Organ-on-chip (OoC) systems are small microfluidic platforms that mimic the physiologically perfused microenvironment of cells in their tissue unit. Three-dimensional chambers and micron-scale channels integrated into the chips, as well as special geometric, mechanical and biological properties and components, physiologically simulate complex human biological processes outside the human body. These in vitro test systems can be used to answer a wide range of medical, biological, pharmacological and toxicological questions without having to use laboratory animals. With our international team, we work interdisciplinary at the interface between material and engineering sciences, physics, biology and medicine.
In close cooperation with the 3R-Center Tübingen for in vitro models and animal testing alternatives, we offer the possibility through our research to reduce the use and necessity of animal testing according to the 3R principle (Replace, Reduce, Refine), to increase the transferability of preclinical results to the clinical phases and thus to make the entire development more cost-effective, safer and faster.
