Ethical controversy over transplantation of human fetal tissue has arisen because the source of tissue is induced abortions. Opposition to such transplants has been based on various arguments, including the following: rightful informed consent cannot be obtained for use of fetal tissue from induced abortions, and fetal tissue transplantation might result in an increase in the number of abortions. These arguments were not accepted by the National Institutes of Health (NIH) Human Fetal Tissue (...) Transplantation Research Panel. The majority opinion of the panel stated that abortion and fetal tissue use are entirely separate issues, and that tissue use is ethically acceptable because it can be morally insulated from the issue of abortion. In support of this view, panel members and others have replied to the arguments put forward by opponents of fetal tissue use. However, replies to the two arguments mentioned above have been unsatisfactory, and the shortcomings of those replies are identified herein. Examination of the arguments pro and con suggests that fetal tissue use cannot be completely insulated from the issue of abortion. Thus, in seeking an ethical justification for fetal tissue transplantation we must consider reasons other than those put forward by the NIH panel. In this paper it is argued that whatever wrong is involved in using fetal tissue from induced abortions must be balanced against the benefits for patients, and it is on this basis that fetal tissue transplantation can be ethically justified.

Neural fetal tissue transplantation offers promise as a treatment for devasting neurologic conditions such as Parkinson's disease. Two types of issues arise from this procedure: those associated with the use of fetuses, and those associated with the use of neural tissue. The former issues have been examined in many forums; the latter have not. This paper reviews issues and arguments raised by the use of fetal tissue in general, but focuses on the implications of the use (...) of neural tissue for basic concepts of personnood and personal identity.

Currently, brain tissue transplantations are being developed as a clinical-therapeutic tool in neurodegenerative diseases such as Parkinson's or Alzheimer's disease. From an ethical point of view, distinguishing between the preservation and an alteration of personal identity seems to be central to determining the scope for further application of brain tissue transplantation therapy. The purpose of this article is to review "standard" arguments which are used on the one hand by proponents to prove preservation of personal identity and (...) by opponents on the other hand to prove that brain tissue transplantation results in an altered personal identity. Proponents and opponents are shown to use the same arguments, albeit with different presuppositions. These presuppositions concern the meaning of the term "identity", either numerical or qualitative, the definition of brain identity, either structurally or functionally, and the relationship between mental states, psychological functions and neurophysiological properties as criteria for personal identity. Furthermore the respective neurophysiological, clinical and philosophical evidence for the different presuppositions are discussed. It is concluded that evaluation of personal identity in brain tissue transplantation should not only rely on the "standard" arguments but, additionally, neurophysiological, clinical and philosophical implications should be discussed.

The prospect for widespread therapeutic use of human fetal tissues has aroused strong emotions and prompted several objections. Fetal tissue transplantation circumscribed by medical and moral limits will not erode important ethical values, but the pace of scientific research must not preempt public debate and a verdict consistent with societal values.

Two competing intuitions have dominated the debate over facial tissue transplantation. On one side are those who argue that relieving the suffering of those with severe facial disfigurement justifies the medical risks and possible loss of life associated with this experimental procedure. On the other are those who say that there is little evidence to show that such transplants would have longterm psychological benefits that couldn’t be achieved by other means and that without clear benefits, the risk is (...) simply too great. Ethicists on both sides have called for more analysis of the link between the face and personal identity in order to get a better grasp on potential gains and losses. This paper responds to that call by looking at contemporary philosophical analyses of the relation between organ transplants and personal identity and between the human face, human dignity, and human vulnerability. It is argued that the face matters not because it is the unique marker of our identity, but because of its role in the intersubjective constitution of moral identity and human dignity. (shrink)

