Developmental comparison using space filling models. In both images, the time point corresponds to the point where the AB sublineage contains 64 cells. As in Figure 5, the wild type embryo is on the left and the embryo with lit-1 inhibited is on the right. The E lineage cells have not migrated to the interior in the RNAi embryo. Cell migration generally has not proceeded in the normal way. These are ventral views with anterior on the left. The nuclei are color-coded so the main lineages can be distinguished: ABa daughters in gray; ABp in white; E in red; MS in blue; C in yellow; D in pink; germ line in green.
