V2 cell-shapes and cell-division timing.
(a) Nine TgBAC(vsx1:GFP)nns5 zebrafish embryos at the 16-somite stage. Shown are dorsal views of trunk spinal cord region with anterior side of the embryo on the left. GFP+ V2 cells are color-coded according to the times when they begin to divide. Scale bar, 50 μm. (b) Variability in V2 cell division timing. Color codes are the same as in a. See also Supplementary Fig. 1 and Supplementary Movie 1. (c) Shapes of V2 cells in relation to their division timing. Stacked images of individual V2 cells in a. are shown. Images are dorsal view (relative to the whole embryo) with the apical side of the cell on the left. Scale bar, 10 μm.
