Abstract

Cell migration is a fundamental process in the development and homeostasis of multicellular organisms. It is also central to many pathologies and it is especially important for metastatic dissemination. When migrating, cells use adhesion structures to push on their substrate in order to move forward. We recently showed that clathrin coated structures, primarily known as endocytic structures, can also serve as adhesion structures. In this manuscript, I show that some ligands internalized through clathrin mediated endocytosis can also bind to the extracellular matrix and orient cell migration using adhesive clathrin structures.I first showed that ligand-decorated collagen fibers are associated with more clathrin structures and more protrusion...
