The article analyses practices, perceptions and political dramatizations of bone marrow donation in Cyprus. Based on empirical data from an ethnographic study on practices of organ and bone marrow transplantation in postcolonial Cyprus, forms of oppositional biopolitics are analysed that are not bound by the modern, étatist regime of governing populations but capitalize on new developments in biomedicine, on new political movements, as well as on transformations in the political sphere. These reconfigurations are interpreted as (...) instances of an emerging bio-subpolitics that transcends national borders and produces new complexities, interrelations, associations and social forms that come into being alongside biomedicine. At the same time, these developments co-produce cosmopolitan citizens and new subjectivities, transcending nationally bound regimes of political deliberation and identification. These forms of biopolitics mobilize local historical experiences and take advantage of affordances provided by biomedical platforms operating on a global scale that make available an opportunity structure for a cosmopolitan bio-subpolitics.

Haematopoietic stem cell transplantation is a treatment modality that saves the health and lives of a growing number of patients around the world. In the majority of cases, the procedure is conducted to treat haematologic neoplasms, although it can also be used as a therapy for some non-haematooncological diseases. The progress that has been taking place in the field of haematopoietic stem cell transplantation involves the need for recruiting more and more potential unrelated bone marrow donors for allotransplantation. (...) In Poland, the number of people registering as potential bone marrow donors has been continuously growing and in order to maintain this trend, it is necessary, above all, to consistently spread the noble idea of bone marrow donation and to raise Poles’ awareness and knowledge about haematopoietic stem cell transplantation. Unfortunately, the situation caused by the severe acute respiratory syndrome coronavirus 2 pandemic limited the opportunities to act in public space and, as a consequence, it has become more difficult to achieve the objectives associated with recruiting new potential donors. The article provides a presentation of ethical and practical aspects associated with bone marrow donations as well as an overview of the legal situation concerning bone marrow donating and transplantation in Poland. The purpose of the paper is to also present some of the changes in transplantation procedures that have emerged as a consequence of the current epidemiological situation. The authors would like to emphasize the importance and the rightfulness of taking action that enables further development of transplantology. (shrink)

The only hope of survival for children with a number of life-threatening illnesses is a successful bone marrow transplant (BMT). Unlike the treatment source for most therapies, the raw material for transplant therapy comes from a human being. Although, many BMTs are autologous, utilizing the patient's own bone marrow, a large percentage of childhood BMTs rely on bone marrow from children or adolescents who are biological siblings to the sick child. Medical and legal systems (...) are confronted with a dilemma when healthy children are needed to undergo minimally risky, yet somewhat painful, procedures for the benefit of their critically ill siblings. This article reviews legal issues involved in sibling bone marrow donation and psychological research that is relevant to those issues. The article concludes with proposed directions for future psycholegal research and a discussion of ethical issues that are not amenable to empirical investigation. (shrink)

The child was 2 years, 8 months old and weighed 25 pounds, one-fifth the weight of her mother, for whom she was to be the bone marrow donor. The mother had suffered a relapse of acute myelogenous leukemia; her physicians recommended a bone marrow transplant. The child was the closest human leukocyte antigen match and thus the best donor candidate for her mother's transplant.

The stipulation of living organ transplantation policy and practice in Bangladesh is family-oriented, with relatives being the only people legally eligible to donate organs. There have been very few transplantations of bone marrows, liver lobes, and kidneys from related-living donors in Bangladesh. The major question addressed in this study is why Bangladesh is not getting adequate organs for transplantation. In this study, I examin the stipulations of the policy and practice of living organ donation through the lens of (...) 32 key stakeholders including physicians and nurses, a health administrator, organ donors and recipients, and their family members, as they can shed light on the realities and problems of organ donation for transplantation in Bangladesh. My ethnography reveals that the family members are always encouraged to donate organs for transplantation, and saving the lives of relatives through organ donation is seen as a moral obligation. Many view saving the life of a relative by donating one’s organs as equivalent to saving one’s own life. An assessment of the dynamics of biomedicine, religion, and culture leads to the conclusion that the family-oriented organ donation policy and practice have been widely endorsed and accepted in Bangladesh, and Islamic ethical principles and collective family ethos undergird that policy and practice. However, the unavailability of medical resources, lack of post-operative coverage for organ donors, religious misconceptions and unawareness of the general public, and the absence of posthumously donated vital organs for transplantation are perceived to be the most common barriers to a successful living donor-recipient pair organ transplantation. By overcoming these obstacles, Bangladesh can develop a successful living donor-recipient pair organ transplantation program that will ensure improved healthcare outcomes, promote altruism and solidarity among Bangladeshi families, and protect the poor from having their organs sold to wealthy patients.

