This article, published in the online journal PLoS ONE, examines the impact of collaboration on publication significance in the United States and the United Kingdom, world leaders in stem cell research with disparate policies. The findings suggest that national stem cell policy differences and regulatory mechanisms driving international stem cell research in both countries did not affect the frequency of international collaborations, or even the countries with which the U.S. and U.K. most often collaborated.
