Abstract

Neural stem cells (NSCs) in the developing neuroepithelium give rise, directly or indirectly, to all the neurons of the mammalian central nervous system (CNS). In addition, they generate other essential neural cells, mainly the two types of macroglial cells in the CNS: astrocytes and oligodendrocytes. This chapter focuses on the cellular and molecular aspects of neural stem cell biology during CNS embryonic neurogenesis, the process through which these initially multipotent cells undergo fate restriction steps that will eventually lead to all the neuronal subtypes. We describe neurogenesis mainly in the developing cerebral neocortex, although the principles highlighted here describe also many aspects of the development of other CNS regions. We take the rodent brain as the main model system, as many principal hallmarks of brain development are evolutionarily conserved between rodents and other mammals, including hominids. Key differences exist, however, and they are pinpointed where appropriate. We also highlight some areas of intense current research and mention ideas that could contribute to our understanding of CNS development and function.
