A coyote cloned by South Korean stem cell scientist Hwang Woo-suk and his team is pictured on a farm at a wildlife protection centre in Pyeongtaek, south of Seoul, October 17, 2011. Hwang on Monday donated eight coyotes that he and his research team at the Sooam Biotech Research Foundation cloned to help the endangered species, to the Gyeonggi provincial government, local media reported. Hwang was at the heart of a research fraud case in 2005, where a team he led was found by review boards to have manipulated key data in its studies on cloning stem cells. South Korea, considered then a global leader in human embryonic stem cell research, all but put stem cell research into deep freeze as a result of the scandal.
