Helpathon #4 - can you help Raissa?
Can you help Raissa find a more complex organoid-like brain and immune model based on rhesus microglia to study aging in relation to neuroinflammation and neurodegenerative diseases?

Raissa Timmerman is a PhD student at the alternative unit at the Biomedical Primate Research Center. A better understanding of aging of the brain is key to studying neuroinflammation and neurodegenerative diseases. We believe there is a potential for breakthrough in using our existing live macaque data obtained from past aging experiments to develop more complex in vitro rhesus brain-like models and then to correlate all this data with data from human in vitro models and human live data.

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.

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.
