The goal of our research activities is to culture human cells under physiological conditions. To do so, we employ different three-dimensional (3D) cell culture systems. Depending on the application the cells are cultured in scaffold-free or in scaffold-based systems. We have expertise in bioprinting for many years and use the promising technology successfully in industry-driven projects. Bioprinting allows producing living tissues in a layer-by-layer mode by depositing cells, (extracellular) matrix and bioactive molecules precisely in 3D space. The 3D tissues are developed for drug and substance testing, as well as for personalized medicine