Parents are usually appreciated as possessing legitimate moral authority to compel children to make at least modest sacrifices in the service of widely shared values of moral decency. This essay argues that such authority justifies allowing parents to authorize a child to serve as an organ or tissue donor in certain circumstances, such as to authorize bone marrow donations to save a sibling with whom the potential donor shares a deep emotional bond. The approach explored here suggests, however, (...) that at least under some conditions, parents have legitimate authority to authorize donations forbidden by current guidelines. (shrink)

Various cell types cooperate to create a highly organized and dynamic micro-environmental niche in the bone marrow. Over the past several years, the field has increasingly recognized the critical roles of the interplay between bone marrow environment and hematopoietic cells in normal and deranged hematopoiesis. These advances rely on several new technologies that have allowed us to characterize the identity and roles of these niches in great detail. Here, we review the progress of the last several (...) years, list some of the outstanding questions in the field and propose ways to target the diseased environment to better treat hematologic diseases. Understanding the extrinsic regulation by the niche will help boost hematopoiesis for regenerative medicine. Based on natural development of hematologic malignancies, we propose that combinatory targeting the niche and hematopoietic intrinsic mechanisms in early stages of hematopoietic malignancies may help eliminate minimal residual disease and have the highest efficacy. The bone marrow is the home for blood-forming hematopoietic stem and progenitor cells. Normal generation of blood and immune cells depends on highly regulated interactions between these stem and progenitor cells with their surrounding environment. Emerging evidence suggests that therapeutic interventions directed at these cellular interdependencies can help boost hematopoiesis and eradicate malignant hematopoietic cells. (shrink)

Many inherited metabolic diseases may lead to varying degrees of brain damage and thus also to intellectual disability. Bone marrow transplantation (BMT) has been used for over two decades as a form of secondary prevention to stop or reverse the progress of the disease process in some of these conditions. At the population level the impact of BMT on the prevalence of intellectual disability is minute, but at the individual level its impact on the prognosis of the disease (...) and the well-being of the patient can be substantial. The dark side of BMT use is the burden of side effects, complications and transplantation-related mortality in less successful cases. The ethical issues involved in this therapy are discussed in this review. (shrink)

South Africa, like many other countries that have suffered through the brutality of colonisation and later apartheid, continues to grapple with ways of healing the scars that remain visible in its citizens’ bodies and psyches. These scars are both literal and figurative, and the impact thereof is felt daily, as people try to find ways of navigating the now-‘democratised’ and ‘liberated’ country. There is a persistent restlessness, as structural violence continues to affect members of society – especially those on the (...) margins, struggling for survival each day. In her book, Reweaving the Soul of the Nation, Mmatshilo Motsei offers insights into ways of imagining the possibilities of reweaving people’s broken souls. Using Motsei’s reflections as a compass, this article offers insights into the challenges of colonialism and spirituality, and interrogates the complexities of what education means. The article concludes by proposing ways of moving towards the possibility of healing our wounded souls. Contribution: This contribution forms part of the ‘VukaniBantuTsohangBatho collection on the Spirituality of Black Liberation’ and aims at honoring and celebrating the life and scholarly contributions of Vuyani Vellem. This article responds to the call by highlighting the role of spirituality in the reimagining of African lives and experiences. (shrink)

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)

Healthcare decision making for children has adopted the best interest of the child standard, a principle originally employed by judges to adjudicate child placement in the case of parental death, divorce, or incompetence. Philosophers and medical ethicists have argued whether the best interest principle is a guidance principle (informing parents on how they should make healthcare decisions for their child), an intervention principle (deciding the limits of parental autonomy in healthcare decision making), or both. Those who defend it as only (...) a guidance principle often cite the harm principle as the appropriate intervention principle. In this article, I challenge current use of the best interest principle in pediatric decision making as a guidance principle and as an intervention principle. I propose a model that I call constrained parental autonomy, which focuses on promoting and protecting the child’s primary goods or basic needs. I show that constrained parental autonomy can serve as both a guidance principle and an intervention principle in making decisions. I conclude by examining a case study involving bone marrow donation by a young child to her sister. (shrink)

