From: Addressing cancer invasion and cell motility with quantitative light microscopy
Illustration of protrusions and retractions for one cell from movie related to Fig. 3. (a) The cell at time-point 371 min; (b) the same cell at time point 381 min and (c) superimposed outlines with the protrusion in green and retraction in red. The field size is 128 × 135 µm. The common area occupied in both frames is in yellow. The green protrusion is the newly allocated area in the frame (b), and the red retraction is the withdrawn area allocated in the frame (a), which is no longer allocated in (b).