As the debate about research on foetal tissue transplantation progressed, medical scientists learned more about the procedure and its potential for helping persons with degenerative brain disorders such as Parkinson's disease. Increased scientific knowledge significantly influenced the political process, yet it did not by any means resolve the debate. Rather, increased medical evidence served as a lens which focused discourse on particular issues related to foetal research, such as the details of obtaining informed consent, as well as technical (...) matters related to tissue transplantation, for example, that the creation of a tissue bank was unreasonable, and that foetuses of certain ages were required for the procedure. This increased focus changed the character of the debate on foetal tissue transplantation research, and convinced some law-makers that they should encourage financial support for the research despite their anti-abortion political views.The heart of the stalemate on transplantation research lay in rigid attachment to particular arguments, which in turn resulted in the disunity of the participants; this was compounded by the lack of persuasive scientific evidence that foetal tissue transplantation could significantly benefit those with Parkinson's disease. Privately supported clinical studies answered several important clinical questions while the ban on federal support remained in effect, however, and increased scientific knowledge was soon followed by an increasingly clear analysis of the relevant issues. By the time federal support for the research was permitted, the arguments of all of the interest groups had been altered by the findings of privately supported studies.As research continues under the auspices of a somewhat more permissive administration, these refined arguments and attitudes may continue to contribute to a stronger and more clearly defined public policy.

The therapeutic prospects withregard to the retrieval and research use of hEScells appear to function as a catalyst for theintroduction of less restrictive regulationsconcerning research with spare embryos, atleast in some European countries. It remains tobe seen whether the prospect of treatingpatients suffering from serious disorders withtransplants produced by therapeutic cloningwill decrease the societal and moral resistanceto allowing the generation of embryos for`instrumental' use.

The architecture of the fetal tissue transplant controversy is similar to that of many bioethical debates, with a novel twist because of the contested status of the fetus and abortion. Respect for the needs of sick patients appears to conflict with respect for prenatal human life and larger societal concems.

This article focuses on the deliberations of the National Institutes of Health Human Fetal Tissue Transplantation Research Panel in 1988. It explores various arguments for and against the use of fetal tissue for transplantation research, following elective abortion, and for and against the use of federal funds for such research. After examining the relevance of various positions on the moral status of the fetus and the morality of abortion, the article critically examines charges that such research, (...) especially with federal funds, would involve complicity in the moral evil of abortion, would legitimate abortion practices, and would provide incentives for abortions. Finally, it considers whether the donation model is appropriate for the transfer of human fetal tissue and whether the woman who chooses to have an abortion is the appropriate donor of the tissue.

One common objection to fetal tissue transplantation (FTT) is that, if it were to become a standard form of treatment, it would encourage or entrench the practice of abortion. This claim is at least factually plausible, although it cannot be definitively established. However, even if true, it does not constitute a compelling ethical argument against FTT. The harm allegedly brought about by FTT, when assessed by widely accepted non-consequentialist criteria, has limited moral significance. Even if FTT would cause (...) more abortions to be performed, and abortion is taken to be a serious moral wrong, this is not sufficient in itself to make FTT wrong. (shrink)

The cornea was the first human solid tissue to be transplanted successfully, and is now a common procedure in ophthalmic surgery. The grafts come from deceased donors. Corneal therapies are now being developed that rely on tissue from living-related donors. This presents new ethical challenges for ophthalmic surgeons, who have hitherto been somewhat insulated from debates in transplantation and donation ethics. This paper provides the first overview of the ethical considerations generated by ocular tissue donation from (...) living donors and suggests how these might be addressed in practice. These are discussed in the context of a novel treatment for corneal limbal stem cell deficiency. This involves limbal cell grafts which are transplanted, either directly or after ex vivo expansion, onto recipient stem cell-deficient eyes. Where only one eye is diseased, the unaffected eye can be used as a source of graft tissue. Bilateral disease requires an allogenic donation, preferably from a genetically related living donor. While numerous papers have dealt with the theory, surgical approaches and clinical outcomes of limbal stem cell therapies, none has addressed the ethical dimensions of this form of tissue donation.

