Zebrafish in toxicity testing

Zebrafish are increasingly recognised as a useful model for toxicity testing of chemical substances. Testing strategies are becoming more based on mechanisms of toxicity structured in adverse outcome pathways describing the chain of events leading to toxicity or disease. Using a battery of dedicated in vitro and in silico assays, insight can be gained in how exposure leads to disease. For certain diseases it is known that toxicity relies on the interaction between different organs and cell types, which requires research on whole organisms in addition to simple in vitro models. The zebrafish is considered a valuable whole organism model in a mechanism-based testing strategy. At RIVM, the zebrafish embryo model is used for testing the effect of chemical substances on several adverse outcomes and diseases.

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.

From 2D hiPSC culture to developing a 3D vessel-on-chip

Theano Tsikari is a 2nd year PhD student at the Orlova group at LUMC. As part of the LymphChip consortium, her project focuses on the development of immunocompetent organ-on-chip models of the cardiovascular system, and especially the integration of tissue-resident macrophages and lymphatic vasculature using human induced pluripotent stem cells. In this video, you can follow her as she presents you the backbone of her project, a 3D hiPSC-derived vessel-on-chip model, that has been previously developed in the Orlova group and can be employed for the generation of advanced in vitro models of vascular diseases.

Charlotte Blattner, Harvard Law School: Transition needs community efforts

Charlotte Blattner is a visiting researcher at Harvard Law School on the Animal Law & Policy Program and explains that a transition is needed to move away from animal testing. This transition needs to be a just transition, a community effort where all stakeholders are involved to replace animal testing for animal-free innovations.

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.

User Research in developing the virtual human platform

Digital tools can support the phasing out of animal-based tests and data in chemical risk assessment. This is one of the core promises of the Virtual Human Platform. The potential contribution of digitalization is linked to the acceptance and adoption of tools, methods, and data by stakeholders in several societal sectors. To facilitate the integration of stakeholders in the configuration of digital tools, Dr. Isaac Ortega Alvarado and colleagues gather insights from risk assessors in their role as users. Risk assessors are the ones who actualize chemical risk assessment and its standards through their practices. With this perspective, this research contributes to understanding the development and implementation of digital tools as embedded in social processes of construction and reception.
