Prosecutors confirmed that cloning expert Hwang Woo-Suk had fabricated key research, raising the likelihood that criminal charges could be filed against the disgraced South Korea scientist. Prosecutors said they had used DNA testing to prove that the researcher never created stem cells tailored to individuals as he had claimed in a 2005 scientific paper.None of the cells tested were found to match those that Hwang claimed he had created in a landmark paper published in US journal Science.The results corroborated the findings of a scientific panel at Seoul National University who investigated Hwang last month.
