S Korea stem cell success faked
A South Korean cloning pioneer has admitted fabricating results in key stem cell research, a colleague claims.
At least nine of 11 stem cell colonies used in a landmark research paper by Dr Hwang Woo-suk were faked, said Roh Sung-il, who collaborated on the paper.
Dr Hwang wants the US journal Science to withdraw his paper on stem cell cloning, Mr Roh said
