3  -  Analysis of keratin dynamics during migration

We are interested in the role of keratin intermediate filaments during cell motility and the interdependence between keratin and the other cytoskeletal compounds, such as actin and microtubules. Keratin cycling in migrating cells and sessile cell will be quantified using image analysis tools. These values can be used for mathematical modeling of the transition from non-migratory to migratory. Chemical and genetic manipulations will be used in combination with novel imaging techniques to reconstruct the interactions between the cytoskeletal components. Together, this will lead to a better understanding in the cooperation between these components, needed for the highly regulated process of cell migration.
