An international team of researchers led by Prof. Marcel Leist (University of Konstanz) and Prof. Ellen Fritsche (Leibniz Institute for Environmental Medicine Research (IUF) Düsseldorf) has successfully tested their animal-free test battery on 120 substances. The results have shown that the test battery is not only technically implementable but above all possesses a measurement sensitivity that is on a level with animal experiments. Since only human cells are used the significance is higher than that of results from animal experiments.

The findings play an important role in the strategy of using human-relevant data for the assessment of developmental neurotoxicity. This is currently being developed by the European Food Safety Authority (EFSA).
