Health research is increasingly being conducted on a global scale, particularly in the developing world to address leading causes of morbidity and mortality. While research interest has increased, building scientific capacity in the developing world has not kept pace. This often leads to the export of human tissue (defined broadly) from the developing to the developed world for analysis. These practices raise a number of important ethical issues that require attention.

One important sense of 'global ethics' concerns the applied ethical issues arising in the context of economic globalisation. This article contends that we are beginning to witness the economic commodification and, concomitantly, the globalisation, of human tissue and the human genome. Policy-makers and local research ethics committees need to be aware that the relevant ethical questions are no longer confined to their old national or subnational context. A shift from questions of personal autonomy and identity can therefore be expected-towards the (...) more problematic issues of justice, exploitation and distribution. Here we can learn from the distinctions drawn in legal philosophy, such as the notion of property as a 'bundle' of rights, from which we may choose rights favouring the interests of vulnerable populations. We may also wish to apply the distinctions drawn by Calabresi and Melamed between pure property rules, modified alienability rules, and pure non-property regimes. Global ethics also concerns issues of value disparity across cultures, directing our attention to the moral beliefs of indigenous peoples, for example, whose DNA or tissue is increasingly of commercial importance. In examining case examples from Tonga and Aotearoa/new Zealand, I will consider the impact of indigenous belief systems and of neo-colonialism on indigenous peoples' perceptions of Western researchers. It is clear that many indigenous peoples reject both the pure property system and any modifications, insisting on a pure non-property regime. How can they then be protected in a globalised market system that so far favours the opposite end of the spectrum? (shrink)

Background Health research is increasingly being conducted on a global scale, particularly in the developing world to address leading causes of morbidity and mortality. While research interest has increased, building scientific capacity in the developing world has not kept pace. This often leads to the export of human tissue from the developing to the developed world for analysis. These practices raise a number of important ethical issues that require attention. Discussion In the developed world, there is great heterogeneity of regulatory (...) practices regarding human tissues. In this paper, we outline the salient ethical issues raised by tissue exportation, review the current ethical guidelines and norms, review the literature on what is known empirically about perceptions and practices with respect to tissue exportation from the developing to the developed world, set out what needs to be known in terms of a research agenda, and outline what needs to be done immediately in terms of setting best practices. We argue that the current status of tissue exportation is ambiguous and requires clarification lest problems that have plagued the developed world occur in the context of global heath research with attendant worsening of inequities. Central to solutions to current ethical concerns entail moving beyond concern with individual level consent and embracing a robust interaction with communities engaged in research. Conclusion Greater attention to community engagement is required to understand the diverse issues associated with tissue exportation. (shrink)
