Mathematical modeling of spatio-temporal dynamics of Wnt signaling and its function in development and regeneration

Funding period: 2017-2025

Project B05

Project Leaders


The focus of this project is mathematical modeling of spatio-temporal dynamics of Wnt signaling leading to patterns of Wnt expression, and of their impact on symmetry breaking, tissue organization and maintenance. Mechanisms of pattern formation will be studied on the example of Hydra development and regeneration. The impact of Wnt signaling on stem cell activation and differentiation will be modelled in adult neurogenesis in mice. Mechanistic mathematical models will be built and validated iteratively, based on data provided by collaborating projects.
