Recent developments in stem cell research – Podcast

This post is associated with a BioethicsBytes podcast on recent developments in stem cell research.  The episode focuses on two scientific papers published at the end of August 2006.  These are:

Klimanskaya I., Chung Y., Becker S., Lu S.J. and Lanza R. (2006) Human embryonic stem cell lines derived from single blastomeres Nature Eprint ahead of publication [PubMed]

Takahashi Y. and Yamanaka S. (2006) Induction of pluripotent stem cells from mouse embryonic and adult fibroblast cultures by defined factors Cell 126:663-676 [PubMed]

Reference is also made to an article from the Daily Mail:
MacRae F. (2006) Stem cells created without harming embryos Daily Mail August 23rd 2006 [link]

One Response to Recent developments in stem cell research – Podcast

  1. In the podcast, I discuss the recent experiment where researchers have combined PGD technology with stem cell research breakthroughs to achieve an “ethical” route to stem cells. I suggest that although the work has been very overstated, the team from Advanced Cell Technologies may have been unfairly accused of causing that hype since their paper in Nature makes it clear that they have used more than one cell from each embryo, and implicitly that the embryos were destroyed. However, a subsequent editorial in Nature (Alison Abbott, September 7th, http://www.nature.com/nature/journal/v443/n7107/full/443012a.html) points out that Robert Lanza, the lead researcher on the paper, has contributed to the misleading reporting of their experiments when he stated in the Nature Podcast that week that “What we have done, for the first time, is to actually create human embryonic stem cells without destroying the embryo itself.” This DOES seem to be an inaccurate account of the work.
