The NAM Navigator: A unique repository for information on the validation and acceptance of New Approach Methodologies
The NAM navigator is an innovative knowledge portal to navigate you to and through valuable information on the development, standardization, validation and acceptance of New Approach Methodologies (NAM). The NAM Navigator acts as an online guide that provides specific information needed in each of these steps, thereby increasing the broad use of animal-free innovations.

VHP4Safety project
The safety testing of chemicals and pharmaceuticals traditionally relies on animal studies. However, these raise ethical concerns and often fail to accurately predict human responses. New scientific developments offer opportunities to build a Virtual Human Platform (VHP) for safety assessment, a platform that enables assessment based solely on human physiology and biology, integrating data from in vitro and in silico models. This video explains how we are developing the VHP through an interdisciplinary approach. Read the paper in the videolink or visit or VHP4Safety (https://vhp4safety.nl/) for more information.

AI agents for safer science: How AI is Changing Chemical Risk Assessment
This video introduces a novel approach to chemical safety, where intelligent digital agents guided by large language models support scientists in making faster, more transparent decisions. By automating complex workflows and integrating tools like the OECD QSAR Toolbox, these agentic systems help prioritise research, reduce reliance on animal testing, and pave the way for safer, more sustainable innovation.

NXTGEN Hightech Biomed
The Netherlands has strong academic knowledge in areas like Lab-on-Chip, Organ-on-Chip, artificial organs, and cell production technology. However, turning this knowledge into actual products is challenging due to the need for collaboration between different technological and biological specialists. The NXTGEN Hightech program (https://nxtgenhightech.nl/en/biomed/) addresses this by creating a collaborative environment where companies from various fields work together. This approach aims to transform academic insights into innovative products, benefiting both the industry and society.

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.

Ecotoxicology explained - interview by TOXstreams
Toxicology is a complicated area where you have to figure out if a chemical is safe for the entire human population? Well, some researchers in this field go even beyond, and instead of studying the safety of substances on “just” people, they focus on any living being on the whole planet. In this TOXstreams interview ecotoxicologists Dr Adam Lillicrap from the Norwegian Institute for Water Research and Dr Kristin Schirmer from the Eawag Science and Technology and co-founder of aQuaTox Solutions GmbH Solutions will explain what and how they do this.

PrecisionTox project – interview by TOXstreams
What do nematodes, zooplanktons, clawed frogs, fruit flies, zebrafishes and humans have in common? Well, they are all part of the EU-funded project PrecisionTox. In this teaser for the TOXstreams interview, PrecisionTox researchers explain how they are combining non-traditional test species with molecular and computational methods to better protect our society from toxic chemicals. Prof. John Colbourne, the project’s coordinator, Dr Gaëlle Hayot, Christina Cramer von Clausbruch will tell all you want to know. Click on the link in the video to watch the whole interview.

ONTOX project – interview by TOXstreams
Have you ever wondered how one can actually develop a new approach method (NAM) to replace animal testing in toxicology? The ONTOX project is creating not just one but six different NAMs. Indeed, this EU-funded project is focused on building NAMs to study repeated dose toxicity effects, an area of toxicology that still relies heavily on animal testing. Prof. Mathieu Vinken, the project’s coordinator, Jian Jiang, PhD, Anouk Verhoeven and Jonas van Ertvelde explain their work to TOXstreams. Click on the link in the video to watch the full episode.

Cultured human skin for burn research
Burns are often accompanied by a dysregulated immune response, which can lead to systemic inflammation, impaired immunity, and excessive scarring. A deeper understanding of the mechanisms behind burns—where wound healing and inflammatory reactions are severely disrupted—holds the key to improving patient outcomes. Patrick Mulder, a postdoctoral researcher at the Burn Research Lab in Beverwijk, the Netherlands, works with his colleagues to develop animal-free skin models based on human cells and patient-derived tissues. Using these innovative, human-relevant models, he aims to provide greater insight into the body’s response to burns and studies the effects of existing and new treatments on wound healing.

An iPSC-derived blood-brain barrier to model neurodegeneration
The blood-brain barrier is a layer of cells that protects our brain from harmful compounds. However, due to this tight barrier, many drugs to treat neurological diseases cannot enter the brain either.
There are currently no good models to test these types of drugs. Henrique Nogueira Pinto is a PhD candidate at the Vrije Universiteit in Amsterdam. He is developing a blood-brain barrier model coupled to mini-brains. With this model, he aims to more reliably test how drugs can be transported over the blood-brain barrier and what their effect on the brain is.
