the location of the caudal branchial arches below the migrating vagal neural crest , the transience of the neurofilament immunoreactivity in them , and the coincident transience of their neurogenic potential in vitro , suggested that the masses of neurofilament immunoreactive cells in the caudal branchial arches might be vagal neural crest-derived neuronal precursor cells en route to the pharynx and the rest of the gut .
