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.

Seeking consent for genetic and genomic research can be challenging, particularly in populations with low literacy levels, and in emergency situations. All of these factors were relevant to the MalariaGEN study of genetic factors influencing immune responses to malaria in northern rural Ghana. This study sought to identify issues arising in practice during the enrolment of paediatric cases with severe malaria and matched healthy controls into the MalariaGEN study.

Biological sample and data transfer within and out of Africa is steeped in controversy With the H3Africa project now aiming to establish biobanks in Africa, it is essential that there are ethical and legal governance structures in place to oversee the operation of these biobanks. Such governance is essential to ensuring that donors are protected, that cultural perspectives are respected and that researchers have a ready availability of ethically sourced biological samples.

Tissues contain complex populations of cells. Like countries, which are comprised of mixed populations of people, tissues are not homogeneous. Gene expression studies that analyze entire populations of cells from tissues as a mixture are blind to this diversity. Thus, critical information is lost when studying samples rich in specialized but diverse cells such as tumors, iPS colonies, or brain tissue. High throughput methods are needed to address, model and understand the constitutive and stochastic differences between individual cells. Here, we (...) describe microfluidics technologies that utilize a combination of molecular biology and miniaturized labs on chips to study gene expression at the single cell level. We discuss how the characterization of the transcriptome of each cell in a sample will open a new field in gene expression analysis, population transcriptomics, that will change the academic and biomedical analysis of complex samples by defining them as quantified populations of single cells.

The human body is becoming hot property, a resource to be “mined,” “harvested,” patented, and traded commercially for profit as well as scientific and therapeutic advances. Under the new entrepreneurial approach to the body old tensions take on new dimensions—about consent, the fair distribution of tissues and products developed from them, the individual and cultural values represented by the body, and public policy governing the use of organs and tissues.

Studies on informed consent to medical research conducted in low or middle-income settings have increased, including empirical investigations of consent to genetic research. We investigated voluntary participation and comprehension of informed consent among women involved in a genetic epidemiological study on breast cancer in an urban setting of Nigeria comparing women in the case and control groups.

The alienation of body parts and their transformation into commodities raises questions about ownership, property rights, and about possible violation of the moral order. This article focuses on the `social life' of objects, including body parts, and the multiple meanings attached to them that are made visible in systems of exchange. The transformation of DNA obtained in blood samples into immortalized cell lines for use in the Human Genome Diversity Project is introduced as an illustration of contested commodification. The meanings (...) attached to the blood samples by those from whom they are procured and their worth to the scientists who create the cell lines are of an entirely different order. Disputes about the HGDP that have erupted since it was first planned are presented in detail, followed by a discussion of the ethics of gene prospecting and the associated politics of biocapitalism currently proliferating in the private sector.

Biobank research is potentially fruitful. It is argued that broad consent is acceptable for future research on biological material because a) the benefit is high, b) it pays respect to people’s autonomy, c) it is consistent with current practices and d) because the risk is low. Furthermore, broad consent should be allowed if information is handled safely, people can withdraw and expanded research should be approved by an ethics review board. However, these arguments are flawed and the criteria for broad (...) consent are either too restrictive to allow any research or fail to address important challenges with biobank research. Broad consent for biobank research can hide substantial ethical challenges and threaten trust in research. This does not mean that biobank research should be abandoned or that people cannot authorise future research on donated biological material. (shrink)

Most writing on informed consent in Africa highlights different cultural and social attributes that influence informed consent practices, especially in research settings. This review presents a composite picture of informed consent in Nigeria using empirical studies and legal and regulatory prescriptions, as well as clinical experience. It shows that Nigeria, like most other nations in Africa, is a mixture of sociocultural entities, and, notwithstanding the multitude of factors affecting it, informed consent is evolving along a purely Western model. Empirical studies (...) show that 70–95% of Nigerian patients report giving consent for their surgical treatments. Regulatory prescriptions and adjudicated cases in Nigeria follow the Western model of informed consent. However, adversarial legal proceedings, for a multiplicity of reasons, do not play significant roles in enforcing good medical practice in Nigeria. Gender prejudices are evident, but not a norm. Individual autonomy is recognized even when decisions are made within the family. Consent practices are influenced by the level of education, extended family system, urbanization, religious practices, and health care financing options available. All limitations notwithstanding, consent discussions improved with increasing level of education of the patients, suggesting that improved physician's knowledge and increasing awareness and education of patients can override other influences. Nigerian medical schools should restructure their teaching of medical ethics to improve the knowledge and practices of physicians. More research is needed on the preferences of the Nigerian people regarding informed consent so as to adequately train physicians and positively influence physicians' behaviors. (shrink)

Scientific interest in genomics in Africa is on the rise with a number of funding initiatives aimed specifically at supporting research in this area. Genomics research on material of African origin raises a number of important ethical issues. A prominent concern relates to sample export, which is increasingly seen by researchers and ethics committees across the continent as being problematic. The concept of genomic sovereignty proposes that unique patterns of genomic variation can be found in human populations, and that these (...) are commercially, scientifically or symbolically valuable and in need of protection against exploitation. Although it is appealing as a response to increasing concerns regarding sample export, there are a number of important conceptual problems relating to the term. It is not clear, for instance, whether it is appropriate that ownership over human genomic samples should rest with national governments. Furthermore, ethnic groups in Africa are frequently spread across multiple nation states, and protection offered in one state may not prevent researchers from accessing the same group elsewhere. Lastly, scientific evidence suggests that the assumption that genomic data is unique for population groups is false. Although the frequency with which particular variants are found can differ between groups, such genes or variants per se are not unique to any population group. In this paper, the authors describe these concerns in detail and argue that the concept of genomic sovereignty alone may not be adequate to protect the genetic resources of people of African descent.
