General fate map of Capitella teleta. (A-M) Stage 6 to 7 larvae ~5 days after labeling the first to fourth quartet micromeres. (N-R) Stage 6 to 7 larvae ~5 days after labeling the third and fourth quartet macromeres. In all panels, differential interference contrast (DIC) images are overlaid with red DiI fluorescent images. All images are of fixed larvae except for (D) and (H) and (I), which are of live animals. The arrow in (D) indicates a row of DiI-labeled ectodermal cells posterior to the prototroch. The blastomere labeled with DiI is indicated in the upper-right corner, and the view is indicated in the lower-left corner of each panel (dors = dorsal, vent = ventral). Anterior is to the left in all panels.
