The story of mammalian neural transplantation really begins eighty-one years ago. In Chicago in December of 1903, a 34-year-old physician, Elizabeth Hopkins Dunn, working as a research assistant in neurology, initiated a series of experiments to examine the ability of neonatal rat cerebral tissue to survive transplantation into the brain of matched littermates. Out of 46 attempts, four clearly successful grafts were identified. The publication of Dunn's results in 1917, the first credible report to demonstrate the feasibility of mammalian CNS transplants, generated little interest. In fact, the next significant experiment in this field did not appear until 1930. The field continued to grow slowly and quietly as investigators gradually realized the value of neural trans plantation to study problems of development and plasticity in the mammalian nervous system. With the discovery in 1979 that grafted neurons were capable of appropriate and functional interactions with the host brain, interest in neural transplantation esca lated sharply. The extraordinary opportunities created by using functional neural trans plants in investigating basic issues in neurobiology, as well as the clinical implications, excited both scientists and the public. The popularity of neural transplantation has been growing rapidly in the past five years and shows no signs of abating. The present volume was designed to meet two needs created by the rapid growth of this subdiscipline of neurobiology. The first was to provide a thorough review of the experimental foundations of neural transplantation.

This state-of-the-art review links the experimental data into a cohesive and critical account of CNS regeneration. Research findings are discussed in terms of their relevance to one (or more) of thirteen hypotheses concerned with regeneration in the mammalian CNS. Research findings reviewed include: regeneration in developing mammals and in submammalian vertebrates, the use of transplants and/or pharmacological treatments, in vitro studies on neurotrophic and neurite promoting factors and their potential relevance to CNS regeneration in vivo, and in vitro studies on the types of glial cells that may be responsible for enhancing or suppressing axonal re-growth.

During the last decade research on neural transplantation in mammals has grown extensively, and has attracted the attention of many young inquisitive scientists. This growth, as the critics point out, has been somewhat random, and has resulted neither in the formulation of basic concepts nor in any other significant achievement. For instance, they question-how is it possible to jump into functional research with clinical bearing when the basic morphological work has not yet been conducted? The criticism, objectively speaking, is valid and is supported by the fact that every investigator who has stepped into this unex plored field of neurosciences has formulated questions in his own way, has followed his own "model" oftransplantation, and has arrived at his own unique conclusions. The potential danger, as the critics emphasize, in this type of approach lies in that instead of evolving into a scientifically solid and valuable field of research, it may end in a confusing and conflicting mass of questionable claims and subjective opinions. The present situation, very likely, is a reflection of unrestrained enthusiasm and imaginativeness of the investigators, and the demands of the times for the so-called "newsworthy" and "breakthrough" publications. Despite these limitations, two important facts have been estab lished in this field. First, as far as transplantation of neural tissues per se is concerned, what was considered impossible by some critics about 10-12 years ago has been shown to be possible.

This volume is based on a meeting of the Fondation IPSEN, held in Paris on Sep tember 18, 1995 to address the main issues of nervous system stem cells biology. Cell replacement in the adult mammals is not unusual outside the nervous sys tem. In fact, the nervous system is unique in lacking the ability to replace cells, following damage. Most neurons, in the adult central nervous system are termin of the organism and are not replaced ally differentiated, exist through the life when they die. There are, however, regions of the postnatal brain that continue to produce new neurons, but the fate and longevity of those cells are not well known. Evidence exists that small populations of neurons continue to be born in the adult ventricular zone, olfactory epithelium and hippocampus. In the adult hippocampus, newly born neurons originate from putative stem cells that exist in the sub granular zone of the dentate gyrus. Progeny of these putative stem cells differentiate into neurons in the granular layer within a month of the cells' birth, and this late neurogenesis continues throughout the adult life of the rodent. By understanding the nature of progenitor cells present in the embryonic and adult brains, the change in their population dynamics during development, and the factors that influence their proliferation, fate choice and differentiation, it may be possible to develop a strategy to manipulate cells in situ to treat neuro degenerative diseases or the injured adult brain.
