Hwang's Ba-ack

Disgraced stem cell researcher Hwang Woo-suk says he has cloned pig stem cells, according to a report in the Korea Times that a post at The Scientist points to. Hwang is now at the Sooam Biotech Research Center and his colleague Hyun Sang-hwan says, "We believe the research has significant meaning, as we established the process and techniques of creating stem cell lines from the cloned embryos of pigs." Hyun said the study was to be published in Zygote and he declined to elaborate on the methods used in the study or disclose how many lines were produced.
