| secretory cell | <biology> Cells specialised for secretion, usually epithelial. Those that secrete proteins characteristically have well developed rough endoplasmic reticulum, whereas conspicuous smooth endoplasmic reticulum is typical of cells that secrete lipid or lipid derived products (e.g. Steroids).

| Golgi epithelial cell | A glial cell found in the cerebellar cortex. See: Bergmann's fibres. (05 Mar 2000) |
| odontogenic epithelial cell | Epithelial layer that will give rise to teeth. (18 Nov 1997) |
| epithelial cell | One of the many varieties of cell's that form epithelium. (05 Mar 2000) |
| epithelial reticular cell | One of the many-branched epithelial cell's that collectively form the supporting stroma for lymphocytes in the thymus; believed to produce thymosin and other factors that control thymic function. (05 Mar 2000) |
| follicular epithelial cell | <physiology> A cell lining a follicle such as that of the thyroid gland. (05 Mar 2000) |
| androgen-dependent secretory protease | <enzyme> Glycoprotein from dog prostate; hydrolyzes arginine and lysine-containing amide and ester protease substrates Registry number: EC 3.4.99.- Synonym: ads-protease (26 Jun 1999) |
| secretory | <physiology> Secreting; performing, or connected with, the office secretion; secernent; as, secretory vessels, nerves. A secretory vessel; a secernent. Origin: Cf. F. Secretoire. See Secrete. Source: Websters Dictionary (01 Mar 1998) |

| secretory carcinoma | <tumour> Carcinoma of the breast with pale-staining cells showing prominent secretory activity, as seen in pregnancy and lactation, but found mostly in children. Synonym: juvenile carcinoma. (05 Mar 2000) |
| secretory component | <physiology> A glycoprotein found in a variety of external secretions (tears, bile, colostrum) usually complexed to secreted polymeric immunoglobulins (IgA or, less frequently IgM). It is derived, by proteolytic cleavage, from the polymeric immunoglobulin receptor (receptors, polymeric immunoglobulin) and probably functions to protect the immunoglobulins from proteolysis in the secretions. (12 Dec 1998) |
| secretory component of IgA | <immunology, protein> A polypeptide chain of about 60 kD that aids secretion of the IgA, a portion of the IgA receptor on the plasmalemma of the inner side of the epithelial cells lining the gut, which is proteolysed when the IgA receptor complex has travelled through the cell after receptor mediated endocytosis at the inner face, to the outer (luminal) face. (18 Nov 1997) |
| secretory cyst | A cyst resulting from some obstruction to the excretory duct of a gland. Synonym: distention cyst, secretory cyst. (05 Mar 2000) |
| secretory duct | A type of intralobular duct found in some salivary glands that modifies the secretory product; it derives its name from extensive infolding of the basal membrane. Synonym: salivary duct, secretory duct. (05 Mar 2000) |
