Hwang filed a complaint with prosecutors last Friday that some of the stem cell lines his team created were replaced by those created at Mizmedi Hospital, which had collaborated with his research team.
Roe said that while the university's investigation found that the fertilized eggs came from Mizmedi, probing into any possible switch is beyond the scope of the panel.
Prosecutors said last week they are waiting for the university investigation to be completed before launching their own investigation.
Hwang's whereabouts were not known and he could not immediately be reached for comment. His mobile phone number has been changed.
