Abstract

The NIH, which has an annual budget of over US$31 billion, is the world's largest biomedical research agency and is a major strength for science in the USA. Despite the political nature of stem cell research, this area of science has flourished across the country. In 2010, the NIH funded approximately US$1.3 billion in stem cell research. According to the ISI Web of Science, more than 4000 US-authored stem cell publications were produced in 2010 - approximately 40% of the world total. The average citation rate was 4.12 per article, with six articles amassing 100 citations in less than 18 months after release.

摘要

美国国立卫生研究院（NIH）每年的预算超过 310 亿美元，是世界上最大的生物医学研究机构，也是美国科学的主要力量。尽管干细胞研究具有政治性，但该领域的科学在美国各地都蓬勃发展。2010 年，NIH 为干细胞研究提供了约 13 亿美元的资金。根据 ISI Web of Science 的数据，2010 年有超过 4000 篇由美国作者撰写的干细胞出版物，约占全球总数的 40%。平均引用率为每篇文章 4.12 次，其中 6 篇文章在发布后不到 18 个月内就获得了 100 次引用。
