Differentiation of human chondrocytes under the influence of microalgae-based exopolysaccharides

  • BACKGROUND: Exopolysaccharides are formed by microalgae in response to adverse conditions and are found mainly as a coating around the cells. The protective function of EPS plays an important role in the survival of microalgae in polluted habitats. So far, the particular biological and physico-chemical properties of EPS have not been adequately investigated and their effect on cells such as human chondrocytes has not been tested. Microalgae in particular offer an ideal platform for the production of dietary supplements or drugs that enable new therapeutic approaches. METHODS: To investigate the influence of EPS on human chondrocytes, cytotoxicity and differentiation potential were analyzed in 3D cultures. RESULTS: We were able to demonstrate a positive, but donor-specific influence of EPS on the differentiation of human chondrocytes. Furthermore, the EPS showed no cytotoxic effects in a range of up to 250 µg EPS per ml medium. CONCLUSION: EPS have the potential to positively influence the differentiation of humanBACKGROUND: Exopolysaccharides are formed by microalgae in response to adverse conditions and are found mainly as a coating around the cells.

Further experiments are necessary to analyze the donor-specific effect.show moreshow less
