A South Korean investigation panel has concluded disgraced scientist Hwang Woo-suk and his team provided no data to prove a claim they had produced tailored embryonic stem cells.
Professor Hwang could now face possible criminal charges. Hwang resigned from his post at Seoul National University last week and apologised for the scandal. However, he maintained that the science behind his work was sound. In May, Hwang published a paper saying his team had extracted material from cloned human embryos that identically matched the DNA of 11 patients. But a university panel said last week that all 11 sets of data were derived from only two stem cell lines. Now it says two cells said to be stem cells were really human egg cells supplied by a Seoul hospital. Hwang’s team made the news in August by announcing it had produced the world’s first cloned dog.
