During the development of the mammalian central nervous system, neural stem cells and
their derivative progenitor cells generate neurons by asymmetric and symmetric divisions.
The proliferation versus differentiation of these cells and the type of division are closely
linked to their epithelial characteristics, notably, their apical–basal polarity and cell-cycle
length. Here, we discuss how these features change during development from
neuroepithelial to radial glial cells, and how this transition affects cell fate and neurogenesis.