The ecofeminist critique of dualism is applied to a consideration of two alternative paths that we might take in transplantation medicine: the utilization of organs and tissues taken from nonhuman animals, and/or further development of techniques for employing human organs and tissues, including human fetal tissue. It is concluded that from an evolutionary perspective, the assumption of a vast value disparity between human and nonhuman life is untenable, and from a moral point of view the establishment of yet (...) another institution based on a dualistic opposition between human life, postulated to be of ultimate value, versus devalued, disposable "other" life is unacceptable. We are urged to forego xenotransplantation and instead take responsibility for whatever manipulations we choose, respectfully, to make with life that is already valued as "self" rather than "other.".

Fetal tissue transplants have now been successful in primates, raising the possibility of treatment for Parkinson's disease and other chronic illnesses. Whether or not abortion is morally justified, use of human fetal tissue for research or therapy is justified in certain circumstances. The rationale, both for permitting transplantation of fetal tissue and for limitations in exercising the technology, is based on the same set of ethical principles that supported restrictive legislation in the past: respect for autonomy (...) and a balancing of harms and benefits that gives priority to those most affected.

The urochordates, whose stem groups may have included the direct predecessors of the chordate line, serve as an excellent model group of organisms for a variety of scientific disciplines. One taxon, the botryllid ascidian, has emerged as the model system for studying allorecognition; this work has concentrated on the cosmopolitan species Botryllus schlosseri. Studies analyzing self–nonself recognition in this colonial marine organism point to three levels of allorecognition, each associated with different outcomes. The first level controls natural allogeneic rejections and (...) fusions, in which blood‐shared chimeras are formed. The second level leads to morphological resorption of partners within chimeras while the third allows the development of somatic and germ cell parasitic events. Recent studies on multi‐chimeric entities formed in allogeneic fusions reveal evolutionary links between allorecognition, stem cell biology and ecology. Thus, the Botryllus system generates perspectives from different biological disciplines to yield a unique life history portrait. BioEssays 24:730–740, 2002. © 2002 Wiley Periodicals, Inc. (shrink)

The procurement of fetal tissue for transplantation may promise great benefit to those suffering from various pathologies, e.g., neural disorders, diabetes, renal problems, and radiation sickness. However, debates about the use of fetal tissue have proceeded without much attention to ethical theory and application. Two broad moral questions are addressed here, the first formal, the second substantive: Is there a framework from other moral paradigms to assist in ethical debates about the transplantation of fetal tissue? (...) Does the use of fetal tissue entail cooperation in abortion? To answer these questions I develop a theoretical framework by combining the paradigm of just-war reasoning with canons governing the use of cadaverous tissue. The kinds of safeguards provided by this paradigm allow fetal tissue to be procured without the taint of association with abortion. Central to solving the problem of cooperation is the distinction between intending and foreseeing a moral misdeed. Fetal researchers may foresee fetal death in elective abortions without intending such deaths to occur. Thus, even those who object unequivocally to elective abortion may condone the procurement of fetal tissue, if sufficient reason exists.

Tissue typing (TT) is a recent and controversial scientific advance. Whilst its current applications can easily be described as protherapeutic and within the realms of preventative medicine,1 its specificity and potential are often characterized as the tip of the eugenic iceberg: undermining the very basis of individual autonomy and identity in an inevitable march towards the perfect society:2 In addition to arguments concerning societal harms flowing from TT, significant concerns have also been raised concerning harms to the future child (...) born as a result. In the context of current legislation and policy, this article examines two aspects of arguments concerning harm to the future child: those relating to psychological harms, and those arguing that TT is contrary to the future child’s best interests.3The article examines the moral basis for arguments concerning harm to the future child. It proposes that arguments concerning psychological harm may overlook or minimise the potential benefits flowing from the broader social, familial context into which the child is born. These arguments may be countered, or at least balanced, by considering the future child in this context. In relation to arguments that TT is contrary to the future child’s best interests, the paper examines a non-standard consideration of best interests. It argues that this standard should be used in considering whether or not TT for bone marrow transplant is harmful to the future child, thereby extending moral consideration of interests to intra-familial interests and outcomes. On this basis, it can be argued that TT is not contrary to the interests of the future child. The paper concludes by noting a potential tension between the first guiding principle of the Infertility Treatment Act 1995 (Vic) and the current Victorian policy on TT. (shrink)

In this article Mr Tam Dalyell mp uses extracts from the speech1 he made in the House of Commons on 11 December 1974 to reiterate his reasons for persisting in his attempts to have formulated in law the right of hospitals to take such organs from a dead person as might be useful unless before death potential donors (all of us) had stated that they did not consent. Details of those objecting would be registered on a central computer.

