                        The scandal over the fabrication of data purporting to 
show the cloning of human embryos deepened yesterday.

                        As South Korea's top university received some of the 
DNA test results that will be crucial for its investigation, the disgraced stem 
cell researcher Dr Hwang Woo-suk has implicated another scientist in the 
furore. Seoul National University commissioned the DNA tests to determine 
whether he ever created patient-matched stem cells via cloning, as he claimed 
in the journal Science.

                        On Friday, the panel said data on at least nine of 11 
stem cell lines that Hwang claimed to create via cloned embryos were 
fabricated. The Yonhap news agency claimed in an unconfirmed report circulating 
yesterday that the DNA tests would not clear Hwang on the remaining two stem 
cell lines.

                        It has also emerged that Hwang filed a petition with 
the Seoul central district prosecutor's office asking it to investigate whether 
his collaborators at MizMedi hospital replaced his therapeutic-cloning stem 
cells with samples from a fertility clinic.

                        He named Kim Sun-jong, a co-author of Hwang's 2005 
paper, who played a key role in developing the purported patient-specific stem 
cells from cloned human embryos.

                        "Kim Sun-jong and others disturbed the work of 
establishing the patient-tailored embryonic stem cells, throwing it into utter 
confusion," said the petition.

                        Kim, who now works at the University of Pittsburgh, 
flew to South Korea on Saturday and was questioned by a panel of experts at the 
university. He denied having replaced the cloned stem cells.
