Powerful microscope captures first image of nanoscaffold that promotes cell movement

Using one of the most powerful microscopes in the world, scientists have identified a dense, dynamic and disorganized actin filament nanoscaffold — resembling a haystack — that is induced in response to a molecular signal. This is the first time researchers have directly visualized, at the molecular level, a structure that is triggered in response to a cellular signal — a key finding that expands our understanding of how cells move.