The influence of physician judgment on the disclosure, competency, understanding, voluntariness, and decision aspects of informed consent for bone marrow transplantation are described. Ethical conflicts which arise from the amount and complexity of the information to be disclosed and from the barriers of limited time, patient anxiety and lack of prior relationship between patient and physician are discussed. The role of the referring physician in the decision-making is considered. Special ethical issues which arise with use of healthy related (...) bone marrow donors are discussed, as is the physician's discretion in raising questions of competency. It is concluded that in this setting, regardless of the theoretical goals of the physician, patients appear to utilize informed consent discussions to assess their capacity to trust the physician rather than as a time to weigh the large amount of relevant data. The conscientious physician best serves the patient with recommendation of the best medical alternative rather than with attempts to remain neutral. (shrink)

The theoretical rationale was the author’s Functional Model of Health, where health is construed as a function of creative coping with stress. Participants in the study were 141 patients with blood cancer treated with bone marrow transplantation at the Hematology Clinic, Jagiellonian University Collegium Medicum. Besides a standardized interview the following instruments were used: STAI by Spielberger, CISS and CHIP by Endler and Parker, and SOC-29 by Antonovsky. Health status was operationalized using 10-point self-rating scales to assess the (...) patients’ perceived health and sense of calmness, while their objective health was rated by a medical expert - hematologist. In the statistical analyses significant correlations were found between stress level and the patients’ subjective health. The following variables predicted stress intensity: anxious personality, distraction coping strategy, female sex, and sense of meaningfulness. Subjective health predictors of leukemia patients are: objective health, level of stress, by the patient’s sense of meaningfulness and focusing on negative emotions. To promote patients’ health moreover, their sense of meaningfulness in life and in being active should be supported and enhanced. (shrink)

The UK Human Fertilisation and Embryology Authority was right to permit tissue typing preimplantation genetic diagnosisOn July 21 2004, the Human Fertilisation and Embryology Authority , Britain’s regulatory agency for reproductive technologies, revised its policy on preimplantation genetic diagnosis for tissue typing.1,2 The authority of the HFEA to enact such a policy was affirmed by the UK’s highest court, the House of Lords, on April 28 2005.3 Preimplantation genetic diagnosis combines in vitro fertilisation with genetic testing. In PGD, embryos generally (...) undergo biopsy prior to the eight cell stage, followed by genetic testing for a particular trait. Tissue typing PGD is done to identify an embryo that is tissue matched for a child suffering from a severe disease requiring bone marrow or cord blood stem cell transplantation and for whom no living donor exists. This procedure was first performed in 2000.4 Precise matching of tissue types is critical to successful tissue transplant, and the donors of such tissues are often referred to as “saviour siblings”.Where a tissue matched individual already exists, extracting bone marrow from that individual or collecting cord blood already in storage, rather than creating a match, presents the most immediate treatment alternative. Bone marrow donation from adults or other medically competent individuals is not generally ethically contested, and bone marrow donation from medically incompetent individuals is also permissible under certain conditions.5 Where no living tissue donor exists, however, intentionally creating a donor through tissue typing PGD is among a short list of possible treatment options.The July HFEA policy change makes PGD licensable in cases where tissue typing is the only purpose of testing. Previously, PGD was licensable in the UK only for disease testing, and tissue typing PGD was permissible only when …. (shrink)

This clinical case report illustrates the potential dilemmas that can arise from knowledge gained through genetic analysis. These conflicts require careful ethical analysis of presumed duties to protect patient privacy and maintain confidentiality, the duty to warn a second party of a health risk, and the duty of veracity. While the questions raised by genetic testing of one individual for disease that reveals potentially important information about relatives, such as risk for Huntington chorea or breast cancer, have been discussed, the (...) continuing expansion in our capacity for sophisticated genetic analysis continues to present new and challenging situations. The resolution of this case and others like it requires close collaboration among the treatment team, geneticists, and clinical ethicists. (shrink)