Legislation that authorises controversial organ procurement strategies but ignores respect for autonomy is flawed in principle and predictably unworkable in practiceThe UK Human Tissue Act 2004,1 designed to regulate all activity involving human tissue, organs, or bodies, was introduced in the House of Commons in December 2003, received Royal Assent on 15 November 2004,2 and has been partially implemented by Commencement Orders from April 2005. The new act, which repeals and replaces the Human Tissue Act 1961, the (...) Anatomy Act 1984, and the Human Organ Transplants Act 1989, has its origins in events of serious public concern, namely the retained organs scandals at Bristol Royal Infirmary3 and the Royal Liverpool Childrens’ Hospital.4 The act is correspondingly dominated by regulation of postmortem examinations and retention of human tissue, with consistent emphasis on the need for fully informed consent. Compliance with these requirements is now mandatory with the threat of up to three years’ imprisonment and/or fines for any deviation.The impact of the original proposals within the bill on research and the clinical practice of pathology have been carefully considered and documented,5 with subsequent amendments to ameliorate professional concerns.6 The act, however, also carries significant implications for medical practice in areas where donor recruitment for transplantation can take place, and representations on these aspects during readings of the bill7 have produced neither clarification, justification, nor amendment within the final legislation.Section 43 will make it lawful for hospital authorities “to take steps for the purpose of preserving the part for use for transplantation and to retain the body for that purpose”. The original explanatory notes for the bill8 while it proceeded through parliament implied that such action, prior to consent to transplantation being sought, was then lawful, clause 44 as section 43 ….

Definition of the Problem: One of the main ethical arguments against the therapeutic transplantation of fetal tissue in severe cases of Parkinson’s disease is the allegation that the relationship between the abortion and the transplantation is a (bad)-means-to-a-(good)-end-relation.Arguments: This paper differentiates between the actual experimental single-case treatment and a potential mass treatment. In the former case, ethical guidelines seem to guarantee that abortion and transplantation are two distinct actions and therefore abortion is not a means to (...) the end transplantation on principle. However, in the latter case – the potential mass treatment of patients with more severe cases of Parkinson’s disease – there seem to be several technical, logistical and psychological reasons for the impossibility to distinguish between abortion and transplantation.Conclusion: Although abortion is not a means to the end transplantation as a matter of principle the ethical problems of a mass treatment would be immense.

Background: The family interview context is permeated by numerous ethical issues which may generate conflicts and impact on organ donation process. Objective: This study aims to analyze the family interview process with a focus on principlist bioethics. Method: This exploratory, descriptive study uses a qualitative approach. The speeches were collected using the following prompt: “Talk about the family interview for the donation of organs and tissues for transplantation, from the preparation for the interview to the decision of the family (...) to donate or not.” For the treatment of qualitative data, we chose the method of content analysis and categorical thematic analysis. Participants: The study involved 18 nurses who worked in three municipal organ procurement organizations in São Paulo, Brazil, and who conducted family interviews for organ donation. Ethical considerations: The data were collected after approval of the study by the Research Ethics Committee of the School of Nursing of the University of São Paulo. Results: The results were classified into four categories and three subcategories. The categories are the principles adopted by principlist bioethics. Discussion: The principles of autonomy, beneficence, non-maleficence, and justice permeate the family interview and reveal their importance in the organs and tissues donation process for transplantation. Conclusion: The analysis of family interviews for the donation of organs and tissues for transplantation with a focus on principlist bioethics indicates that the process involves many ethical considerations. The elucidation of these aspects contributes to the discussion, training, and improvement of professionals, whether nurses or not, who work in organ procurement organizations and can improve the curriculum of existing training programs for transplant coordinators who pursue ethics in donation and transplantation as their foundation.

