| keratinised | Having become horny. Synonym: cornified. (05 Mar 2000) |
|---|---|
| keratinised cell | The dead keratin-filled squamous cell of the stratum corneum. Synonym: horny cell, keratinised cell. Origin: cornea, L. Fem. Of corneus, horny, + G. Kytos, cell (05 Mar 2000) |
| keratinising epithelium | <cell biology> An epithelium such as vertebrate epidermis in which a keratin rich layer is formed from intracellular cytokeratins as the outermost cells die. (18 Nov 1997) |
| keratinization | Keratin formation or development of a horny layer; may also apply to premature formation of keratin. Synonym: cornification, hornification. (05 Mar 2000) |
| keratinocyte | <pathology> Skin cell, of the keratinised layer of epidermis: its characteristic intermediate filament protein is cytokeratin. (18 Nov 1997) |
| keratinocyte growth factor | <growth factor> A growth factor structurally related to fibroblast growth factor. (18 Nov 1997) |
| keratinocytes | Epidermal cells which synthesise keratin and undergo characteristic changes as they move upward from the basal layers of the epidermis to the cornified (horny) layer of the skin. Successive stages of differentiation of the keratinocytes forming the epidermal layers are basal cell, spinous or prickle cell, and the granular cell. (12 Dec 1998) |
| keratinophilic | Denoting fungi that use keratin as a substrata, e.g., dermatophytes. Origin: keratin + Gr. Philos, love, attraction, + -ic (05 Mar 2000) |
| keratinosome | A membrane-bound granule, 100 to 500 nm in diameter, located in the upper layers of the stratum spinosum of certain stratified squamous epithelia. Synonym: lamellar granule, membrane-coating granule, Odland body. (05 Mar 2000) |
| keratinous | 1. Relating to keratin. Synonym: horny. (05 Mar 2000) |
| keratinous cyst | An epithelial cyst containing keratin. (05 Mar 2000) |
| keratins | Group of highly insoluble fibrous proteins (of high _ helical content) which are found as constituents of the outer layer of vertebrate skin and of skin related structures such as hair, wool, hoof and horn, claws, beaks and feathers. Extracellular keratins are derived from cytokeratins, a large and diverse group of intermediate filament proteins. (18 Nov 1997) |
| keratitis | <ophthalmology> Inflammation of the cornea. Compare: keratoconjunctivitis. (18 Nov 1997) |
| keratitis disciformis | Large disk-shaped infiltration of the central or paracentral corneal stroma. This lesion is deep and nonsuppurative and is seen in virus infections, particularly herpetic. Synonym: keratitis disciformis. (05 Mar 2000) |
| keratitis filamentosa | A condition characterised by the formation of epithelial filaments of varying size and length on the corneal surface. Synonym: keratitis filamentosa. (05 Mar 2000) |
