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.

Using skin and mucosa models to replace animal testing
The skin and mucosa are important tissues that differ between species in health and disease. The group of Sue Gibbs works on the development of advanced in vitro models that mimic these two tissues, specialising in immunity models and organ-on-a-chip technologies. They use skin models to study for example melanoma, skin allergies, eczema, burns and healing wounds. Dental models are used for the safety of materials used in dentistry, for example to test the quality of the implant and false tooth when it comes to attaching to the soft tissue. Their ambition is to expand into the field of multi-organ technology to make even more relevant models for the human skin and mucosa.

Tumor-on-chips to study delivery of protein therapeutics
Valentina is a PhD candidate at the Department of Biochemistry at Radboudumc. Her research focuses on developing and applying organ-on-chip technologies, such as tumor-on-a-chip systems, to study the tissue-specific and cytosolic delivery of protein therapeutics. Valentina's research has also aimed at bridging the gap between engineers and biologists, promoting the use of microfluidic organ-on-chip technologies to answer more relevant biological questions. One example of this is the development of a mathematical model that could be applied to study drug delivery and diffusion in a tumor-on-a-chip system and to extrapolate possible outcomes of the delivery of therapeutic proteins to tumors in the human body. Another collaboration led to the development of a tumor-on-a-chip where hypoxic conditions can be replicated and investigated, and where the targeting of specific hypoxia markers in tumor cells can be investigated.

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.

SMART OoC platform: a standardized modular approach
The SMART Organ-on-Chip project aims to bring Organ-on-Chip technology to the next level, out of the pioneering labs to industrial applications. NWO awarded 4.8 million euro to a large and diverse consortium of universities, companies, research institutes and foundations, brought together by hDMT (Dutch Organ-on-Chip Consortium), that will together develop standardized Organ-on-Chip models. These models will be made to fit the scale and quality that pharmaceutical companies need to use them for development of novel drugs, with better science and less animal use as a result. The project will kick off in autumn 2021. More information on the project will follow in the course of 2021.

Human pluripotent stem cell derived cardiomyocytes for disease modelling and drug discovery
Berend van Meer did his PhD research in the research group of prof. Christine Mummery at the department of Anatomy and Embryology of the Leiden University Medical Center. In this group, human pluripotent stem cell derived (Organ-on-Chip) models are being developed, mostly cardiovascular models. The work of Berend aimed to understand how well these stem cell based cardiac models can predict the effect of (well-known) drug therapies in patients. Importantly, the outcomes of the experiments were compared to very similar measurements in rabbit heart muscle cells. And while animal models predicted less than 70% correctly, the human stem cell based models predicted almost 80% of the expected effects correctly. The research contributes to understanding the relevance of stem cell based models and strengthens the confidence regulators and pharmaceutical companies have in such models as animal alternatives in the drug development pipeline.
Berend van Meer has won the Hugo van Poelgeest prize 2020 for his research on human pluripotent stem cell derived cardiomyocytes for disease modelling and drug discovery.

Cartilage-on-a-chip for studying joint degenerative diseases
Carlo Alberto Paggi is currently a PhD candidate at the University of Twente in the research group of Prof. Marcel Karperien and Prof. Séverine Le Gac. Karperien’s lab focus on the biological aspects of osteoarthritic research while Le Gac’s specialize in organ-on-chip development. The project of Carlo Alberto is developing a joint-on-chip platform to create a reliable in vitro model to study disease progression in osteo- or rheumatoid arthritis. The model combines different organ-on-chips aimed at replicating each a tissue around the joint such as cartilage, bone and ligaments. This new technology focuses on better reproducing human models and at substituting the use of animal models for drug research.
