Regenerating movements: embryonic stem cells and the politics of potentiality.

This paper develops a theoretical frame for analysing social movements in/and biomedicine. Drawing from work in social movement theory and science and technology studies, the paper describes the field of biotechnology as the material/imagined space of contemporary biopolitics in the contemporary United States. Interviews with activists from four social movements, websites and written material are examined, and two processes of knowledge construction were found to be central in constituting the field of biotechnology. These processes open up multiple sites for citizen participation in the construction of scientific knowledge.
