Mechanisms underlying cell migration

  • It moves, it’s alive! In the micro-cosmos of our body tissues movement is likewise vital to life- and can also contribute to death! Organ development, wound repair and immune defense all rely on the movement of single cells or cell groups. And in metastasis, renegade cells that escape from primary tumours find their way, by migration, to propagate in multiple sites elsewhere. Discovering how cells move is therefore important for understanding normal and pathological processes, with perspectives of bringing unwanted events under control. We already know that cell movement relies on the turnover of the protein filament systems comprising the so-called “cytoskeleton”. Our research is directed towards understanding the structural basis of cytoskeleton turnover and the underlying molecular mechanisms. To this end we are combining molecular biology techniques with live cell imaging technologies and electron microscopy, including electron tomography for 3D imaging of cytoskeleton networks.