Advances in transplantation have extended the life and relieved the suffering of thousands of individuals. The prospect of being able to use tissues from embryos, as well as from anencephalic newborns, offers the promise of further relief of suffering. However, these possibilities raise significant moral and public policy issues. The question arises of the extent to which those who disapprove of abortion may make use of tissues derived from abortion in order to treat serious diseases. This essay argues that, (...) with proper safeguards, such tissue can be used without cooperating in abortion. That is, even those who oppose abortion can benefit from the use of tissue procured during abortion. Questions also arise regarding the probity of maintaining a pregnancy in order to produce an anencephalic newborn whose biological existence will be maintained so as better to secure organs once death is declared. It is argued that, since no harm can be done to a being that has neither a sense of self or the capacity to feel pain, and since women have a right to forego abortions, there is no legitimate ground for opposing women's seeking meaning in their pregnancy through maximizing the opportunity of others to use the organs of their anencephalic newborn once death has been declared. Finally, it is argued that, since the capacities for sentience, a minimal condition for personhood, are never realized by an anencephalic, the entity has never been alive as a person. Therefore, there should be no opposition in principle to aborting anencephalics nor, after proper declaration, to making their organs available as one would after whole-brain death, despite the continued functioning of the brain stem.

Transplantation is becoming an increasingly more common approach to treatment of diseases of organ failure, making organ donation an important means of saving lives. Most world religions find organ donation for the purpose of transplantation to be acceptable, and some even encourage members to donate their organs as a gift of love to others.

These new approaches (...) should be discussed with bioethical considerations in mind, particularly the notion of human beings as a unity of body and spirit. (shrink)

The most publicly justifiable application of human cloning, if there is one at all, is to provide self-compatible cells or tissues for medical use, especially transplantation.

Indeed, it is not merely morally permissible but morally required that we employ cloning to produce embryos or fetuses for the sake (...) of providing cells, tissues or even organs for therapy, followed by abortion of the embryo or fetus.

Human uterus transplantation is currently under investigation as a treatment for uterine infertility. Without a uterus transplant, the options available to women with uterine infertility are adoption or surrogacy; only the latter has the potential for a genetically related child. UTx will offer recipients the chance of having their own pregnancy. This procedure occurs at the intersection of two ethically contentious areas: assisted reproductive technologies and organ transplantation. In relation to organ transplantation, UTx lies with composite (...) class='Hi'>tissue transplants such as face and limb grafts, and shares some of the ethical concerns raised by these non-life saving procedures. In relation to ART, UTx represents one more avenue by which a woman may seek to meet her reproductive goals, and as with other ART procedures, raises questions about the limits of reproductive autonomy. This paper explores the ethical issues raised by UTx with a focus on the potential gap between women's desires and aspirations about pregnancy and the likely functional outcomes of successful UTx.

