KG1a cell retracting a magnupod. Four images were taken at various time intervals. Image (a) was taken at t = 0, (b) at t = 14 seconds, (c) at t = 75 seconds, and (d) at t = 150 seconds. The corresponding lengths of the magnupod are 77, 58, 42, and 14 μm, respectively, resulting in a retraction rate of approximately 0.4 μm/s. The scale bar is 50-μm long.
