Movie 7

Polarized actin-rich protrusions of migrating endodermal cells in control and mmp14a/b MO-injected embryos.
Confocal time-lapse experiments were performed on Tg(sox17:GFP-UTRN) control or mmp14a/b MO-injected embryos at TB, using a Zeiss LSM700 confocal microscope with a LD C-Apo 40×/NA 1.1 water objective. Images were acquired at 10-sec intervals, and movie plays at 5 frames/sec.
