Some Embryo Stem Cell Explorations

From the many experimental studies conducted at present, embryo stem cell research is definitely one of the most controversial. The use of human embryos as the biological material necessary to the extraction of stem cells has caused a wave of protests and actions from pro-lifers who consider such procedures a form of homicide. The problem is that starting from a mere embryo stem cell formation, scientists are now capable of creating all sorts of therapies and cures to deal with diseases and injuries that have always been diagnosed as irrecoverable. There are other sources for stem cells besides embryos, such as adult tissues or regular somatic cells, but the possibilities they bring are limited.

Any embryo stem cell that lives in a blastocyst (the resulting cell after the fertilization of an ovum by a spermatozoon) has the infinite potential of transforming into any of the functional body cells that are specialized for a certain body task. All the complex body structures afterwards evolve from this primary cellular grouping that divides in an organized manner. The benefits and successes of science in this research domain seem to be incredibly valuable, but many people wonder whether we are neglecting the rights of human life in its very early stages of development. From this point of view any research conducted on embryos is a violation of the sacred of the living.

Medical scientists agree unanimously that the embryo stem cell research could alleviate incredible sufferance and treat diseases that have no solutions in the traditional medical perspective. Scientists are also making efforts to come up with some substitutes for any embryo stem cell necessity by identifying other sources of stem cells. For example, the amniotic liquid seems to be very rich in such cell formations, and the sample collection poses no threat to the fetus. Then, another recent discovery has been the possibility for the reversed function of normal somatic cells that can be reprogrammed into becoming stem cells once again.

Last but not least, we ought to refer to the great success in embryo stem cell research that consists in the collection of stem cells from an embryo without harming it during the process. This achievement is definitely a novelty but it definitely solves the ethical concerns that made the foundation for so many objections. Nevertheless, there are lots of other things to consider and implement in modern medicine, before embryo stem cell research may solve the issue of the chronic diseases decimating humanity.

God and the Embryo: Religious Voices on Stem Cells and Cloning $29.95 Discussions and debates over the medical use of stem cells and cloning have always had a religious component. But there are many different religious voices. This anthology on how religious perspectives can inform the difficult issues of stem cell research and human cloning is essential to the discussion. Contributors reflect the spectrum of Christian responses, from liberal Protestant to evangelical to Roman Catholic. The noted moral philosopher Laurie Zoloth offers a Jewish approach to cloning, and Sondra Wheeler contributes her perspective on both Jewish and Christian understandings of embryonic stem cell research. In addition to the discussions found here, God and the Embryo includes a series of official statements on stem cell research and cloning from religious bodies, including the Roman Catholic Church, the Orthodox Church in America, the United Methodist Church, the Southern Baptist Convention, the United Church of Christ, the Presbyterian Church (USA), and the Union of Orthodox Jewish Congregations of America and the Rabbinical Council of America. Human Cloning and Human Dignity: An Ethical Inquiry, from the statement of the President's Council on Bioethics, concludes the book. The debates and the discussions will continue, but for anyone interested in the nuances of religious perspectives that make their important contributions to these ethically challenging and important dialectics, God and Embryo is an invaluable resource.

Manipulating the Mouse Embryo $165 Regarded as the Bible of mammalian embryo manipulation techniques since the 1986 publication of the first edition of Manipulating the Mouse Embryo: A Laboratory Manual, the third edition of this essential laboratory resource has now been completely reorganized, rewritten, and updated by a new cast of authors. The result is a compilation of new, cutting-edge protocols that include embryonic stem cell production and genetic manipulation, mouse chimeras, mouse cloning, assisted reproduction strategies (including intracytoplasmic sperm injection and in vitro fertilization), whole embryo culture systems, electroporation, embryo and gamete cryoperservation and rederivation, and gene expression, as well as more extensive background information on the use of these techniques. This book is the premier authoritative and comprehensive source of technical and theoretical guidance for mouse developmental biologists and geneticists and is an essential resource for newcomers to these fields.

The Stem Cell Divide $15.8 There has been much recent debate about the merits, dangers, and nature of stem cell research. Some see in it the answer to every debilitating disease known to man, while others see it as a step away from human cloning. The Stem Cell Divide does not take sides, and the author debunks the distortions and exaggerations that come from every camp. This book does not tell readers what to think, but gives them the facts necessary to form their own opinions about one of the most divisive, complex, and potentially life-changing developments in history.

