This blog will have two parts. In this first entry, I present will discuss a recent case of stem cell fraud and the subsequent blog entry will discuss possible lessons to learn appearing next month.
The tale begins when Woo-Suk Hwang, a once celebrated hero of South Korea, claimed to have made the first, patient-specific human embryonic stem cell (hES) line through a technique called somatic cell nuclear transfer (commonly referred to as research or therapeutic cloning). This study was soon after proven to be fraudulent. Not to get into too many details, but this technique requires obtaining ova from women providers, enucleating its genetic material, and placing the nucleus from a somatic cell and parthenogenically activating the egg. This initiates embryonic development and at about day 3-4 of development (where the embryo is at the blastocyst stage), hES cells can be isolated from the inner cell mass of blastocysts. This incredible feat in stem cell research was published in Science in 2004 and another study in 2005. In 2006, Hwang was discredited for fabricating results and after an investigation, he was convicted for embezzlement and bioethical allegations. He embezzled approximately 830 million won (US $700,000) of government funds and apparently used 2,200 eggs obtained from his female postgraduate students and junior researchers. All wasted!