Since the birth of the first test-tube baby, Louise Brown, in 1977, we have seen truly remarkable advances in biotechnology. We can now screen the fetus for Down Syndrome, Spina Bifida, and a wide range of genetic disorders. We can rearrange genes in DNA chains and redirect the evolution of species. We can record an individual's genetic fingerprint. And we can potentially insert genes into human DNA that will produce physical warning signs of cancer, allowing early detection. In fact, biotechnology (...) has progressed to such a point that virtually any kind of genetic manipulation, if not already possible, is just around the corner. But these breakthroughs also raise serious ethical and moral dilemmas that we are only now beginning to confront. In Wonderwoman and Superman, noted medical ethicist John Harris offers the first thorough analysis of the moral dilemmas created by the revolution in molecular biology. Covering a wide array of recent innovations, Harris discusses, for example, the moral decisions involved and the consequences of creating egg and embryo banks. Who should be allowed to use such resources? Should recipients be screened? Should such banks be open for public or private use? And does it cheapen life to make embryos available for sale? In another chapter, Harris examines the question of conceiving children chiefly for organ donation, focusing on the recent case of a woman who wanted to have a second child to provide a bone marrow donor for her first child sick with leukemia (she intended to abort the fetus if its bone marrow did not genetically match that of her living child). In this case, the medical staff had to decide whether they should perform in-vitro fertilization, knowing that the mother did not satisfy the clinic's criteria (there was no father), and also knowing the potential for abortion. Discussing the ethics of the mother's choice and the clinic's choice, Harris asks whether it is morally correct to create a child as an organ donor, whether the future child would suffer, whether it is worth any suffering to be born, and who has the right to weigh the various factors (both moral and physiological) involved in making these decisions. Delving into a multitude of issues such as when life begins, when suffering is needless, and whether we should play God, Wonderwoman and Superman provides not only a thought-provoking inquiry into the potential and actual ethical dilemmas created by the many advances in biotechnology, but challenges us to learn to choose responsibly and to face the moral implications of the choices that confront us.

Organ transplantation from living related donors in Bangladesh first began in October 1982, and became commonplace in 1988. Cornea transplantation from posthumous donors began in 1984 and living related liver and bone marrow donor transplantation began in 2010 and 2014 respectively. The Human Organ Transplantation Act officially came into effect in Bangladesh on 13th April 1999, allowing organ donation from both brain-dead and related living donors for transplantation. Before the legislation, religious leaders issued fatwa, or religious rulings, (...) in favor of organ transplantation. The Act was amended by the Parliament on 8th January, 2018 with the changes coming into effect shortly afterwards on 28th January. However, aside from a few posthumous corneal donations, transplantation of vital organs, such as the kidney, liver, heart, pancreas, and other body parts or organs from deceased donors, has remained absent in Bangladesh. The major question addressed in this article is why the transplantation of vital organs from deceased donors is absent in Bangladesh. In addition to the collection of secondary documents, interviews were conducted with senior transplant physicians, patients and their relatives, and the public, to learn about posthumous organ donation for transplantation. Interviews were also conducted with a medical student and two grief counselors to understand the process of counseling the families and obtaining consent to obtain posthumous cornea donations from brain-dead patients. An interview was conducted with a professional anatomist to understand the processes behind body donation for the purposes of medical study and research. Their narrative reveals that transplant physicians may be reticent to declare brain death as the stipulations of the 1999 act were unclear and vague. This study finds that Bangladeshis have strong family ties and experience anxiety around permitting separating body parts of dead relatives for organ donation for transplantation, or donating the dead body for medical study and research purposes. Posthumous organ donation for transplantation is commonly viewed as a wrong deed from a religious point of view. Religious scholars who have been consulted by the government have approved posthumous organ donation for transplantation on the grounds of necessity to save lives even though violating the human body is generally forbidden in Islam. An assessment of the dynamics of biomedicine, religion and culture leads to the conclusion that barriers to posthumous organ donation for transplantation that are perceived to be religious may actually stem from cultural attitudes. The interplay of faith, belief, religion, social norms, rituals and wider cultural attitudes with biomedicine and posthumous organ donation and transplantation is very complex. Although overcoming the barriers to organ donation for transplantation is challenging, initiation of transplantation of vital organs from deceased donors is necessary within Bangladesh. This will ensure improved healthcare outcomes, prevent poor people from being coerced into selling their organs to rich recipients, and protect the solidarity and progeny of Bangladeshi families.

