LEARNING GOAL
• Understand ethical issues in the practice of research using this case study
LEARNING OBJECTIVES
• Identify and analyze important concepts in research misconduct and fraud using group share
• Create a concept map: make connections between different elements of this case
Hwang Rise • Feb 2004: First reported success of
creating human embryonic stem cells by cloning using somatic cell nuclear transfer method
• May 2005: 11 more stem cells from cloned human embryos using same method
• Two landmark articles published in Science
• August 2005: Hwang reported that his lab have cloned the world first dog (Snuppy) in Nature

Somatic cell nuclear transfer method (SCNT)
• Injecting genetic material from adult human cells into human eggs that had their own DNA removed

Study brings therapeutic cloning one step closer
• The technique could eventually help scientists develop ‘’ Repair Kit’’ for the treatment of many diseases using their own stem cells

The Scandal• November 2005: One of Hwang`s collaborators raised concerns regarding oocyte (egg) donations in Hwang's research and unethical conduct in the egg cell acquiring process in violation of the country's bioethics law
Science Feb 10 2006
• January 2006 : University announced that all Hwang's stem cell lines were fabricated and both Hwang's 2004 and 2005 Science papers are based on fabricated data
• Snuppy was real clone
Time cover Jan 6 2006
Indictment and trial• May 12, 2006: Indictment
– Conduct and reporting of fraudulent research
– Embezzlement and misappropriation of funds
– Violation of Bioethics and Biosafety Act 2005
• June 20, 2006: Trial• 2007: Hwang was fired from
SNU• October 26, 2009: Guilty of
embezzlement and ethics violations but not research fraud