Cognitive deficits were produced in rats by different methods of damaging the brain: chronic ingestion of alcohol, causing widespread damage to diffuse cholinergic and aminergic projection systems; lesions (by local injection of the excitotoxins, ibotenate, quisqualate, and AMPA) of the nuclei of origin of the forebrain cholinergic projection system (FCPS), which innervates the neocortex and hippocampal formation; transient cerebral ischaemia, producing focal damage especially in the CA1 pyramidal cells of the dorsal hippocampus; and lesions (by local injection of the neurotoxin, (...) colchicine) of the granule cells of the dentate gyrus. Following chronic alcohol or lesions of the FCPS, transplants of cholinergically rich fetal brain tissue into the terminal areas (neocortex and/or hippocampus) restored performance almost to control levels, with a time course consistent with growth of the transplants and integration with host tissue; transplants of cholinergically poor fetal tissue (hippocampus) were without effect, as were transplants of cholinergically rich tissue into the region containing the nuclei of origin of the FCPS. Grafts of primary cells enriched in glia and cultured neuroblastoma cells into the terminal areas of the FCPS were equally effective, suggesting that there are multiple mechanisms by which neural transplants can restore cognitive function following diffuse cholinergic damage. In contrast, after ischaemia- or neurotoxin-induced damage to CA1 or dentate granule cells respectively, cholinergically rich fetal transplants into the damaged hippocampal formation were ineffective in restoring performance. After ischaemic damage, however, performance was restored by suspension grafts of CA1 cells but not by transplants containing CA3 pyramidal cells or granule cells; and after colchicine damage it was restored by solid grafts containing granule but not CA1 pyramidal cells. Furthermore, electrophysiological evidence has demonstrated functional, graft type-specific host-graft functional neuronal connectivity. Thus, restoration of cognitive function by neural transplants is possible after damage to either diffuse (cholinergic) or point-to-point (intrahippocampal) forebrain systems, but the transplant must be appropriate to the damage to be repaired. Because the different types of brain damage studied provide analogues of human alcoholic dementia, Alzheimer's disease, and heart attack, these results are encouraging with regard to the eventual application of neural transplant surgery to the treatment of cognitive deficits in humans.

In lieu of an abstract, here is a brief excerpt of the content:Fetal Tissue ResearchMary Carrington Coutts (bio)I. IntroductionThe use of tissue from fetal remains for transplantation and biomedical research has become a controversial issue in recent years, involving scientists, doctors, patients, and the federal government. Fetal tissue is potentially useful in a wide range of treatments for a number of serious diseases, some of them affecting millions of people. Despite the promise, transplantation research using (...) fetal tissue from induced abortion slowed dramatically in the U.S. in 1988, when a moratorium was declared on federal funding for such research involving humans. That moratorium was lifted by President Clinton on January 21, 1993. Though the future of fetal tissue transplantation research is brighter, public debate on the issue is likely to continue, exacerbated by the "acrimonious abortion debate" (VI, Post 1991, p. 14).Using fetal tissue in biomedical research and in transplantation is not a new practice. As early as 1928 unsuccessful attempts were made to transplant fetal pancreas cells into diabetics (VII, Fichera 1928). Fetal tissue was used effectively in biomedical research during the 1950s, and was instrumental in the culture of the polio virus, which led to the development of the polio vaccine. Fetal tissue cultures were also essential in the development of the rubella vaccine, and continue to be used in virology research. Transplantation of fetal thymus cells into patients with DiGeorge Syndrome has been recognized as effective therapy since the late 1960s.Many of the therapeutic applications involving fetal tissue are still experimental, so it is difficult to pinpoint fetal tissue transplantation's therapeutic potential. One promising application is the transplantation of human fetal brain cells into the substantia nigra of patients with Parkinson's disease to restore motor function. Fetal neural transplants have also shown promise for patients suffering from Alzheimer's disease, spinal cord and other neural tissue injuries, and possibly some forms of cortical blindness. Fetal liver cells may be useful for treatment of some kinds of bone marrow disease seen in leukemia and aplastic anemia patients. [End Page 81] Fetal tissue transplantation may also help those suffering from blood clotting disorders, such as sickle cell anemia, thalassemia, and hemophilia. Fetal pancreatic tissue has potential applications in the treatment of diabetes, especially juvenile onset diabetes. Human gene therapy may also employ embryonic and early fetal cells.The Center for Biomedical Ethics at the University of Minnesota reports that more than 1,000 patients have received transplanted fetal tissue worldwide. Countries where fetal tissue transplantation has occurred include: Australia, Canada, China, the Commonwealth of Independent States (formerly the U.S.S.R.), Cuba, Czechoslovakia, Finland, France, Germany, Great Britain, Hungary, India, Italy, Mexico, Norway, Spain, Sweden, and Yugoslavia (IV, Vawter 1992, p. 2; I, Spain 1988; VII, Reinikainen 1989).Fetal tissue has unique characteristics that make it especially valuable in some treatments. Fetal cells develop much faster than adult cells, hastening the therapeutic effect—a potentially significant benefit for gravely ill patients. They are also less likely to be rejected by transplant recipients because they are less antigenic than adult cells. This reduces the need for the exact tissue matches that can be so difficult to obtain. Fetal tissue is also easier to culture and proliferates more readily than comparable adult tissue. Furthermore, fetal tissue is in greater supply, due to the number of elective abortions.Questions about the use of fetuses and fetal tissue in biomedical research were raised in the United States in the early 1970s. Between 1969 and 1973, all 50 states enacted the Uniform Anatomical Gift Act, allowing for the donation of all or part of the body of a dead fetus for research or therapeutic research. Prospects for the use of fetal tissue increased after the Supreme Court decision in Roe v. Wade legalized abortion. As the availability of fetal tissue increased so did the concern over the potential for controversial research on living, soon-to-be-aborted fetuses, and anxiety over maltreatment of dead abortuses. Vivid examples include Geoffrey Chamberlain's 1968 report of an experiment on a fetus of 26 weeks gestational age. Delivered by hysterotomy from a 14-year-old patient, the fetus was attached to an "artificial placenta" and kept alive for more than... (shrink)

