To develop comprehensive cell migration models, InCeM will focus on the main structural (actin, keratin, adhesions) and regulatory (GTPases and kinases) factors in force generation. Technically challenging simultaneous monitoring of multiple factors will be conducted at cellular and subcellular resolution for subsequent mechanistic and predictive mathematical modelling.

Migrating primary keratinocyte with labelled cell adhesions. Based on a fine tuned regulation adhesion structures are continuously formed, modified and finally disassembled.
Primary keratinocytes apply traction forces upon migration. Using fluorescent fusion proteins (GFP-vinculin), adhesion structures can be visualized. Those sites are used by the cell for cell force transmission to the underlying substrate. In case those substrates are elastic, forces cause deformation fields that can be visualized using marker particles.
