Radial glial cells have two important functions.One is the "scaffolding" of newborn immaturity neurons,leading newborn immaturity neurons move to special area,and form each cortical-layer of central nervous system.Another is as an important neural stem cell,which is the main source of neuron and neural glial cells,providing native materials for the growth of central nervous system.This article discusses the history,definition and characters of radial glial cells.