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 Nepal, live donor organ transplantation is only 14 years old with the first successful kidney transplant made in 2008 and a successful liver and bone marrow transplant made in 2016. However, transplantation of cadaveric cornea dates back to 1998. There are still no cases of animal-to-human organ transplantation in Nepal. There are stringent laws to regulate human body organ transplantation in Nepal which are amended from time to time. However, there is a racket of human traffickers who (...) lure rural people from this low-income country into the illegal organ trade. Furthermore, there is a substantial lack of awareness of organ donation among the general public. This article focuses on the stipulations of ethical, legal, and practical issues of obtaining organs procured from living and brain-dead donors that support the process of transplantation in Nepal. In addition, the article also explores the legal and practical issues of organ trafficking and organ donation awareness in Nepal on the basis of factual data and findings from other studies.

In 1999, a case was described on national television in which a woman had enlisted onto an international bone marrow registry with the altruistic desire to offer her bone marrow to some unidentified individual in need of a transplant. The potential donor then was notified that she was a compatible match with someone dying from leukemia and gladly donated her marrow, which cured the recipient of the disease. Years later, though, the recipient developed end-stage renal (...) disease, a consequence of the high-dose chemotherapy she received earlier to destroy her stem cells and prepare her for the bone marrow transplant. Finding a suitable donor for a kidney transplant proved extremely difficult. Desperate, she requested that the donor registry personnel help her locate the individual who earlier was determined to be a compatible donor and asked this now-identifiable individual to consider donating one of her two normally functioning kidneys for a kidney transplant.

This paper presents an overview of the dimensions of unsafe motherhood, contrasting data from economically developed countries with some from developing countries. It addresses many common factors that shape unsafe motherhood, identifying medical, health system and societal causes, including women's powerlessness over their reproductive lives in particular as a feature of their dependent status in general. Drawing on perceptions of Jonathan Mann, it focuses on public health dimensions of maternity risks, and equates the role of bioethics in conscientious medical care (...) to that of human rights in public health care. The microethics of medical care translate into the macroethics of public health, but the transition compels some compromise of personal autonomy, a key feature of Western bioethics, in favour of societal analysis. Religiously‐based morality is seen to have shaped laws that contribute to unsafe motherhood. Now reformed in former colonizing countries of Europe, many such laws remain in effect in countries that emerged from colonial domination. UN conferences have defined the concept of ‘reproductive health’ as one that supports women's reproductive self‐determination, but restrictive abortion laws and practices epitomize the unjust constraints to which many women remain subject, resulting in their unsafe motherhood. Pregnant women can be legally compelled to give the resources of their bodies to the support of others, while fathers are not legally compellable to provide, for instance, bone‐marrow or blood donations for their children's survival. Women's unjust legal, political, economic and social powerlessness explains much unsafe motherhood and maternal mortality and morbidity. (shrink)

I would have preferred that the Special Section on Children as Organ Donors had focused on the donation of a specific organ because morally relevant differences are obscured when the subject is discussed in general terms. The donation of a lobe of liver and peripheral blood or bone marrow stem cells does not result in the permanent loss of vital tissue because these organs regenerate; however, a kidney does not regenerate and its donor loses a vital (...) organ permanently. Liver tissue and peripheral blood or bone marrow stem cells are typically required to save a life, but, because most patients with end-stage renal disease can be kept alive on dialysis, the donation of a kidney is rarely life saving. Also, donor risk is organ specific; for example, it is more dangerous to donate a lobe of liver than it is to donate peripheral blood or bone marrow stem cells. (shrink)

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)

At the end of 1999 the Danish Council of Ethics published a report on organ and tissue donation from living donors. The report focused on kidney and bone marrow transplantations, as these are presently the most common transplantations from live donors. During the work on the report, it became clear to the Council that, apart from problems concerning coercion and commercialization that affected both adult and child donors, by far the largest ethical problems occurred in donations from (...) children.

When I started doing clinical ethics rounds, in the mid 1980s, I decided to venture onto the pediatrics ward. The first patient I encountered was a 3-year-old girl returning to her room, groggy from general anesthesia. When I inquired about her, the nurse explained that she had just gone through the procedure to donate bone marrow for her 1-year-old sister, who was preparing to undergo bone marrow transplantation for leukemia.

