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.
Conservatives have no problem with stem-cell research. The problem is when the stem cells are harvested from a human embryo - during the process we end a human life. The main question about embryonic stem-cells was 'Is it right to kill a human being to potentially save other lives?' With this new breakthrough, it could be possible to save many lives without killing a potential human life.
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.
It's not too far unlike the the reason why labor laws generally do not allow you to opt-out (minimum wage, lunch, etc). While it is understandable that workers may want to on their own accord, it becomes extremely difficult to prove that they weren't encouraged to by their employer.
Similarly, if we're allowed to harvest organ from people we killed on purpose, how can we be sure that the person was killed for legitimate reasons? So we look to legislation to minimize any positive side effects to a person's death.
And likewise, while embryos might not count as human life, they are human. By allowing people to harvest stem cells from them, you are putting utility in destroying human could-be-life. The end result is not awfully far from _farming_ human could-be-life since, as above, proving things like 'abandoned' is difficult. This doesn't sit well with a lot of people, and especially so with those that view embryos are full fledged human life.
many people believe "Human Life" doesn't begin until after the state that embryo's are harvested.
yes, but this new discovery neatly side- steps that problem.
and for those above who say that McCain will find some way to construe it as unethical, the pope has said that adult stem cell research is fine. Pope endorses adult stem-cell research (catholicnews.com) If the pope is good with it, i don't see any elected official having a problem with it.
"The possibilities opened up by this new chapter in research are in themselves fascinating" because adult stem-cell studies have pointed to actual and potential cures of degenerative diseases that would otherwise lead to disabilities or death, the pope said at an audience for participants attending a Vatican-sponsored congress on stem-cell therapy.
