In larval stages, expression was most evident in the pharyngeal muscle. There may also have been neuronal expression in the larva, but this was hard to discern in the pharynx region. However, in adults, lat-1
expression appeared to be lost from the muscle but was expressed in anterior neurons, both extra-pharyngeal and pharyngeal, including one neuron in the terminal bulb and neurons of the corpus, with projections into the isthmus. Notably, in the pharynx of adult animals, lat-1
is expressed in neurons rather than muscle.