Hematopoietic stem cell transplantation is a widely accepted practice in the United Kingdom (UK). The relatively liberal UK law permits donation both within families and from strangers, and even allows the creation of “saviour siblings” who are brought into being with the specific intent of having them donate stem cells to save other members of their family. This chapter describes the regulation of HSCT in the UK and highlights some ethical issues related to discrimination against some categories of potential (...) donors, the accuracy of the information provided to potential donors, and the controversy concerning saviour siblings.

An emerging concept is that quiescent mature skeletal cells provide an important cellular source for bone regeneration. It has long been considered that a small number of resident skeletal stem cells are solely responsible for the remarkable regenerative capacity of adult bones. However, recent in vivo lineage‐tracing studies suggest that all stages of skeletal lineage cells, including dormant pre‐adipocyte‐like stromal cells in the marrow, osteoblast precursor cells on the bone surface and other stem and progenitor cells, are (...) concomitantly recruited to the injury site and collectively participate in regeneration of the damaged skeletal structure. Lineage plasticity appears to play an important role in this process, by which mature skeletal cells can transform their identities into skeletal stem cell‐like cells in response to injury. These highly malleable, long‐living mature skeletal cells, readily available throughout postnatal life, might represent an ideal cellular resource that can be exploited for regenerative medicine.

This article draws on a five-year, multi-sited transnational research project on the global traffic in human organs, tissues, and body parts from the living as well as from the dead as a misrecognized form of human sacrifice. Capitalist expansion and the spread of advanced medical and surgical techniques and developments in biotechnology have incited new tastes and traffic in the skin, bones, blood, organs, tissues, marrow and reproductive and genetic marginalized other. Examples drawn from recent ethnographic research in Israel, (...) the Palestinian Authority and Turkey serve to cast light on the dark side of organs harvesting and transplantation. The article focuses on the dangers of the `fetishized kidney' for both sellers and buyers, for whom this new commodity has become an organ of opportunity and an organ of last resort. The bodily sacrifice is disguised as a donation, rendered invisible by its anonymity, and hidden under the medical rhetoric of `life saving' and `gift giving'. It suggests that the ultimate fetish as recognized long ago by Ivan Illich is the idea of `life' as object of manipulation. (shrink)

Two recent publications highlight the role of bone‐forming cells, the osteoblasts, in controlling the development of neighboring haematopoietic stem cells (HSCs).1,2 Using two distinct transgenic mouse models, one using the conditional deletion of the Bone Morphogenetic Protein Receptor 1A (BMPR1A) gene, the other using over‐expression of an active PTH/PTHrP receptor (PPR) mutant within osteoblasts, the authors show parallel, concordant increases in the generation of trabecular osteoblasts and the number of HSCs. In situ staining showed that rarely cycling HSCs (...) sporadically attach to endosteal osteoblasts, while in vitro assays indicated that ligation of Jag1 on osteoblasts by Notch1 on HSCs promotes HSC proliferation. These two independent works have revived and revitalized the notion that osteoblasts are a major, defining component of the HSC niche within the bone marrow (BM). This minireview discusses these results in the context of other recent studies of mesenchymal cells within the BM microenvironment, presents one potential unified model of the functional anatomy of the BM HSC niche, and highlights new questions raised by these and other studies of osteoblasts and HSCs.

Endosteal stem cells are a subclass of bone marrow skeletal stem cell populations that are particularly important for rapid bone formation occurring in growth and regeneration. These stem cells are strategically located near the bone surface in a specialized microenvironment of the endosteal niche. These stem cells are abundant in young stages but eventually depleted and replaced by other stem cell types residing in a non‐endosteal perisinusoidal niche. Single‐cell molecular profiling and in vivo cell lineage analyses (...) play key roles in discovering endosteal stem cells. Importantly, endosteal stem cells can transform into bone tumor‐making cells when deleterious mutations occur in tumor suppressor genes. The emerging hypothesis is that osteoblast‐chondrocyte transitional identities confer a special subset of endosteal stromal cells with stem cell‐like properties, which may make them susceptible for tumorigenic transformation. Endosteal stem cells are likely to represent an important therapeutic target of bone diseases caused by aberrant bone formation. (shrink)

Development of gene transfer systems provides a key tool for understanding gene function. Exciting and often unexpected consequences from embryo manipulations are yielding insights into molecular mechanisms underlying development under normal and pathogenic states, and are providing animal models for diseases. Contributing to this progress is the elegant work on c‐fos(1), where Wagner and coworkers identify this proto‐oncogene as a primary factor which directs cell differentiation along the osteoclast/macrophage lineages, and thus regulates bone remodeling. Their studies support a link (...) between skeletogenesis, marrow formation and hematopoiesis, and may help to delineate mechanisms underlying the oncogenic transformation of skeletal and hematopoietic cells.

