neural crest

group of embryonic cells that are pinched off during the formation of the neural tube (the precursor of the spinal cord) but that do not remain as a part of the central nervous system. The cells of the neural crest migrate to numerous locations in the body and contribute to the formation of diverse structures, mostly associated with the nervous system. The factors determining their migration and differentiation are not known.
