Shape-dependent cell migration and focal adhesion organization on suspended and aligned nanofiber scaffolds

In the body, cells dynamically respond to chemical and mechanical cues from the extracellular matrix (ECM), yet precise mechanisms by which biophysical parameters (stiffness, topography and alignment) affect cell behavior remain unclear. Here, highly aligned and suspended multilayer polystyrene (PS) nanofiber scaffolds are used to study biophysical influences on focal adhesion complex (FAC) arrangement and associated migration behavior of mouse...
