Fascination with In re Quinlan, the first high-profile right-to-die case in the United States, led the author to law school. By the time she received her law degree, bioethics was emerging as a field of study, and law and bioethics became her field. The mission of legal education is to teach students to "think like a lawyer," which can be a productive way to approach issues in many fields, including bioethics. Legal education can also teach individuals to respect people whose views on bioethics issues differ from their own...

Hematopoietic stem cell transplantation (HSCT) is one of a range of therapeutic options available to patients suffering from various diseases. HSCT procedure involves important ethical and legal aspects that can occur at every phase of the procedure: the clinical choice of whether to perform the procedure, pretransplantation preparation regimens, donor selection, stem cell harvest procedure, transplantation phase, and short-term and long-term follow-up care. In this discussion paper, we outline the ethical issue-facing physicians involved in HSCT...

At every moment, somewhere in the world, a group of men and women are sitting around a table deliberating about an ethical issue posed by medicine and research, whether as a research ethics committee; a hospital or clinical ethics committee; a stem-cell review committee; a gene transfer research committee; a biobank ethics committee; an ethics advisory committee for a medical or nursing association or nongovernmental organization; a state, provincial, national, or intergovernmental bioethics committee; or an ad hoc panel examining a particular development or case...

Recently, attention has been drawn to the basic principles governing the use of human embryos in research: specifically, the so-called fourteen-day rule. This rule stipulates that human embryos should not be allowed to grow in vitro past fourteen days of development. For years, the fourteen-day limit was largely theoretical, since culture techniques were not sufficient to maintain embryos up to this point. Yet in the past year, research has suggested that growing embryos beyond fourteen days might be feasible and scientifically valuable...

The "14-day rule" for embryo research stipulates that experiments with intact human embryos must not allow them to develop beyond 14 days or the appearance of the primitive streak. However, recent experiments showing that suitably cultured human pluripotent stem cells can self-organize and recapitulate embryonic features have highlighted difficulties with the 14-day rule and led to calls for its reassessment. Here we argue that these and related experiments raise more foundational issues that cannot be fixed by adjusting the 14-day rule, because the framework underlying the rule cannot adequately describe the ways by which synthetic human entities with embryo-like features (SHEEFs) might develop morally concerning features through altered forms of development...

Conducting research on the stem cell lines might bring some worthy good to public. Human Stem Cells (hSCs) research has provided opportunities for scientific progresses and new therapies, but some complex ethical matters should be noticed to ensure that stem cell research is carried out in an ethically appropriate manner. The aim of this review article is to discuss the importance of stem cell research, code of ethics for stem cell research in Iran and ethical recommendation. Generation of stem cells for research from human embryo or adult stem cells, saving, maintenance and using of them are the main ethical, legal and jurisprudence concerns in Iran...

Carlo Petrini
The clinical applications of stem cells pose a multitude of problems, including safety, efficacy, information and consent, the right to unproven treatments, the "right to try", costs, access, sustainability, scientific scrupulousness, patents and regulatory aspects, to name but a few. This article does not address individual issues, but rather introduces and discusses some of the possible approaches to solving the problems. The first part compares the consequentialist and deontological approaches, offering an overview of "top-down" and "bottom-up" models and proposing the principles of personalism as applied in clinical settings...

Hematopoietic stem cell transplantation (HSCT) is an important treatment option for children with severe and refractory sickle cell disease (SCD) with debilitating clinical complications. HSCT with cells from the bone marrow of a HLA-identical sibling used in SCD has a low mortality risk, high cure rate, and high event-free survival rate after a median follow-up of 5-6 years. However, matched donors are found in only about 20% of the patients. A boy aged 8 years with SCD had a sister, <2 years old, a fully compatible donor...

BACKGROUND AIMS: Primary hematopoietic stem and progenitor cells (HSPCs) are key components of cell-based therapies for blood disorders and are thus the authentic substrate for related research. We propose that ubiquitous small-volume diagnostic samples represent a readily available and as yet untapped resource of primary patient-derived cells for cell- and gene-therapy studies. METHODS: In the present study we compare isolation and storage methods for HSPCs from normal and thalassemic small-volume blood samples, considering genotype, density-gradient versus lysis-based cell isolation and cryostorage media with different serum contents...

This paper gives insight into the Islamic bioethical discussion on harvesting and using human embryonic (hESC) and adult stem cells. It describes some of the Islamic legal mechanisms involved in the bioethical discourse among Muslims. As the contemporary Islamic bioethical discourse is very diverse, the paper focuses on the critical discussion of related resolutions of the Saudi-based Islamic Fiqh Academy due to the esteem in which the IFA is held in the Islamic world and the pertinence of their rulings on this issue...

