Thyroid Hormone & Brain Development: animal-free models for human safety assessment
The environment can have a significant impact on a child's health even before birth. Brain development begins in the first trimester and continues until the age of 25, with thyroid hormone playing a critical role. During early pregnancy, the fetus depends on the mother's thyroid hormone, and a disruption in the thyroid hormone balance can lead to cognitive and motor impairments in the child. As part of the VHP4Safety project, we are developing in vitro tests to measure the developmental neurotoxic effects caused by disturbances thyroid hormone concentrations. Current testing guidelines do not always include testing for neurodevelopmental effects, highlighting the need for new non-animal methods. At the Erasmus Medical Center, human cell lines representing brain cell types are cultured to study the effect of chemicals on the thyroid hormone balance. RIVM uses human stem cells to create neuron-astrocyte networks that mimic brain development. By combining these different assays and models, we are creating a comprehensive human-based testing strategy to assess developmental neurotoxicity. These advances are a critical step toward eliminating animal testing while protecting the health and environment of future generations.

RISKHUNT3R project – interview by TOXstreams
Many studies are focused on finding the next best tool or test to assess the risk associated with chemical exposure. That is all well and good, but even the perfect assay needs to be accepted by regulators before seeing the light of the day. And how do we do that? The guests in this webinar have some ideas on that as principal investigators of the EU project RISK HUNT3R. Prof. Bob van de Water, Dr Mirjam Luijten and Dr Andrew White explain what RISK HUNT3R is doing, what next generation risk assessment means and why it is so important.
