As scientists await Obama reauthorizing federal funding of embryonic stem cell research and the FDA approves the first clinical trials using embryonic stem cell treatments, there is an important case report that highlights the potential safety issues with putting stem cells in humans. Amariglio et al. report a case in PLoS Medicine of a boy…

I was struck by this story on NPR about so-called “stem cell tourists.” Stem cell tourists are parents taking their children to China for injections of stem cells in hopes of curing a wide variety of diseases. I want to convey at least in some small way what an insanely bad idea this is: Jena…

Keeping with my attempt to actually do book reviews, I have the first of what will hopefully be a continuing series. I am reviewing Stem Cell Century by UCLA Law Professor and Volokh Conspiracy contributor Russell Korobkin — with Stephen Munzer in some chapters. This book examines the legal, ethical and policy-related issues in stem…

Evidence has been found for the stem cell theory of cancer development. For those of you not aware of this theory, it holds that cancers originate from cells that have inadequately differentiated from their stem cell origins. This would contrast with more standard theories of cancer development that have cells de-differentiating from a more mature…

Ethical Stem Cells Redux

In August, there was a big press tizzy about so-called ethical stem cells. In the paper, a group headed by Robert Lanza working at a company called Advanced Cell Technology claimed that they could take a single cell from a human morula and create a embryonic stem cell line from that cell. Admittedly, this was…

Ethical Stem Cells?

The press is all in a tizzy about so-called ethical stem cells, but this still indicates a really limited understanding of how embryonic stem (ES) cells work. (Frankly, if I had a dollar for every time I read bad reporting on ES cells, you and I would not be talking. I would be Tahiti…with Natalie…
