Seoul, South Korea ? South Korea’s top university said today it has received some DNA test results for its investigation of disgraced stem cell researcher Hwang Woo-suk and it will complete a final report on the findings next week.

The investigation panel at Seoul National University commissioned the DNA tests to determine whether Hwang ever created patient-matched stem cells as he claimed in a May article in the journal Science. On Friday, the panel said at least nine of 11 stem cell lines that Hwang had claimed to create were faked.

Some test results have been received, the panel said in a statement, adding it would take a few more days to get a full analysis.

No details of the test results have been released so far.

Last week, Hwang apologized for the scandal and stepped down as professor at the university, but still insisted his team had developed the technology to create patient-matched stem cells.
