Cell lineage and cell migration in the neural crest.
The neural crest is a transient embryonic structure whose cells migrate extensively before giving rise to a variety of differentiated cell types. Both intrinsic cell lineage information and environmental cues are thought to play a role in determining the fate of these cells. Early in development, these cells can be divided into distinct populations based on their axial level of origin. Cranial ...
متن کاملA vital dye analysis of the timing and pathways of avian trunk neural crest cell migration.
To permit a more detailed analysis of neural crest cell migratory pathways in the chick embryo, neural crest cells were labelled with a nondeleterious membrane intercalating vital dye, DiI. All neural tube cells with endfeet in contact with the lumen, including premigratory neural crest cells, were labelled by pressure injecting a solution of DiI into the lumen of the neural tube. When assayed ...
متن کاملNeural crest cell formation and migration in the developing embryo.
Neural crest cells arise from the neural tube shortly after its closure and migrate extensively through prescribed regions of the embryos, where they differentiate into most of the peripheral nervous system as well as the facial skeleton and pigment cells. Along the embryonic axis, several distinct neural crest populations differ both in their migratory pathways and range of derivatives. Wherea...
متن کاملXenopus neural crest cell migration in an applied electrical field
Xenopus neural crest cells migrated toward the cathode in an applied electrical field of 10 mV/mm or greater. This behavior was observed in relatively isolated cells, as well as in groups of neural crest cells; however, the velocity of directed migration usually declined when a cell made close contact with other cells. Melanocytes with a full complement of evenly distributed melanosomes did not...
متن کاملSemaphorin signaling guides cranial neural crest cell migration in zebrafish.
Cranial neural crest cells (NCCs) migrate into the pharyngeal arches in three primary streams separated by two cranial neural crest (NC)-free zones. Multiple tissues have been implicated in the guidance of cranial NCC migration; however, the signals provided by these tissues have remained elusive. We investigate the function of semaphorins (semas) and their receptors, neuropilins (nrps), in cra...