Blood Stem Cell Transplantation $564 Blood Stem Cell Transplantation conveys the excitement that accompanies the newest developments in hematopoietic stem cell transplantation. Some of the applications that stand to impact this field most significantly are based on recent advances in the biological sciences, as demonstrated by the chapters on gene therapy, on the detection of minimal residual disease using molecular techniques, and on the use of radioimmunoconjugates targeting lymphoma and leukemia-associated antigens. Others are the results of clinical observations - e.g., the association between graft-versus-host- disease (GVHD) and durable remissions that have led to creative clinical experiments such as donor leukocyte infusions (DLI). Attempts to unravel the biological events that underlie the responses seen in patients with relapsed chronic myelogenous leukemia treated with DLI are likely to provide the basis for future refinements in this clinical approach. Hopefully, improved response rates and reduced toxicity will result. The power of the immunologic response in controlling malignant disease is underscored in the chapter on post-transplant immunotherapy. The complex immunologic process that results in clinical GVHD may be dissected and engineered to provide clinical benefits that include, in addition to its antineoplastic effects, the amelioration of its clinical manifestations. Better control of GVHD with less global immunosuppression will facilitate the use of mismatched and unrelated donors. This area of investigation perfectly illustrates the continued interplay between the laboratory and the clinic. The continued cross-fertilization of ideas between immunologists, molecular biologists and clinicalinvestigators is likely to yield important advances in this field for years to come. Possible applications of stem cell transplantation continue to grow with the identification of alternative sources of stem cells and the potential to engineer and/or expand the graft. Although the use of unrelated and mismatched donors continues to increase, the possibilities associated with umbilical cord blood transplantation are legion, especially if stem cells can be expanded ex vivo to provide grafts for full-sized adults. Using techniques in which contaminating malignant cells may be eliminated from autografts through positive selection, autologous transplantation may prove highly effective, especially when coupled with post-transplant immunotherapy. Some of these same methodologies have helped facilitate the use of autologous grafts for transplantation in patients with chronic myelogenous leukemia without allogeneic donors.Advances in the supportive care of transplant patients, including the pretransplant identification of those at risk from pulmonary complications and the use of cytokines to speed engraftment, have reduced morbidity and mortality to such a degree that it is appropriate to consider high-dose therapy and stem cell reconstitution in patients with nonmalignant diseases.

Embryo Research in Pluralistic Europe $129 Recent advances in techniques and understanding in the fields of genetics, embryology and reproductive biology have opened up new ways to treat a wide range of medical problems. They range from new options for infertility treatment and pre-implantation genetic diagnosis to stem-cell-based therapies for debilitating diseases. Since all these approaches involve the manipulation of human gametes, embryos or embryonic cells, and could also permit more contentious uses, they have stimulated a controversial debate as to what aims are desirable and to what extent experiments on human embryos are morally permissible, if permissible at all. The situation is further complicated by the fact that scientific projects are increasingly realized through international co-operation and that patients are increasingly ready to seek morally contentious medical treatment wherever it is available and thus to bypass national legislation. In view of this situation the Europdische Akademie assembled a temporary interdisciplinary project group in which scientists from universities and non-university research organizations in Europe working on the relevant subjects were brought together and charged with establishing a knowledge base and providing suggestions for long-term solutions that would be acceptable for society. Presented here are the results of this project, ranging from a discussion of the theoretical and practical possibilities in human-embryo experimentation and its alternatives in research on adult stem cells, a comparison of the situations and prospects of regulation of embryo research in Europe, a survey of European public attitudes, and a philosophical analysis of the arguments and argumentativestrategies used in the debate.

Stem Cells $28.45 Few scientific breakthroughs have generated as much controversy as stem cell research. Some see stem cell research as the cure-all for the diseases of modern society--heart disease, Alzheimer's, diabetes, and Parkinson's disease. Yet others question the ethics of stem cell research and worry about its future paths. Stem Cells explains the science behind the research, describes the possibilities stem cell therapies, and analyzes the basis of the controversy that surrounds what may be tomorrow's miracle cure.
