In all the excitement about faking a different result, he didn't realize he actually had a scientific 'first'. Nicholas Wade has the story:
Dr. Hwang said he had derived embryonic stem cells from the adult cells of a patient, but the claim was discredited after parts of his research were found to have been faked. A team of Boston scientists has now re-examined stocks of Dr. Hwang’s purported embryonic stem cells and arrived at a surprising conclusion: His embryonic stem cells were the product of parthenogenesis, or virgin birth, meaning they were derived from an unfertilized egg. [...]
Other researchers have since developed embryonic stem cells from parthenogenetic eggs, but Dr. Hwang’s team would have been the first to do so had its members recognized what they had done.
