Stem Cells Restore Sight For Corneal Disease Patients 223
Sean0michael writes "Australian scientists have restored the sight of three human test subjects using stem cells cultured in contact lenses. All the patients were blind in only one eye. Two were legally blind, but can now read the big letters on an eye chart. The third could read the first few lines, but is now able to pass a driver's test. The University of New South Wales reports that these patients all had damaged corneas, and the stem cells came from each person's good eye. The best part: the procedure is inexpensive, raising hopes for being able to push this to the third world sooner than other, more expensive medications."

Embryonic stem cells don't come from aborted fetuses. They come from in vitro fertilization. ESC are harvested 5 days after fertilization, abortions aren't performed 5 days after fertilization because you wouldn't know.

In fact, I am not sure that there has been even one single break through that wasn't from adult stem cells.
That's due to your own ignorance not any actual facts. I found one example just in 2 seconds of googling. This FDA approved study [cnn.com] was based on a previous trial that was able to successfully restore locomotion to those with spinal cord injuries. It is not even the only example just the first one that I found.

The article doesn't go into very much detail on what the stem cells really were or how the were produced,
They weren't produced. They were somatic stem cells that were in the patients good eyes.
so I assume what they refer to as "stem cells" are really multipotent stem cells (or so-called progenitor cells [wikipedia.org])
No, you would be wrong. As the summary and the article state these are adult stem cells [wikipedia.org] or somatic stem cells as they are also called.

Now you've done it.
People had the image of evil scientists watching abortions being performed through a hole in the wall, rubbing their hands together and twirling their mustaches in sadistic anticipation of fresh, fetal stem cells. It worked out well. They had a target (that didn't exist) they could all agree to hate.
Now those people will have to imagine evil test tubes and deal with the fact that many of them have used such services.
It's only a matter of time before we hear them cry out that they were raped by these doctors who harvested their children for profit and the evils of science, without having any reason to believe that it actually happened to them.

"some people feel are highly unethical actions to get more,"
yeah, well I am tired of 'some people' telling me nonsense becasue of there 'beliefs'. Ignoring the fact that they are the scraps of In Vitro and not specifically harvest for research.
"...used and duplicated forever."
No, they can't. Tehre are serious problems with the techniques which make them not as usable and in many cases worthless for research.
Who the fuck started spreading that lie?
