Video illustrates the overall complexity of phagocytosis with live cell timelapse high-content microscopy imaging even close-up in phase contrast channel alone. Time-lapse video is same close-up region as shown in Movie 3, except only phase contrast channel is displayed. Individual frames 1 (0 min), 20 (~30 min), 40 (~60 min), and 60 (~90 min) are depicted in Fig.2A Phase.
