South Korean clone expert Hwang Woo- suk on Friday said his team has technology to clone embryonic stem cells and had produced the cells in its research.

Hwang made the remarks at a press conference held at the Seoul National University.

However, at the televised news conference, the professor admitted some of the cloned embryonic stem cells in his research were contaminated and it was impossible to keep them alive.

In May this year, Hwang's team announced in a paper published in US journal Science that it had successfully cloned 11 different stem cells tailored to individual patients, paving the way for future development of therapies for hard-to-cure diseases.

Hwang's news conference came one day after a co-author of Hwang "s paper alleged Hwang fabricated partial images of the embryonic stem cells described in Hwang's paper.
