How do cytokines and actomyosin contractility affect cell migration in vivo?

Abstract

The actin cytoskeleton regulates many cellular processes, primarily by providing the mechanical forces necessary for cellular shape change and therefore is essential for cell migration and invasion, both critical determinants during development and disease.

We propose to study cell migration in its 'native' environment, i.e. in a live animal, to improve the understanding of its underlying mechanisms. In particular, we will disturb actin contractility and the cytokine environment in a controlled manner. We will then investigate the effects using whole-body imaging to track the cells in vivo and metabolomics to determine cellular changes.
