Research topics and principle investigators of the RTG 2578

Distinct human and murine in vitro cellular differentiation models that represent different germ layers are used within the RTG 2578 in order to analyse the response of individual stem- and progenitor cells to model-relevant genotoxic agents. The implementation of various test systems and well-defined genotoxins together with an extensive analysis of relevant end points will foster multidisciplinary knowledge acquisition in genetic and developmental toxicology. As a result of the networked scientific research, synergistic effects are anticipated that favour knowledge in both basic research and translational concepts in distinct areas.
