Developmental neurotoxicity testing using stem cells
Children should grow up in a safe and healthy environment. Disruption of brain development may have enormous impact on future life and might result in disorders such as ADHD or cognitive decline. The effect of compound exposure on the developing brain is largely unknown, since in the current regulatory test procedures in experimental animals effects on the brain are rarely investigated and human relevance of these animal models is under debate.
Researchers at RIVM are developing a cell model based on human stem cells that mimics a small part of the developing brain. This method is human-relevant, animal-free, and based on mechanistic knowledge of human biology and physiology of brain development. The model can be an important component in a testing strategy to test the safety of chemicals and pharmaceuticals on the developing brain.
