PrecisionTox: transforming chemical safety assessment
In order to better protect human health and the environment from harmful chemicals, the European chemical agency (ECHA) pursues the objective of "zero tolerance" on non-compliance of chemical registration applications. In this video, scientists of the PrecisionTox project - an EU-funded project aiming to accelerate chemical safety assessment with 3Rs compliant models - explain how New Approach Methods (NAMs) provide rich biological data that can help close the data gap to increase acceptance of chemicals dossier while reducing, replacing and refining animal experimentation.

EURL ECVAM
The EU Reference Laboratory for alternatives to animal testing (EURL ECVAM) promotes and facilitates the use of non-animal methods in testing and research. It validates, disseminates and shares knowledge on the 3Rs (Replacement, Reduction and Refinement of animal experiments). In this video, Raffaella Corvi explains what EURL ECVAM does in the field of safety testing of chemicals while reducing laboratory animal testing.

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.
