TPI.tv: improving science through animal-free innovations and research
Introducing TPI.tv : a video platform by experts striving to improve science through animal-free innovations and research.
A New Way to Evaluate Chemical Safety and Assess Risk
Monique Janssens (personal account): Why we need the Transition towards Animal-free Innovations
Why is there a Transition towards Animal-free Innovations, while we have the 3Rs, including Replacement? Well, there is a difference. Animal experiments should no longer be the golden standard of reference. We should not ask: Is this animal-free method good enough to replace animal experiments? But: What is the research question, and how do I get the best answer, preferably without animals? I know that many researchers are doing this already. But we can do even more! It’s also about involving the full chain of parties, including patients, financers, legislators and companies. That is why the transition movement works with interdisciplinary networks and Helpathons. The transition helps to innovate, to accelerate and to implement. At the same time, there is no need to throw the 3Rs overboard. Actually, we owe applying them to the lab animals of today. But by innovating we can develop even more new practices in research and education that bring about better results for science in less time and often with less costs. Without using animals.
FirstbaseBIO - human brain organoids for studying neurological diseases
Human neurological diseases are still poorly understood, amongst others because animals are used as a model for the human brain. A way to overcome this problem is to mimic human brain functioning in a dish with organoids. FirstbaseBIO is developing off-the-shelf brain organoids on which neurological diseases can be studied. This 3D platform will be formed by reprogrammed human cells from easily accessible sources, for example urine, skin, or mucosa. The proof of-concept brain organoids will be those from patients who are suffering from adrenoleukodystrophy (ALD), a rare, incurable brain disease that occurs primarily in young boys and is often fatal. With the brain organoid platform, possible medicinal treatments for ALD can be effectively optimised. FirstbaseBIO was nominated for the Venture Challenge 2021 for their development of human brain organoids to study neurological diseases.
GUTS BV - small intestine-on-a-chip and advanced computational analysis for compound and protein screening
GUTS BV is a contract research organization offering its 3-dimensional state-of-the-art small intestinal in vitro model in combination with custom computational analysis approaches. The small intestinal model was developed during Dr. Paul Jochems PhD research at Utrecht University in the group of Prof. Roos Masereeuw. In comparison to the current gold standard (Transwell model), they show improvement in cell differentiation (all major specialized cell types present), physiological structure (3D tube- and villi-like structures) and a functional epithelial barrier. After acquiring experimental data from this model computational analysis approaches are used to score and compare measured compounds for all tested biological parameters at once. The combined effort of improved in vitro modelling and data analysis is believed to result in an enhanced preclinical predictability. GUTS BV was nominated for the Venture Challenge 2021 for their development of an intestinal model combined with advanced computational analysis for protein and chemical compound screening.

Avatar Zoo - teaching animal anatomy using virtual reality
Animals are essential to train the next generation of scientists understand diseases and develop treatments for humans as well as animals. Therefore, animals are used for educational purposes. Technologies such as Virtual Reality and Augmented Reality can be employed to reduce the number of animals in the future. Prof. Dr. Daniela Salvatori is working on the development of 'Avatar Zoo' together with UMCU and IT. Live animals are replaced by holographic 3D in this flexible platform. With these holograms one is able to study the anatomical, physiological and pathological systems and processes of all kinds of animals. Avatar Zoo won the Venture Challenge 2021 for the development of virtual reality models that can be used for anatomy classes and practical training.
