Major Research Interests
Regeneration, the ability of many animal or plant species to re-grow lost body parts, raises many intriguing questions. For example, what defines the shape, size, and proportions of the regenerating body part? After an injury, how can the remaining tissue ‘sense’ what’s missing? Why is that regeneration seemingly the exception rather than the rule? Or why
We use planarian flatworms as model system. Thanks to their abundant pluripotent adult stem cells, many planarian species have the fascinating ability to regenerate complete animals from tiny tissue pieces. Moreover, they continuously renew all cell types even in absence of injury and the resulting dynamic tissue architecture manifests for example in the food-supply dependent bi-directional scaling of body size over a > 40-fold range in body length, a >800-fold range in cell numbers or close to a 10,000 fold range in weight1. And some species continuously grow and shrink, while others age and die.
Our department uses a highly interdisciplinary compendium of methods to study these fascinating phenomena. We probe the self-organizing signaling systems that specify the planarian body plan in terms of biochemistry and cell biology2,3. We sequence genomes4 and develop functional genomics approaches in order to understand how patterning signals program stem cell progeny fate choices or how signaling networks form spatial activity patterns. We explore the quantitative basis of pattern formation, scaling, and size specification in close collaborations with physicists and theoreticians1,2,5. And through worldwide field sampling, we maintain a “zoo” of > 50 planarian species to mechanistically compare regenerative abilities6, body sizes and shapes, organismal life spans, or reproductive strategies between species.
In a nutshell: We study fundamental molecular/cell biological mechanisms and how and why they change in evolution.
