Despite the political nature of stem cell research, this area of science continues to flourish in the United States. In 2011, the NIH funded approximately US$1.2 billion in stem cell research — a steady increase from past years — with US$123 million devoted to human embryonic stem cells. According to the ISI Web of Science, more than 4,000 U.S.-authored stem cell publications were produced in 2011, accounting for approximately 38 percent of the world total. Approximately one-quarter of these publications were collaborations with authors from other countries.
In this article, the authors compare two different approaches to establishing stem cell policy: a defined policy (U.K.) and a changing policy (U.S.). The U.K. has a clear and precise policy, agreed upon and supported by lawmakers, scientists and the public. By contrast, U.S. federal policy is continuously being updated based on balancing political ideologies and advances in science, and it only regulates federal funding. By investigating these contrasting policy approaches, the authors hope to demonstrate the impact of policy on stem cell research and public opinion.
