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.

Helpathon #11 – Can you help Terry?

Terry Vrijenhoek (UMC Utrecht) is a geneticist and explores the societal impact of gene therapy. In this Helpathon the focus is on Alzheimers, for which there is no cure but there is a promising RNA-based therapy in the pipeline. Can you help Terry with designing scenarios for responsible development for gene therapy for Alzheimer disease in terms of benefits, risks, budgets and animal models?

Helpathon #11 – Can you help Francesca?

Francesca Stillitano (UMC Utrecht) is a geneticist and an Assistant Professor at the Department of Cardiology. Francesca is currently working with mice models and with human tissue-based in vitro models to develop and test new gene therapies for a rare cardiomyopathy. Can you help Francesca with developing gene therapies for curing inherited cardiomyopathies without the use of animal models? More information can be found here (https://www.helpathonhotel.org/coming-up).

Stem cell derived Vessels-on-Chip to study brain disorders

Dennis Nahon is a PhD candidate in the Department of Anatomy and Embryology at the Leiden University Medical Center. In his research, under supervision of Dr. Valeria Orlova (https://www.orlovalab.com/) and Prof. Dr. Christine Mummery, he aims to mimic a blood vessel in the brain by combining different stem cell derived cell types, in a 3D Vessel-on-Chip model. Here, an example of these in vitro blood vessels is shown in which certain brain cells known as astrocytes (in white) interact with the blood vessels (in red). This model paves the way for investigating brain vessels outside the human body, while reducing the need for animal models.

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.

Unified organoid system for modeling heart and kidney interaction on-a-chip

Beatrice Gabbin is a PhD candidate at the Anatomy and Embryology Department of the Leiden University Medical Center. Her project is shared with the Nephrology Department and focusses on the study of the cardiorenal axis in vitro. Both heart and kidneys have vital functions in the human body and reciprocally influence each other’s behavior: pathological changes in one can damage the other. There are already multiple independent in vitro (human) models of heart and kidney, but none have so far captured their dynamic crosstalk. The aim of the project is therefore to develop a microfluidic system which can be used to study heart and kidney interaction in vitro. For this purpose, cardiac microtissues and kidney organoids derived from human induced pluripotent stem cells are generated and loaded onto a 3D perfusion chip for their dynamic co-culture. This system enables the study the cardiac and kidney interaction with a high level of control. The validation of a unified organoid system will enable the investigation of diseases involving the two organs and their potential treatments.

Modelling COVID-19-induced thrombosis using blood-perfused Vessels-on-Chips

A subset of hospitalized COVID-19 patients develops severe symptoms like microthrombosis and multiple organ-failure, worsening survival rates. The most inner layer of cells of a blood vessel, the endothelial cells, play a central role in the development of these complications. Their dysfunction can be replicated in advanced cell culture models like our blood-perfused Vessel-on-Chip to further understand disease mechanisms. In this short highlight, Huub Weener from the University of Twente shows how the technique works and what these models contribute to our knowledge of COVID-19.

This animation of the 3Rs Centre Utrecht shows the differences, but also the similarities, between the 3Rs (Replacement, Reduction, Refinement of animal testing) approach and the NAMs (New Approach Methodologies) approach when trying to replace or reduce experimental animal use.

Cells4Thought: using iPSCs for neurodevelopmental health

The prevalence of neurodevelopmental disorders (NDDs), including cognitive impairments, is increasing worldwide with great impact on daily life quality. There is evidence that exposure to chemicals may contribute to the incidence of NDD. However, a causal link is lacking. Towards this goal, a human-relevant in vitro model system mimicking parts of brain development, such as neuronal network functioning, could be used for mechanistic research on how gene-environment interactions contribute to the development of NDD. This is going to be studied in the project Cells4Thought, using induced pluripotent stem cells form different individuals to study the effect of chemicals on neuronal differentiation.

We all want a safer world for humanity, animals and the environment: Transition Animal-free Innovation

Why is the transition to animal-free research so important? What are animal-free models? How does TPI (Transition Animal-Free Innovation) encourage their development and use? And who are we working with to make this happen? We explain this in our animation. More and more animal-free tests and research methods are becoming available, but not all research questions or safety tests can be answered in this way yet. In addition, the validation, qualification and acceptance of non-animal innovations still lags behind. Therefore, the Dutch Ministry of Agriculture, Nature and Food Quality (LNV) stimulates the development and application of animal-free innovations. This is done with the partner programme Transition Animal-free Innovation (TPI).

ONTOX Hackathon: Hack To Save Lives And Avoid Animal Suffering

Artificial Intelligence (AI) in toxicology – a potential driver for reducing or replacing laboratory animals in the future. ONTOX project is looking for solutions and innovative ideas to move forward. Are you going to help ONTOX to hack into these complex challenges? The hackathon will be held from 21 to 23 April 2024 in Utrecht Science Park. The whole event is open to a diverse community of forward-thinkers and problem-solvers interested in the intersection of AI and ethical toxicology. The goal is to bring together passionate individuals who seek innovative solutions to critical challenges in toxicology.