Fanconi anemia (FA) is characterized by congenital malformations, progressive bone marrow failure, and predisposition to malignancy. Hematopoietic stem cell transplantation is used to treat FA, and best results are attained with sibling donors who are human leukocyte antigen (HLA) identical matches. Preimplantation genetic diagnosis (PGD) offers parents of an affected child the opportunity to have an unaffected child who is an HLA match. While some research has investigated parents' experiences during the PGD process, no published studies specifically address factors influencing their decision-making process and long-term interpersonal outcomes...

Therapeutic tourism is a recent phenomenon in public health and has had repercussions among people with disabilities. Virtual social networks have enabled people to organize themselves to discover ways and means of seeking unconventional treatments in China. In this context, foreign biotech companies have offered experimental cell treatment therapies. In this work, netnography (conducting ethnographic research online) was conducted on the blogs of 58 people who organized campaigns to carry out treatment in China...

Although mesenchymal stem cells are used in numerous clinical trials, the safety of their application is still a matter of concern. We have analysed the clinical results of the autologous adipose-derived stem cell treatment (stromal vascular fraction (SVF) containing adipose-derived stem cells, endothelial progenitors, and blood mononuclear cells) for orthopedic (cartilage, bone, tendon, or combined joint injuries) and neurologic (multiple sclerosis) diseases. Methods of adipose tissue collection, cell isolation and purification, and resulting cell numbers, viability, and morphology were considered, and patient's age, sex, disease type, and method of cell administration (cell numbers per single application, treatment numbers and frequency, and methods of cell implantation) were analysed and searched for the unwanted clinical effects...

A central principle of bioethics is "subject autonomy," the acknowledgement of the primacy of the informed consent of the subject of research. Autonomy requires informed consent - the assurance that the research participant is informed about the possible risks and benefits of the research. In fact, informed consent is difficult when a single drug is being tested, although subjects have a baseline understanding of the testing of a pharmacological agent and the understanding that they can stop taking the drug if there were an adverse event...

Hiroshi Mizuno
Production of human fertilized embryos by using germ cells derived from pluripotent stem cells (PSCs) entails ethical issues that differ fundamentally depending on the aim. If the aim is solely to conduct research, then embryo generation, utilization and destruction must respect for the human embryo as having the innate potential to develop into a human being. If the aim is human reproduction, this technology must never be used to manipulate human life, confuse social order, or negatively affect future generations...

BACKGROUND: Turkey, with a Muslim population of officially over 99 %, is one of the few secular states in the Muslim world. Although state institutions are not based on Islamic juridical and ethical norms, the latter play a significant role in defining people's attitudes towards controversial issues in the modern world, especially when backed by opinions of Muslim scholars living in Turkey. Accordingly, opinions of Muslim scholars undoubtedly have an important effect on bioethical decisions made by institutions and individuals...

In a commentary published in The Lancet on January 2016, Giuseppe Remuzzi and Richard Horton, analyse the origin of the decline of the Italian primacy in biomedical science. Among the others, the existence of Italian political groups «which oppose science simply to please the Church and to achieve political gain» was considered as detrimental for advancing research in such areas as assisted reproduction or embryonic stem cell research. Some hope for a change is raised, in the opinion of Remuzzi and Horton, by the more open attitude toward science of pope Francis...

AIM: The inherent uncertainty of first-in-human trials, combined with the technical complexity of pluripotent stem cells (PSCs), makes early phase PSC studies ethically challenging. Conducting parallel bioethics research based on experiences and views of professionals in the stem cell field is therefore important. MATERIALS & METHODS: We conducted semistructured interviews with various stakeholders to get a lay of the land of ethical issues professionals find relevant to the translation of PSCs...

INTRODUCTION: During the last few decades, cell-based therapies have shown great potential to treat patients with lung diseases. It has been proposed that the administration of cells into an injured lung could be considered as a therapeutic method to repair and replace lost lung tissue. Using this method, transplanted cells with the ability to proliferate and differentiate into alveolar cells, have been suggested as a therapeutic strategy for IPF treatment. AREAS COVERED: In this review, the latest investigations using various types of cells for IPF therapy have been presented...

Nik Brown, Rosalind Williams
Umbilical cord blood (UCB) has become the focus of intense efforts to collect, screen and bank haematopoietic stem cells (HSCs) in hundreds of repositories around the world. UCB banking has developed through a broad spectrum of overlapping banking practices, sectors and institutional forms. Superficially at least, these sectors have been widely distinguished in bioethical and policy literature between notions of the 'public' and the 'private', the commons and the market respectively. Our purpose in this paper is to reflect more critically on these distinctions and to articulate the complex practical and hybrid nature of cord blood as a 'bio-object' that straddles binary conceptions of the blood economies...