Endochondral bone formation can take place in the embryo, during fracture healing, or in postnatal animals after induction by implanted demineralized bone matrix. This matrix‐induced bone formation recapitulates the embryonic sequence of bone formation morphologically and biochemically. The steps in bone formation in both systems include differentiation of cartilage from mesenchyme, cartilage maturation, invasion of the cartilage by blood vessels and marrow precursors, and formation of bone and bone marrow. Recently, (...) class='Hi'>bone inductive molecules from demineralized bone matrix have been purified, sequenced and produced as recombinant proteins. While there are similarities between bone development in the embryo and that after induction by these purified molecules, the molecules responsible for bone induction in the embryo have not yet been defined. Because of similarities between the two methods of bone formation, studies of Bone induction by demineralized bone matrix may help to elucidate mechanisms of embryonic bone induction. (shrink)

Cadaveric donation comprises organ donation—that is, taking organs from brain dead people, as well as tissue donation, meaning taking tissues from brain dead as well as heart dead people. The organ transplant procedure from brain dead patients is beyond the scope of the pathologist, as it is done by surgeons in the operating theatre. In a broader sense, however, pathologists are involved in cadaveric tissue donation as well as taking tissues from cadavers for diagnostic procedures within (...) the framework of the autopsy , and to gather material for research and training students and pathology residents . For cadaveric tissue donation, different ethical and practical issues must be considered, which we will try to review in this paper from the perspective of the pathologist.CADAVERIC TISSUE SAMPLING FOR TRANSPLANTATION PURPOSESSeveral tissues can be taken from “true” cadavers that may still be used for transplantation such as skin, corneas, tendons, bone. This is usually done in collaboration with the pathologist, who is in most countries responsible for the body after the death of the patient in the hospital. All these tissues can be harvested several hours after death, as they undergo only slow degradation. In The Netherlands, as dictated by law, patients must actively have given permission for donation during life by registering with the Transplantation Register. Since this procedure was implemented, the number of organs available for donation has not increased but decreased somewhat, while the number of tissues has increased. A great obstacle to the increase in the number of donations is that only 37% of the population is registered …. (shrink)

No one has the right to say what should be done to their body after deathIn my opinion any concept of property in the human body either during life or after death is biologically inaccurate and morally wrong. The body should be regarded as on loan to the individual from the biomass, to which the cadaver will inevitably return. Development of immunosuppressive drugs has resulted in the cadaver becoming a unique and invaluable resource to those who will benefit from organ (...) donation. Faced with the biological reality, the moral error of any concept of property in the body, and the quantitative failure of voluntary organ donation, I believe that the right of control over the cadaver should be vested in the state as representative of those who may benefit from organ donation.How one regards the dead human body, the cadaver, is in part governed by one’s familiarity with it. At the present time, very few people ever see a cadaver which has not in some way been altered after death, and even fewer touch, handle, deal in any way with the dead human body. In developed countries, death itself most frequently occurs away from the home, in an institution, under the supervision of professional caregivers. For most people, ideas concerning the cadaver, its nature, the proper way to deal with it, are formed under these conditions.As a pathologist specialising in forensic pathology, for 50 years I have been at the other end of the spectrum of experience. In my daily work I have been privileged to examine the cadaver in all its stages after death from the immediate postmortem moments through all the stages of decomposition to bare bones. Working in a relatively small community, I have sometimes been charged with examining the body of someone I …. (shrink)

The behavior of somatic stem cells is regulated by their niche. Interaction between hematopoietic stem cells (HSCs) and their niches are a representative model to understand stem cell‐niche interplay. Here, we provide an overview of crosstalk between HSCs and their niches in bone marrow and extramedullary organs following the life journey of HSCs from emergence, development, maturation until aging. We highlight the unique differences of HSC niches in different life stages within various organs focusing on recent literature to (...) propose new speculations and hypotheses. (shrink)
