Methodological note: We draw on interviews with ten biomedical scientists who work in one leading beta cell/stem cell laboratory in England. These scientists can be seen as part of the global community of beta cell biologists; to preserve anonymity, we do not include their specific titles. Following ethics committee approval, interviews were conducted that lasted between one and two hours, took place within the laboratory offices, and (with permission) were taped and transcribed. Open-ended questions and an informal interview schedule were used, in order to encourage scientists to speak in their own words about their experiences. Transcripts were analyzed by content for emergent themes, which were then coded. The research team discussed the data and the analysis, which enabled different perspectives to be incorporated, and added to the richness and validity of the analysis, Two of the researchers (SW, CW) also observed and interacted with the scientists in meetings, in the laboratory

Informal conversations with scientists took place in all these settings. In addition, one of the researchers (SW) participated in nine laboratory workshops for postgraduate biomedical scientists, learning various laboratory techniques. While experience in these and other settings supports the present analysis, we are aware of the limitations of the present sample; in consequence, we treat the analysis as an exploratory route into the data that might, with luck, open up broader considerations around the temporality and politics of technoscience.

The experimenters' regress refers to the observation that scientific controversies typically entail disagreements not only concerning the factuality or artefactuallty of scientific data, but also about the actual quality of other scientists' work and, indeed, their character. The upshot is that no experiment can serve to resolve the controversy, hence the regress where claim and counterclaim proliferate. For a classic statement of this phenomenon, see Harry M. Collins, Changing Order (London: Sage, 1985).

Such a dual perspective on hESCs as potential technical objects and contemporary eplstemic things resonates with Knorr Cetina's critique of technical objects as overly objectified, not least in their ongoing practical problematization in the doings of experimental science (e.g, was such and such a technically objectified procedure properly followed, In the present case, we note that such objectification has utility within the extended politics of hESC research, even as it is routinely unraveled.

While we do not expand on this in the present paper, these accounts are spatlotemporal in the sense that they enact both a temporality (in relation to hope, or optimism, or, more broadly the future and expectations) and associated spatialities, in that certain futures are aligned with certain distances from the exigencies of the laboratory bench or indeed, any setting where tacit skilfulness is bound up with dealing with uncertainty and contingency, settings that might also include the crafting of policy or the rendering of ethical judgment

Inevitably, there are further heterogeneities to be taken into account. Needless to say, the present paper assumes the materlal-semiotic heterogeneity of the assemblages in which (human embryonic) stem cells are rendered, and that stem cells trace. What immediately interests us are certain social heterogeneities, specifically the ethical and the institutional. We focus on these partly because of their instantiation in the data, but also because they serve as a grounds for rethinking (some of) the enactments of stem cell politics.

In some ways this analysis resembles the formulation of the regime of truth and regime of hope put forward by Moreira and Palladino. Where the present paper diverges from their treatment is in regarding the distinction between hope and truth as rather more blurred (as evidenced in our expanded treatment of the notion of an eplstemic thing). That is to say, the truthful can be hopeful, and the hopeful can be dispiriting. See Tiago Moreira and Paulo Palladino, Between Truth and Hope: On Parkinson's Disease, Neurotransplantation and the Production of the Self, History of the Human Sciences 18 (2005): 55-82.

One might say that, as phronesic things, hESCs, in Whitehead's terms, concresce out of these disparate concerns, to be subsequently disaggregated or disambiguated in the talk of our respondent scientists. In the process of such enactments, scientists make both themselves and their audiences (most especially via the interviews). On the matter of concrescence, see Alfred North Whitehead, Process and Reality (Cambridge: Cambridge University Press, 1929).

That notion of phronesic thing applies no less to the typology set out in the table presented above. The divisions we identify are emergent and immanent-the table is thus, in the context of this paper, presented as a thing. Yet, for other audiences, it can be presented as an object - as stabilized and transparent. Such an objectifying presentation nevertheless also enacts stem cells as phronesic things, in that its performative effects are themselves emergent and processual.

In more processual terms, and drawing on Whitehead once more, we might say that our scientists' accounts emerge out of the plasticity of the epistemic-ethical-institutional assemblage in which hESCs are embroiled, and are drawn into (prehended in) the concrescences of subsequent actual occasions of the assemblage. This is a sort of heterogeneous hermeneutics in which scientists' discourse is a material-semiotic prehension. On this score, we do not see stem cells as possessing particular qualities in themselves, these are always relational. Thus characterizations of stem cells as immortal are nonsensical: a nexus of relations needs to be in place. In other words, we need to be wary of falling into the trap of what Whitehead has called the fallacy of misplaced concreteness and concretizing abstract characteristics like this, In vitro, in order for stem cells to be immortal, certain conditions and environments need also to be reproduced hence the relationality en

In more processual terms, and drawing on Whitehead once more, we might say that our scientists' accounts emerge out of the plasticity of the epistemic-ethical-institutional assemblage in which hESCs are embroiled, and are drawn into (prehended in) the concrescences of subsequent "actual occasions" of the assemblage. This is a sort of heterogeneous hermeneutics in which scientists' discourse is a material-semiotic prehension. On this score, we do not see stem cells as possessing particular qualities in themselves - these are always relational. Thus characterizations of stem cells as "immortal" are nonsensical: a nexus of relations needs to be in place. In other words, we need to be wary of falling into the trap of what Whitehead has called the fallacy of misplaced concreteness and concretizing abstract characteristics like this, In vitro, in order for stem cells to be immortal, certain conditions and environments need also to be reproduced (hence the relationality entailed in stem cells); thus, to claim that in vitro stem cells are immortal would be to assume that, at minimum, petri dishes can reproduce themselves. See Alfred North Whitehead, Science and the Modern World (London: Free Association Books, 1926).
