Idealized Lineal Relationships between the Major CNS Cell Types
In an effort to unify the studies of neural stem cells, we offer this diagram depicting the relationships between the cell types discussed. At the top is the embryonic CNS stem cell, which can self-renew and produce differentiated progeny, perhaps by a gradual restriction mechanism where intermediate cell types such as the O-2A progenitor or neuroblasts serve as the immediate precursors of the terminally differentiated cell types.
