A probe into the work of South Korean stem cell researcher Woo Suk Hwang, DVM, PhD, concluded that two articles detailing purported advances in human cloning were fabricated, according to a summary report posted online on January 10 by Seoul National University's Investigation Committee (http://www.snu.ac.kr/). Two days later, Science editorially retracted the article.
In the articles, Hwang and colleagues claimed to have created the world's first cloned human embryos (Hwang WS et al. Science. 2005;308:1777-1783) and to have established stem cell lines from a number of individuals, achieved in each case by transferring the nucleus of a somatic cell from the individual into an enucleated human egg (Hwang WS et al. Science. 2004;303:1669-1674). The university did uphold Hwang's claim in 2004 to have performed the world's first cloning of a dog.
