PhD position at the Applied Stem Cell Technologies group of the University of Twente
Are you fascinated by how it is possible for gut microbiota to interact with the brain? Are you keen to harness the potential of stem cell biology in combination with microfluidic chip fabrication to address this question? Read below for more information.
You will use human induced pluripotent stem cell-derived organoids of the brain, intestine and vagus nerve cultured onto a microfluidic chip to investigate key molecular aspects of human physiology and Parkinson’s disease. Under the supervision of a highly skilled post-doctoral scientist and in collaboration with other groups at the University of Twente you will use existing differentiation procedures to create brain stem, intestinal and vagus nerve organoids from pluripotent stem cells. Following their generation, you will culture them into home-manufactured microfluidic devices and validate the identity, stage of maturation, and functional activity of the organoids using biomarker (protein and mRNA) expression, imaging, epithelial barrier integrity and electrophysiological read-outs. Using CRISPR-Cas9-mediated gene editing you will modulate the genetic make-up of pluripotent stem cells to express potential features of interest to microbiome-gut-brain axis communication. You will generate bacterial cultures and use live cell stains to visualize their co-culture with intestinal organoids using advanced types of microscopy and study aberrations in their communication in response to Parkinson’s disease-related changes to normal physiology using classical biochemical read-outs such as ELISA, western blot and PCR.

About the department
Brain disorders present a global debilitating burden to society urgently calling for in-depth molecular understanding of their pathological processes to propel the development of effective therapeutic targeting strategies forward. While many brain-localized aspects are known that regulate brain function, interestingly, a feature located nearly a meter away from the brain critically drives brain activity and cognition. This feature comprises the intestinal microbiota, or microbiome, which is considered to interact with the brain via the intestinal microbiome-gut-brain axis. Perturbations in the richness and diversity of the microbiome are a common feature in many brain-related disorders, including neurodegenerative disorders such as Parkinson’s disease. Nevertheless, the molecules, cell types and signaling pathways involved in this multi-tissue process remain enigmatic. Studies into this topic remain sparse as a result of multi-organ complexity and challenges to accurately recapitulate this complexity by means of current systems to model the human physiological microbiome-gut-brain axis. This project aims to provide fundamental mechanistic insights into how long distance interaction aids the communication between the microbiome and brain health and disease by exploiting the differentiation potential of induced pluripotent stem cells into organoids. This project will use an integrated microbiome-gut-brain axis on a microfluidic chip from polycultured microbiome and stem cell-derived intestine, vagus nerve and brain connection to investigate key aspects of human physiology and Parkinson’s disease.
About the organisation
The Faculty of Science & Technology (Technische Natuurwetenschappen, TNW) engages some 700 staff members and 2000 students in education and research on the cutting edge of chemical technology, applied physics and biomedical technology. Our fields of application include sustainable energy, process technology and materials science, nanotechnology and technical medicine.
