Scientists Grow Blood Vessels Using Skin Cells

rubberbando writes "The new york times is running a story about how scientists have discovered a way to grow new blood vessels using skin cells. Since the blood vessels are grown using the patient's own skin cells, there isn't any chance for rejection. This looks to be quite a boon for people who have several damaged blood vessels from diseases such as diabetes. Perhaps one day they will be able to apply this technology/technique to creating other parts of the body and rid us of the whole stem cell controversy. Only time will tell."

No controversy? Hah!

I doubt that it'll rid us of the controversy... because by the time that becomes possible, cloning or genetic modification of some other sort will also have also become possible, and that'll just pick up where the stem cell controversy left off, probably with many of the same arguments on both sides.

Get rid of the stem cell controversy?

We can't get rid of something that's projected onto the situation by people who are nervous/scared about what the bio-sciences say about their world view. The stem cell worriers aren't really worried about stem cells or their source, they're worried about how close we're getting to a comfortable understanding of cellular mechanics. That takes the mystery out of a lot things, and devalues mystical explanations (and those social institutions that rely upon them for clout).

Growing new body parts out of other body parts will still freak out a certain number of people, no matter what. If it's not the stem cell faux-controversy, it will be the "only rich people can afford this treatment, so it's evil" crowd or their various other counterparts.

Oh please... The debate over Stem cells has nothing to do with scientific understanding of cellular mechanics. If that were the case, Watson and Crick would have been burned at the stake decades ago. No other research involving cellular mechanics has reached this level of public scrutiny. I've never heard anyone debate the ethics of cell-surface recognition proteins or origins of the mitochondria in cells. Let's be honest. The whole stem-cell debate is merely a veiled front for the larger fight over abortion. (I use the word fight because "debate" hardly fits.)

Here's how it happened:

1. The most interesting and scientifically-valuable stem cells are found in developing embryos.
2. Studying these cells requires the destruction of the embryo.
3. This raises the ugly question: if destroying an embryo for research is okay, what makes an abortion any different?
4. Fight ensues. Everybody all the sudden becomes an expert on cellular biology.

That takes the mystery out of a lot things, and devalues mystical explanations (and those social institutions that rely upon them for clout).

Bullshit. "Social instiutions that rely on mystical explanations"? Do you mean "religions"? Why don't you just say it? ...Religions... See how easy that was?

Regardless, science doesn't debunk the larger, more important claims of religion. It can't. Learning about cellular theory doesn't debunk the existence of God. Learning physics doesn't mean that God couldn't temporarily violate the laws of physics at a whim--you know, being omnipotent and all.

Religion and God are meta-physical concepts, while science is the study of the physical world. The two aren't mutually exclusive ideas. A scientist can just as easily believe in a religion as an atheist in science.
