Stem Cells and Organoid Biology
Title of project
Modulating Wnt signaling responses in stem cells and cancer
A 4-year PhD student position in the interdisciplinary area of regenerative medicine. The project will focus on the design, development and evaluation of peptide-based biologicals that modulate Wnt signaling responses in stem cells and cancer.
The lab of Madelon Maurice focuses on the mechanisms of signaling in stem cells, development and cancer. The lab is embedded in a dynamic and highly interactive research environment with international research groups and direct access to a large number of facilities. Local training opportunities include molecular cell biology, biochemistry, advanced imaging and genomics technologies.

Wnt proteins comprise a family of conserved, secreted glycolipoproteins that control the maintenance and proliferation of stem cell reservoirs during adult tissue renewal and regeneration after injury. Deregulated Wnt signaling due to mutations is strongly linked to cancer and degenerative disease. The responsiveness of stem cells to Wnt is tightly regulated by positive and negative feedback regulators that control Wnt receptor availability and activity. The ESR will embark on a project that aims to design innovative tools and methods to manipulate Wnt receptor activity in stem and cancer cells. The ESR will combine peptide-based reagents and protein engineering to modulate protein activity at the cell surface (collaboration Pepscan and Friedler). The ESR will map protein interaction sites of the developed reagents and employ advanced imaging and biochemical assays to determine consequences for receptor trafficking and turnover. The ESR will investigate how manipulation of Wnt receptor activity affects stem cell compartments as well as lineage decisions in complex tissues, using both healthy and patient-derived tumor organoids of different tissue origin. In summary, the ESR will be trained as a multidisciplinary scientist with know-how in protein engineering, biochemistry, imaging and applications in organoid technology.
