We report that two molecular markers correlate with a transient inhibition of neural crest cell entry into the dorsolateral path between the ectoderm and the somite in the avian embryo. During the period when neural crest cells are excluded from the dorsolateral path, both peanut agglutinin lectin (PNA)-binding activity and chondroitin-6-sulfate (C6S) immunoreactivity are expressed within this path. Both markers decline as neural crest cells enter. Moreover, both markers are absent after an… CONTINUE READING
