| pubmed-article:9456642 | pubmed:abstractText | The cells of the junctional epithelium (JE) provide and maintain the epithelial attachment, and remain morphologically and phenotypically distinct from oral sulcular (OSE) and external oral epithelia (EOE), from which they may be regenerated de novo. Expression of cytokeratins (CK) in human epithelia has been shown to be highly site-specific, implying a functional role. The aims of this study were to differentiate between the cytokeratin profiles of JE, OSE, EOE and pocket epithelia (PE) in health and disease, in smokers and non-smokers. | lld:pubmed |
