Cranial sensory ganglia neurons require intrinsic N-cadherin function for guidance of afferent fibers to their final targets.

ABSTRACT: Cell adhesion molecules, such as N-cadherin (cdh2), are essential for normal neuronal development, and as such have been implicated in an array of processes including neuronal differentiation and migration, and axon growth and fasciculation. cdh2 is expressed in neurons of the peripheral nervous system during development, but its role in these cells during this time is poorly understood. Using the transgenic zebrafish line, tg(p2xr3.2:eGFP(sl1)), we have examined the involvement of cdh2 in the formation of sensory circuits by the peripheral nervous system. The tg(p2xr3.2:eGFP(sl1)) fish allows visualization of neurons comprising the trigeminal, facial, glossopharyngeal and vagal ganglia and their axons throughout development. Reduction of cdh2 in this line was achieved by either crosses to
