Science and engineering research has becoming an increasingly international phenomenon. Traditional bibliometric studies have not captured the evolution of collaborative partnerships between countries, particularly in emerging technologies such as stem cell science, in which an immense amount of investment has been made in the past decade. Analyzing over 2,800 articles from the top journals that include stem cell research in their publications, this study demonstrates the globalization of stem cell science. From 2000 to 2010, international collaborations increased from 20.9% to 36% of all stem cell publications analyzed. The United States remains the most prolific and the most dominant country in the field in terms of publications in high impact journals. But Asian countries, particularly China are steadily gaining ground. Exhibiting the largest relative growth, the percent of Chinese-authored stem cell papers grew more than ten-fold, while the percent of Chinese-authored international papers increased over seven times from 2000 to 2010. And while the percent of total stem cell publications exhibited modest growth for European countries, the percent of international publications increased more substantially, particularly in the United Kingdom. Overall, the data indicated that traditional networks of collaboration extant in 2000 still predominate in stem cell science. Although more nations are becoming involved in international collaborations and undertaking stem cell research, many of these efforts, with the exception of those in certain Asian countries, have yet to translate into publications in high impact journals.
科学和工程研究正日益成为一种国际化现象。传统的文献计量学研究未能捕捉到国家间合作关系的演变，特别是在干细胞科学等新兴技术领域，过去十年在这些技术领域投入了大量资金。本研究分析了在出版干细胞研究的顶级期刊上的 2800 多篇文章，展示了干细胞科学的全球化。从 2000 年到 2010 年，国际合作从所有分析的干细胞出版物的 20.9%增加到 36%。就高影响力期刊的出版物而言，美国仍然是该领域最富有成效和最占主导地位的国家。但是亚洲国家，特别是中国，正在稳步取得进展。中国作者的干细胞论文比例增长了 10 多倍，而中国作者的国际论文比例从 2000 年到 2010 年增长了 7 倍以上，这两个国家的增长最为显著。虽然欧洲国家的干细胞出版物总数略有增长，但国际出版物的比例增长更为显著，尤其是在英国。总体而言，数据表明，2000 年存在的传统合作网络在干细胞科学中仍然占主导地位。尽管越来越多的国家参与国际合作并开展干细胞研究，但除了某些亚洲国家外，这些努力尚未转化为高影响力期刊的出版物。
