Katja Wolthers (Amsterdam UMC) - virus research in human models: let's show some guts!

To study viruses that make people sick, we often use laboratory animals. However, virus infections in animals are different than in humans. New 3D culture models or 'organoids', which look like human organs in a petri dish, offer a unique opportunity to investigate how viruses enter the human body and cause disease. Our research focuses on enteroviruses such as polio. Due to vaccination, polio is rare, but other enteroviruses are increasingly a threat to young children and patients with impaired immune defenses. There are no medications available, because knowledge about infections with enteroviruses is limited. In our research we use organoids to see how enteroviruses enter the human body and by which means you can prevent that, without the use of laboratory animals. With this project we want to show that our technique can replace the use of laboratory animals in virus research.

Whole blood assessment of thrombosis tendency

Transgenic animals are often subjected to short and long term experimental models of thrombosis and atherosclerosis with considerable discomfort to the animal. This project aims to: 1) replace (human blood instead of animal blood), 2) reduce (a few drops of blood per test), and 3) refine (replace in vivo by in vitro testing with isolated blood) the use of laboratory animals with two new small blood volume function tests—the perfusion chamber and the thrombin generation test. Both tests will be equipped with a simple detection capability, which is affordable for laboratories. Their application is not only in the field of thrombosis and haemostasis but also for the investigation of other blood-related diseases, such as arteriosclerosis, diabetes and cancer.

Nederlandse Brandwonden Stichting en Proefdiervrij proosten op samenwerking

De Nederlandse Brandwonden Stichting is het eerste fonds dat hardop uitspreekt geen proefdieren meer te gebruiken. Zij hebben expliciet in het beleid opgenomen om te investeren in innovatief proefdiervrij onderzoek als kwalitatief betere onderzoeksmethode. Dit sluit naadloos aan op onze eigen missie. Door onze krachten te bundelen, kunnen we samen veel bereiken.

Stem cell assays for animal-free developmental neurotoxicity assessment of compounds (video in Dutch)

Victoria de Leeuw worked as a PhD candidate in the research group of prof. Aldert Piersma at the RIVM between 2016 and 2020. Piersma's lab studies the effects of compounds on development of the embryo during pregnancy with among others stem cell cultures. The project of Victoria was aimed to differentiate embryonic stem cells (of mouse and human origin) into neurons and astrocytes, which could mimic small parts of embryonic brain development. These models were able to show some of the known toxic mechanisms induced by these compounds, congruent with what they we hypothesised to mimic. Therefore, these two stem cell assays make a useful contribution to the animal-free assessment of developmental neurotoxicity potential of compounds. Onderzoeker: Victoria de Leeuw op het RIVM.
