The Seoul National University investigative panel that probed the authenticity of Hwang Woo-suk's stem cell research has attached documents to its final report on the scandal.

The panel on Tuesday said the supplemental documents comprising some 200 pages include the results of DNA fingerprint tests on stem cell and teratoma samples and samples from the cloned dog Snuppy, and the blood of somatic cell donors received from Hwang's research team.

The panel ruled out posting the material on the Internet because of its sheer size and the inclusion of handwritten memos by panel members.
