However, both scarcity of tissue supply and donor variability of primary cells create a need for the development of alternative hepatocyte systems. By using a lentivirus vector system to transfer coding sequences of Upcyte® proliferation genes, we generated non-transformed stable hepatocyte cultures from human liver tissue samples. Here, we show data on newly generated proliferation-competent HepaFH3 cells investigated as conventional two-dimensional monolayer and as organotypical three-dimensional (3D) spheroid culture. In monolayer culture, HepaFH3 cells show typical cobblestone-like hepatocyte morphology and anchorage-dependent growth for at least 20 passages. Immunofluorescence staining revealed that characteristic hepatocyte marker proteins cytokeratin 8, human serum albumin, and cytochrome P450 (CYP) 3A4 were expressed. Quantitative real-time PCR analyses showed that expression levels of analyzed phase I CYP enzymes were at similar levels compared to those of cultured primary human hepatocytes and considerably higher than in the liver carcinoma cell line HepG2. Additionally, transcripts for phase II liver enzymes and transporter proteins OATP-C, MRP2, Oct1, and BSEP were present in HepaFH3. The cells produced urea and converted model compounds such as testosterone, diclofenac, and 7-OH-coumarin into phases I and II metabolites. Interestingly, phases I and II enzymes were expressed at about the same levels in convenient monolayer cultures and complex 3D spheroids. In conclusion, HepaFH3 cells and related primary-like hepatocyte lines seem to be promising tools for in vitro research of liver functions and as test system in drug development and toxicology analysis.

Jahrestagung der Deutschen Gesellschaft für Klinische Mikrozirkulation und Hämorheologie : Programm, 22. und 23. November 2019, Braunschweig N2 - 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 human chondrocytes. Further experiments are necessary to analyze the donor-specific effect.