Is there anything special about the ethical problems of intracerebral stem-cell transplantation and other forms of cell or tissue transplantation in the brain that provides neuroethics with a distinctive normative profile, setting it apart from other branches of medical ethics? This is examined with reference to some of the ethical problems associated with interventions in the brain such as potential changes in personal identity and potential changes in personality. It is argued that these problems are not sufficiently (...) specific to justify the autonomy of neuroethics as a separate discipline and can be handled by the established principles of medical ethics. The paper concludes with a constructive proposal how to deal with interventions in the brain for which the patient is unable to give valid ex-ante consent. (shrink)

More and more areas of medicine involve subjects donating tissues to another — blood, organs, bone marrow, sperm, ova and embryos can all be transferred from one person to another. Within the technical frameworks of biomedicine, such fragments are generally treated as detachable things, severed from social identity once they are removed from a particular body. However an abundant anthropological and sociological literature has found that, for donors and patients, human tissues are not impersonal. They retain some of the values (...) of personhood and identity, and their incorporation often has complex effects on embodied identity. This article draws on feminist philosophy of the body to think through the implications of some of these practices. Specifically, it draws on the idea of intercorporeality, wherein the body image is always the effect of embodied social relations. While this approach is highly productive for considering the stakes involved in tissue transfer, it is argued that the concept of body image has been too preoccupied with the register of the visual at the expense of introceptive data and health/illness events. Empirical data around organ transplant and sperm donation are used to demonstrate that the transfer of biological fragments involves a profound kind of intercorporeality, producing identifications and disidentifications between donors and recipients that play out simultaneously at the immunological, psychic and social levels.

In addition to the scientific and medical issues surrounding the use of fetal tissue transplants, the ethical implications should be considered. Two major ethical issues are relevant. The first of these is whether this experimental procedure can be justified on the basis of potential benefit to the patient. The second is whether the use of tissue obtained from intentionally aborted fetuses can be justified in the context of historical and existing guidelines for the protection of human subjects. The (...) separation of ethical decisions from medical practice and scientific research is necessary to prevent the exploitation of innocent human life. (shrink)

Transplantation of cerebral tissue is increasingly becoming an issue in today's ethical debate. This kind of transplantation has already been performed in the context of treating patients with Parkinson's disease. It ist also being considered in the handling of other serious diseases. The tissue for transplantation is obtained from aborted fetuses. Serious ethical problems are mainly arising out of the question of possible changes in the personalites of patients due to the transplanted cerebral tissue.

