Fig. 6. Model of events needed for proper sympathetic ganglion formation.
Schematic model showing important events in a spatiotemporal pattern for
discrete sympathetic ganglion formation adjacent to the ventral edge of a
rostral somite. 1. Neural crest cells migrate from the neural tube
through the rostral somites. 2. Neural crest cells disperse adjacent to
the dorsal aorta. ephrinB1 expression is established in inter-ganglionic
regions between developing ganglia. 3. N-cadherin adhesion and
inhibitory ephrinB1 expression induce formation of discrete ganglia. A,
anterior; c, caudal somite; da, dorsal aorta; nc, notochord; nt, neural tube;
P, posterior; r, rostral somite.
