Composite of outlines of actual cell membranes moving to a pipette filled with a chemoattractant and position in the upper right hand corner. The outlines are color coded to show the time evolution. The inset shows a sequence of images of a chemotaxing cell in which both the actin network (red, and responsible for protrusive forces) and myosin (green, and responsible for contractile forces) is marked by a fluorescent protein. For more details, please see the Research section or our publications.
