Project description:

Three-dimensional cell culture models offer the possibility to mimic physiological conditions in vitro better than classic two-dimensional approaches. One technology to produce such three-dimensional cultures is 3D-bioprinting, which means that living cells are printed in a three-dimensional manner. 3D bioprinting has great potential to produce humanized organ models composed of multiple cell types with high spatial resolution.This project is part of the EC3R research concortium and provides the 3D-bioprinting technology to the consortium members. The project will developdan advanced liver model composed of multiple cell types that are positioned in a biologically relevant arrangement. In addition to parenchymal hepatic cells, different non-parenchymal cells, including endothelial cells, stellate cells and macrophages will be included that are considered essential for the biological function of the liver. To date, numerous variants of liver models have been described in the literature, some of which are highly sophisticated and complex; however, they usually rely on the use of commercially unavailable printers developed in-house and/or limited patient-derived material, so that they are not readily available to the scientific (academic) community. The project will address these limitations by employing only commercially available bioprinting devices and cell sources that are available in sufficient amounts. We will provide bioprinted liver models for the collaborators in their 3R-related projects. In this project, we will analyze hepatotoxicity of pyrrolizidine alkaloids and various pesticidal active compounds.
