A cell that, in the early stages of the brain, are generated from the ectoderm-derived neural epithelium and commit to differentiate into either neurons or radial glial cells. It is well known that radial glial cells have distinctive morphological characteristics and can act as neural progenitor cells (NPCs) or neural stem cells (NSCs), in addition to guiding the migration of differentiating neurons in the central nervous system.
