Limits of NC contribution to the zebrafish craniofacial skeleton.

<p>Diagrams depict the cartilage elements and bones that are NC-derived (green), and those that show no evidence of NC contribution, and are presumably derived from mesoderm (magenta). The diagram in A shows a dorsal view of the chondrocranium from an approximately 12 dpf larva. B is a side view of the bones of an adult skull, with some elements of the pectoral girdle also shown. C shows a dorsal view of the dorsal aspect of the adult skull. In D, the view is of the base of the neurocranium, with the pharyngeal skeleton removed. Skeletal elements are labeled according to the abbreviations in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0047394#pone-0047394-t003" target="_blank">Table 3</a>. Note that in all diagrams, some elements are omitted for the sake of clarity; drawings were modified from Cubbage and Mabee (1996) and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0047394#pone.0047394-Grandel1" target="_blank">[62]</a>.
