| Popis: | "Human skin epithelium cells" (NCTC strain 2544; HSEpicell) are established cells and grow to a monolayer the same way as epithelial cells. Addition of proliferating or antiproliferating substances results in a typical dose-dependent influence on the cell growth: steroids inhibit mitosis, polyamines stimulate proliferation, while prostaglandin E2, theophylline and papaverine reduce cell growth. Since the pattern of chromosomal nonhistone proteins indicates alterations of gene activity, DNA-binding proteins of HSE picells are analysed. Compared to native human skin fibroblasts (La Col 1115) there are only slight differences, in contrast to cancer cells. Therefore HSE picells may represent undifferentiated non-cancer cells. Hydrocortisone and theophylline inhibit cell proliferation by different mechanisms. As indicated by the pattern of DNA-binding proteins, both substances also act on HSEpicells in two different ways. As HSEpicells can be used for studying cell regulation, water-soluble extract and DNA-binding proteins of psoriatic scales as well as sera of psoriasis patients are tested in respect to any proliferating component. However, no influence on cell proliferation could be found. |
