Vesicle sedimentation a: pear shape, full process from departing to landing, t= 0s, 0:57 s, 2:22 s, 4:46 s, 5:08 s, 6:28 s, shapes are fluctuating. b: short tube, full process, t=0s, 0:24s, 1:04s, 1:49s, 2:51s, 4:38s, 6:14s. c: landing process from stationary shape to settled vesicle, t=4:40s, 5:32s, 7:04 s, 8:30s, 9:12s, 12:00s. d: departing of a vesicle and tube growth (time between image = 1s) e) landing of a vesicle with tube retraction (60s, 76 s, 84s, 90s, 92s, 93s).
