A 3D reconstruction by confocal imaging of the distal region and node of an embryonic day 8.0 embryo. Primary cilia that express ARL13B-mCherry (red) are broadly distributed in both the long cilia of the node (the pit at the center of the Video) and in cells of all three germ layers. Centrioles are marked with Centrin2-GFP (green).
