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.}, language = {en} } @misc{HerzogHansenMiethbaueretal., author = {Herzog, Natalie and Hansen, Max and Miethbauer, Sebastian and Schmidtke, Kai-Uwe and Anderer, Ursula and Lupp, Amelie and Sperling, Sebastian and Seehofer, Daniel and Damm, Georg and Scheibner, Katrin and K{\"u}pper, Jan-Heiner}, title = {Primary like human hepatocytes genetically engineered to obtain proliferation competence display liver biotransformation activity in 2D and 3D culture systems}, series = {Cell Biology International}, volume = {40}, journal = {Cell Biology International}, number = {3}, issn = {1095-8355}, pages = {341 -- 353}, language = {en} } @incollection{AndererSavkovic, author = {Anderer, Ursula and Savkovic, Vuc}, title = {Zelltherapien in der Regenerativen Medizin}, series = {Zellul{\"a}re Diagnostik und Therapie}, booktitle = {Zellul{\"a}re Diagnostik und Therapie}, editor = {Sack, Ulrich}, edition = {1.
