Antero-dorsal view on the head and anterior trunk region of a zebrafish embryo (Danio rerio) on the egg surface.
Summary[edit]
| Description |
English: The embryo is drawn in grey, the prospective eye regions white. Dashed contours show the previous location of the embryo. The location of the body on the back side of the egg is drawn dotted. Compensatory movements can be observed between 14:40 and 16:40 p.f. During this period those cells that will form the eyes migrate anti-clockwise (perspective of the embryo), whereas the future mid- and hindbrain cells migrate clockwise between 15:15 and 16:40 h (arrows). The right eye is initially invisible because it is hidden below the cells that will form the forebrain. The first 5 frames are interleaved by 30 min, the last one is 10:15 h later. Drawn from Keller et al. (2008: supplementary movie no. 2).
