Video 3. Tracking mesoderm migration.
3D snapshots of confocal stacks from a T-Cre; mTmG embryo dissected at E6.75 (Early Streak stage) and imaged for 180 min, with manually highlighted cells tracked throughout the time lapse. Video shows highlighted cells first, then the original images (membrane GFP, in green) in a looping fashion for comparison. All other cells express membrane dtTomato (grey). Lateral orientation with anterior to the left (scale bar: 50 μm).
