Most biological cells have a fixed place in an organism. However, cells can become mobile and move through the body. This happens, for example, during wound healing or when tumour cells divide uncontrollably and migrate through the body. Mobile and stationary cells differ in various ways, including their cytoskeleton. This structure of protein filaments makes the cells stable, stretchable and resistant to external forces. In this context, -intermediate filaments- play an important role. Interestingly, two different types of intermediate filaments are found in mobile and stationary cells. ...
