Safe Stem Cells Produced From Adult Cells

hackingbear writes "Wired, citing a paper published in Science magazine, reports that Harvard scientists may have found a safer way of giving a flake of skin the biologically alchemical powers of embryonic stem cells by turning adult cells into versatile, embryonic-like cells without causing permanent damage. The technique involves 'adding cell-reprogramming genes to adenoviruses, a type of virus that infects cells without affecting their DNA.' Four-month trials on mice demonstrated that the resulting stem cells are free from unpredictable cancer-inducing mutations. This is definitely a breakthrough in stem cell research." Additional coverage is available at Yahoo, and Science hosts the research paper, although you'll need a subscription to see more than the abstract.

Re:Only on mice, for now

Instead we're faced with the new controversy that every skin cell you shed can be considered an embryo that, with the correct application of medical science, can now become a child.

Scratching yourself will now mean you're killing babies!

Or, perhaps you're trying to create an evil clone army with all those cells?

There's plenty of material and interpretations for anyone who wants to find controversy.

As someone who considers "humane killing" an oxymoron of the first degree, I'm fine with the idea. The person being killed probably doesn't care much whether he's injected with a lethal poison or shot in the head. The person needing a transplant, on the other hand, cares very much about living a normal life.

Similarly, the embryos are already being created and destroyed en masse by fertility clinics. (And yet, for some reason, pro-lifers never complain about that.) Does the embryo care whether it's grown into organ tissue or thrown in the trash? Does a person suffering from a degenerative disease care about a cure?
