Popis: |
The influence of nicotine on cell differentiation was investigated. Cultures of human keratinocytes (HaCaT) were stained with an antibody against pan- keratin. They showed a more ordered keratin pattern with a nicotine concentration starting at 0.1 μg/ml in contrast to the control cultures. The expression of the keratins 1 and 10/11, which are regarded as differentiation markers [13, 15], increased after treatment with low nicotine concentrations (0.1–10 mg/ml medium). The number of “cornified envelopes” increased at a concentration of 0.1–100 μg nicotine/ml medium. In two-dimensional SDS-gel electrophoresis, cytokeratin 1 appeared at a nicotine concentration of 1 μg/ml medium. This was not found in parallel controls. This demonstrates that low concentrations of nicotine have a supporting influence on the keratinization and cornification of HaCaT keratinocytes. |
