(b) Time-lapse images of LifeAct-KCs at the level of cell exit from 3.0-µm micropores. Representative images are shown at 30-minute time intervals. Time stamp shows hour:minute. Arrows indicate the cells that exit from the pores and expand under the membrane. Arrowheads indicate the cells that show reciprocating movement. Scale bar: 20 µm. (c) Schematic diagram of LifeAct-KCs cultured on a microporous membrane. Observation at the level of cell entry into the micropores. (d) Time-lapse images of LifeAct-KCs at the level of cell entry into 3.0-µm micropores. Representative images are shown at 5-minute intervals. Time stamp shows hour:minute.