Transplantation research on samples and organs from deceased donors in England, Wales and Northern Ireland is under threat. The key problems relate to difficulties encountered in gaining consent for research projects, as distinct from consent to donation for clinical transplantation. They are due partly to the terms of the Human Tissue Act 2004 (the 2004 Act), and partly to its interpretation by the Human Tissue Authority (HTA). They include excessive interaction with donor representatives regarding ‘informed consent’ (...) to research projects, uncertainty as to the scope and duration of a donor's ‘authority’ over an organ, and restrictions caused by the apparent need for licensing of transplantation research under the 2004 Act, combined with lack of certainty, or guidance, as to the distinction between ‘research’, which requires a licence, and ‘service development’, which does not. In our view this confusion hinders and deters Specialist Nurses for Organ Donation in approaching donor representatives and discussing possible research projects with them. It has also, as we have reported elsewhere, led to abandonment of research projects for fear of liability, despite both Research Ethics Committee (REC) approval and donor consent. Such problems do not seem to occur under the transplant laws of most other comparable jurisdictions. The Transplantation Ethics Symposium, ‘The ethics of organ retrieval: goals, rights and responsibilities’, hosted by the MRC Centre for Transplantation at King's College London in December 2010, revealed that many senior clinicians and researchers, administrators, and lawyers are both unclear and in disagreement concerning the effects of the 2004 Act and the extent to which it is adhered to or ignored in practice. In this paper we examine the difficulties encountered and suggest solutions based on a less restrictive interpretation of the 2004 Act, or, more probably, a regulatory change under its authority. We propose that, in the long term, a law which includes consent for REC-approved research within the general consent for organ donation and transplantation seems preferable to the present system, both ethically and in practical terms.

The principal focus of this paper is to consider the implications of head and neck transplantation surgery on the issue of personal identity. To this end, it is noted that the immune system has not only been established to impose a level of self-identity on bodily cells, it has also been implicated in mental development and the regulation of mental state. In this it serves as a paradigm for the mind as the product of cephalic and extracephalic systems. The (...) importance of bodily systems in identity is then discussed in relation to phantom tissue syndrome. The data strongly indicate that, even if surgically successful, head and neck transplantation will result in the loss of the continuity of personal identity. (shrink)

Splitting livers allows two people (usually an adult and a child) to receive a liver transplant from one donated adult liver, but the risks to the adult recipient are greater than if they had received the equivalent whole liver. It has been suggested, therefore, that splitting livers harms adult recipients. Without liver splitting, however, there would be few livers available for children, and paediatric waiting time and waiting list mortality would significantly increase. In this paper, we argue that although splitting (...) livers makes adults worse off, this should be considered sub-optimal benefit rather than harm. We explore justifications for sub-optimally benefitting adults in this way and consider alternatives to the current approach. We argue that splitting livers masks the more fundamental problem of low paediatric donation rates and that increasing the number of paediatric donations would improve the situation for both adult and paediatric liver patients.

It is often presumed that effects of neural tissue transplants are due to release of neurotransmitter. In many cases, however, effects attributed to transplants may be related to phenomena such as trophic effects mediated by glial cells or even tissue reactions to injury. Any conclusion regarding causation of graft effects must be based on the control groups or other comparisons used. In human clinical studies, for example, comparing the same subject before and after transplantation allows for many (...) interpretations of the causes of clinical changes. (shrink)

Originally published in 1990, this study of the moral problems bound up with transplant therapy addresses a finely balanced distinction between ethical issues relating to its experimental nature on the one hand and those which arise when transplantation is routine on the other. Among the issues examined are proposals for routine cadaveric harvesting, criteria for organ and tissue procurement from living donors, foetuses, non-human animals and current ethical problems with artificial implants. Written as a contribution to practical philosophy, (...) this book will interest ethicists and health care professionals. (shrink)

Ovarian tissue transplantation is an experimental procedure that can be used to treat both infertility and premature menopause. Working within the current legal framework in the USA, I examine whether ovarian tissue should be legally treated like gametes or organs in the case of ovarian tissue transplantation between two women. One option is to base classification upon its intended use: ovarian tissue used to treat infertility would be classified like gametes, and ovarian tissue (...) used to treat premature menopause would be classified like organs. In the end, however, I argue that this approach will not work because it engenders too many legal, cultural and logistical concerns and that, at least for the near future, we should treat ovarian tissue like gametes.
