In the present work, processes of cell proliferation, cell death, neurogenesis, and gliogenesis in the mouse hippocampus were studied. The mapping of distribution of hippocampal mitoses and counting of their number allowed a more precise definition of the data concerning the disposition and age reduction of proliferative sites in Ammon's horn and the dentate gyrus in the mouse. As a result, the following generalized scheme of development and age reduction of the germinal zones in the mouse hippocampus has been suggested. 1. Ammon's horn a) The ventricular zone, from the beginning of formation of the hippocampus (Ell) until E20 b) The suprafimbrial zone, from El6 until P7 2. Dentate gyrus a) The prime germinal zone ("the anlage of the dentate gyrus" of Stanfield and CowanI979b), from E15 until P3 b) The proliferative zone of the hilus, from P3 until Pl4 c) The subgranular zone, from P3 until adult age The adduced scheme needs some comments: 1. In the hippocampus (as well as in other formations of the developing brain), primary precursors of all types of cells of neuroectodermal origin are represented by cells of the ventricular zone. They give rise to cells of secondary germinal zones in the dentate gyrus and Ammon's horn and are direct precursors of the majority (if not of all) neuronal cells in Ammon's horn, the earliest originating generations of neurons in the dentate gyrus, hippocampal radial glial cells, and, evidently, of a considerable part of astroblasts and oligodendroblasts in Ammon's horn.

Studies on cell kinetics in untreated animals have for the most part been done on or gans in which many proliferating cells can be found. In general the proliferating cells have been identified either in histologic sections as mitoses or by autoradiography as labeled interphase cells following the injection of a labeled precursor of DNA, such as 3H_ or 14C-thymidine (TdR). A great many proliferating cells can be observed in the rat and mouse brain during the embryonic period and for a short time after birth, and many studies on cell kinetics have been performed for this phase of life. By contrast, very few proliferating cells are found in the brain of adult rodents (except for the subependymallayer, see below). As a result, only isolated studies have been done on cell kinetics during this period. Al though there is an increase in proliferating cells in adult animals which had been pre treated (e g. , by wounding, X-irradiation, viral infection, withdrawal of water), this proliferation too has not been investigated in detail. A number of studies have been done since 1959 on the proliferation of cells in the sub ependymal layer of the lateral ventricles of the forebrain. This cell type is well suited for such investigations because mitoses can be found there even in animals which are quite old. Since the studies ofLe blond and co-workers (Walker and Leblond 1958 ;Messier et al.

Stem Cells and CNS Development critically reviews recent findings on stem cells, their involvement in neurogenesis and gliogenesis, and the therapeutic implications of these findings. It defines by consensus the classes of stem cells in the nervous system, compares their similarities and differences, discusses the gains made in identifying human homologs of neural stem cells, and describes how these cells are beginning to be used for therapeutic purposes. Comprehensive and cutting-edge, this book provides all developmental scientists and neurobiologists not only an authoritative account of the current results in neural stem cell research, but also an incisive review of the rapidly emerging therapeutic uses of stem cells.

This book is a collective work of international experts in the neural stem cell field. The book incorporates the characterization of embryonic and adult neural stem cells in both invertebrates and vertebrates. It highlights the history and the most advanced discoveries in neural stem cells, and summarizes the mechanisms of neural stem cell development. In particular, this book provides strategies and discusses the challenges of utilizing neural stem cells for therapy of neurological disorders and brain and spinal cord injuries. It is suitable for general readers, students, doctors and researchers who are interested in understanding the principles of and new discoveries in neural stem cells and therapy.

This book builds a novel bridge from molecular research to clinical therapy. This approach reveals the functional features of neurons and glia in the particular context of vulnerability and self-protection, intracellular properties and extracellular matrix. Arising from this platform, this volume unfolds the molecular and systemic processes underlying migration disorders, axonal injury, repair and regeneration.
