The Korean veterinarian, Woo Suk Hwang,paid for and otherwise procured hundreds - maybe a thousand - of human oocytes that were supposedly used in his now-debunked research to produce human cloned embryonic stem cells. (For history - see this AAAS press release from May which emphatically repeats the "unpaid donor" line)

What actually happened to those cells?
