Biodiversity and perceptions of risk: Reactions to the use of a single donor for stem-cell-derived red blood cell transfusions

Blood transfusion is a well-accepted medical technology that currently relies on a supply of red blood cells from many thousands of altruistic donors. Cultured red blood cells using stem cell technology could offer a replacement technology, providing a limitless supply of red blood cells from a single source. This project used interviews and focus groups to explore the views of a wide range of publics towards cultured red blood cells. This paper explores how participants referred to a lack of biodiversity in cultured red blood cells in three ways. The first was as a comparison to GM crops, with concern over a monopoly on blood supplies. The second was a perceived increased risk associated with a single source of blood. Thirdly participants saw the lack of biodiversity as a threat to the altruistic nature of blood donation from multiple donors.
