Sculpting the embryo as we wish!
Sculpting the embryo as we wish!
Our aim is to understand the cellular and molecular mechanisms underlying the morphogenetic processes that shape the embryo. How do cells behave collectively within the same population and communicate with different cell populations in three dimensions?
We use the gastrulating zebrafish embryo as a model system. With this system we can combine high resolution live-imaging analyses with sophisticated genetic manipulations to try and understand the following questions:
1. How do mesenchymal cells or epithelial cells keep themselves from behaving randomly?
2. How do normal cells detect transformed cells in a simple epithelium and eliminate them from the epithelium at the initiation of carcinogenesis?
3. How do epithelial cells co-ordinate their shape changes and propagate tension across the tissue?
