After providing basic background on transplantation, brain structure, and development, the book discusses Parkinson's disease, the use of transplants to influence localized brain functions, circuit reconstruction, and genetic engineering and other future technologies.

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.

Many diseases earlier considered to be incurable are now being treated with modern innovations involving fetal tissue transplants and stem cells derived from fetal tissues. Fetal tissues are the richest source of fetal stem cells as well as other varying states of differentiated cells and support or stromal cells. The activity of such stem cells is at their peak provided they are given the correct niche. Stem cells, as we know, are immortal cells with the capacity to regenerate into any kind of differentiated cell as per niche-guidance. As such, fetal tissues have the potential capacity to mend, regenerate and repair damaged cells or tissues in adults, when directly transplanted to the site of injury, or even when transplanted in some other site, because it may have a homing capacity to migrate to the site of the specific injured organ. This is a new area of translational research and needs to be highlighted because of its immense potential. This book will bring together the new work of prominent medical scientists and clinicians who are conducting pioneering research in human fetal tissue transplantation. This will include direct transplant of healthy fetal tissue into mature patients as well as in hosts with genetic diseases. Transplant techniques, donor-host interaction, cell and tissue storage, ethical and legal issues, are some of the many matters which the book will deal with.

Recent scientific breakthroughs, celebrity patient advocates, and conflicting religious beliefs have come together to bring the state of stem cell researchâ€"specifically embryonic stem cell researchâ€"into the political crosshairs. President Bush's watershed policy statement allows federal funding for embryonic stem cell research but only on a limited number of stem cell lines. Millions of Americans could be affected by the continuing political debate among policymakers and the public. Stem Cells and the Future of Regenerative Medicine provides a deeper exploration of the biological, ethical, and funding questions prompted by the therapeutic potential of undifferentiated human cells. In terms accessible to lay readers, the book summarizes what we know about adult and embryonic stem cells and discusses how to go about the transition from mouse studies to research that has therapeutic implications for people. Perhaps most important, Stem Cells and the Future of Regenerative Medicine also provides an overview of the moral and ethical problems that arise from the use of embryonic stem cells. This timely book compares the impact of public and private research funding and discusses approaches to appropriate research oversight. Based on the insights of leading scientists, ethicists, and other authorities, the book offers authoritative recommendations regarding the use of existing stem cell lines versus new lines in research, the important role of the federal government in this field of research, and other fundamental issues.

This book begins with a synopsis of experimental work underlying degeneration and recovery in the nervous system, which is then discussed in the context of strategies to repair the central nervous system (CNS) and peripheral nervous system (PNS). The major part of the book is given over to the approach involving the use of transplanted tissues to replace and restore disrupted neural networks. This experimental work has formed the basis for the emerging clinical trials employing neural grafts for diseases such as Parkinson's and Huntington's, which are discussed in detail. The book then goes on to discuss newer cellular strategies involving the manipulation of neural cells both in culture and genetically, an approach that may ultimately be employed in the clinical situation. Neural Repair, Transplantation and Rehabilitation is unique in bridging the gap from experimental studies to clinical trials, whilst also providing the non-specialist with a background in rehabilitation strategies as well as basic neuroscience. It is recommended for all those involved in the management of patients with degenerative and traumatic injuries to the nervous system.

Traumatic brain injury (TBI) remains a significant source of death and permanent disability, contributing to nearly one-third of all injury related deaths in the United States and exacting a profound personal and economic toll. Despite the increased resources that have recently been brought to bear to improve our understanding of TBI, the developme
