Children's Hospital Boston researcher George Daley, MD, PhD, sheds new light on the now-discredited Korean embryonic stem cell lines. In this clip, Daley discusses the three ways to make embryonic stem cells and how the Korean stem cells were actually created through parthenogenesis, a process that creates an embryo from an unfertilized egg.

  • The fact that the Korean stem cell line was derived from parthenogenesis was suggested in the Seoul National University Investing Committee's Final Report (January 2006) and was confirmed in the Supplement (May 2006) to the final report.

    The confirmation was based on the examination of 5 differentially methylated regions and 96 short tandem repeat markers. The suplement shows that the cells are from an oocyte alone and the characteristic pattern of parthenogenesis. Long before Daley's work.
