Fig. 5. Distribution and numbers of the three orientations of division shown by timelapse analysis. (A) Still images from one movie are labelled to show the orientation each cell is about to undergo (see Movie at http://dev.biologists.org/supplemental/) (blue indicates parallel, green indicates oblique and red indicates perpendicular). (B) Percent of each orientation of division from the analysis of 10 timelapse movies. Number of cells refers to the cell-stage of the embryos. (C) Variable distribution of different orientations of division in 4x 128-cell embryos. Dorsal is towards the top. (D) Percent of each type of division that occurs in all superficial daughters of the left/dorsal (LD), right dorsal (RD), left ventral (LV) and right ventral (RV) blastomere (left), from eight-cell up to the 1024-cell stage.
