Verdict: Hwang's human stem cells were all fakes

Abstract

The university committee investigating into scientific misconduct in the laboratory of South Korean cloner Woo Suk Hwang announced on 10 January 20005 that his claim the previous year to have cloned a human embryo was fake. The findings are a huge setback for therapeutic cloning-the idea that cloned embryos could be used as a source of patient-matched stem cells to replace damaged tissues in a range of diseases.
