develops_from develops from glioblast migratory neural crest cell Schwann cell precursor 2010-09-24T02:06:10Z A giioblast cell that develops from a migratory neural crest cell. The SCP is embedded among neurons (axons) with minimal extracellular spaces separating them from nerve cell membranes and has no basal lamina. In rodents SCPs are the only cells in the Schwann cell linage that expresses Cdh19. tmeehan cell Schwann cell precursor cell progenitor cell
