelial nest, epithelial pearl, squamous pearl. (05 Mar 2000) |
