Quote:
Josephine Quintavalle, of Comment on Reproductive Ethics, said: "News that embryonic stem cells can be created successfully from human cells without cloning, without using human embryos or human eggs, or without getting involved in the creation of animal-human embryos, is most warmly welcomed.
"We congratulate these world-class scientists who have had the courage to state their change of tack so cogently.
"For once we have better science coinciding with better ethics."

dear lord ... as if this is the first time scientific research has been performed in an ethical manner
I suspect this idiot didn't read, nor would be able to understand the research data that was published. If he did read it (and could comprehend it) he might have noticed that the normal skin cells were "transformed" into stem cells using 4 oncogenes. I use the word "transformed" because to a cancer biologist, "transformed" means cancer. The procedure used in this study is the same procedure that Weinberg used to "transform" normal skin cells into cancer cells.
In fact, these "stem cells" form teratomas, and 20% of the chimeric mice derived from these "stem cells" get cancer. I'd bet my bottom dollar this number would be closer to 100% if they extended the end-point of their study a few weeks.
This is not a criticism of the research. The authors basically say the same thing I just did in their discussion. Unfortunately, the BBC gave this guy a voice and it's going to skew public perception. This is not a replacement for embryonic stem cells. With years/decades of research, adult cells may be converted into embryonic-like stem cells without being tumorigenic; or they could just use actual embryonic stem cells now.
