Cell motility
Introduction
Motility is a biological term which refers to the ability to move spontaneously and independently. It can apply to either single-celled or multicellular organisms.
In cellular biology or biomedical engineering, motility often refers to directed cell movement down gradients established in biopolymers. Examples are:
- movement along a chemical gradient (see chemotaxis)
- movement along a rigidity gradient (see durotaxis)
- movement along a gradient of cell adhesion sites (see haptotaxis)
