Interestingly, Dr. Scadden, who was the senior author on this publication (the web site you referenced messed up the order of the authors),
You're right, it did...that's bizarre. Sorry for posting that one instead of the actual publication link. Actal citation is:
Wang ZZ, Au P, Chen T, Shao Y, Daheron LM, Bai H, Arzigian M, Fukumura D, Jain RK, Scadden DT. "Endothelial cells derived from human embryonic stem cells form durable blood vessels in vivo." Nat Biotechnol. 2007 Mar; 25(3):317-8. Epub 2007 Feb 25. doi:10.1038/nbt1287[...] he is very upbeat about the potential of induced pluripotent stem cells (iPS), which are a type of adult stem cell.
...as am I. I hope you realize that one path of research does not preclude the other. In fact, the results of embryonic stem cell research has led to advances in adult stem cell research, and we might find different uses for the two sources.
> Sorry, but science often operates incrementally and if you are going to play games with the wording to keep backing away from statements, then we could have done the same with adult stem cell research.
The science does operate incrementally and not without mistakes. The problem with the publication you cited is not that it was a brief note, but that it has not been followed-up by a full article. I did a search on Scadden and could not find anything relevant. It is, of course, possible that some of his collaborators took it upon themselves to do follow-up research without his participation. That would be highly unusual and would raise another red flag. However, you are welcome to do your own search and prove me wrong.
BTW, that citation link was cool - I did not realize you could embed EndNote links.
