Despite the political nature of stem cell research, this area of science continues to flourish in the USA. 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 4000 US-authored stem cell publications were produced in 2011, accounting for approximately 38% of the world total. Approximately a quarter of these publications were collaborations with authors from other countries.
尽管干细胞研究具有政治性，但该领域的科学在美国仍在蓬勃发展。2011 年，NIH 资助了约 12 亿美元的干细胞研究——与过去几年相比稳步增加，其中 1.23 亿美元用于人类胚胎干细胞。根据 ISI Web of Science 的数据，2011 年美国作者发表了超过 4000 篇干细胞论文，约占全球总数的 38%。这些论文中约有四分之一是与其他国家作者合作的。
