The neural crest, the intriguing cell population that gives rise to a panoply of derivatives in the vertebrate embryo including the mesenchymal structures in the head, melanocytes and most of the peripheral nervous system still proves to be an important yet enigmatic developmental cell population to study, with applications in stem cell biology, cancer biology and clinical medicine. Albeit our knowledge base is rich due to a strong history of experimentation, the fact that we have yet to decipher so many key aspects of neural crest cell (NCC) behavior speaks to the challenging complexity of this transient yet vital cell population. With the advent of new fluorescent tracing techniques, we have reexamined the migratory behaviors and ultimate fate of ventrally migrating avian NCCs within a late wave of emigration and identified a subpopulation of lineally restricted NCCs who migrate to the contralateral dorsal root ganglia (DRG) and therein give rise to mitotically active progenitor cells that ultimately produce the majority of the nociceptive sensory neurons in the DRG. These data provide evidence for the fate prespecification of subsets of NCCs while still resident in the neural tube.
