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 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.
