Stem cells from testes

What do they consider a "relatively simple process"? A rubber band and a pair of shears is relatively simple, but I'll be damned if you'll hear me praising the advancement.

Now, if this process involves kitten killing it's a major advancement to science.

You know, if we can persuade them it's a choice between this or stem cells from embryos, the ultraconservatives will probably suddenly start raving about how awesome embryonic stem cells are :P


Actually, I'm sure every month I hear about a new way to get stem cells, even ones that can be used like embryonic ones, but they always disappear after a while and nothing visible is done about them.
Are they all being researched quietly somewhere, or do people just discover these things and move on?

If I was slightly more prone to conspiracy-theorist-type thinking, I'd suggest that many people involved have ulterior motives to keep stem cell issues as a subset of the abortion debate.
It does seem like every time stem cells come up the whole abortion thing rears it's head, even when the cells are from skin or something.

Actually the pro-life people I know all support adult stem cell research. I don't think "Balls are gross" is going to be legitimate reason for them to suddenly change their position on killing embryos. The obvious advantage is that you could grow your own stem cells into tissue with your own DNA. From my basic understanding of transplants, I imagine this would be superior to a combination of two strangers' DNA. The only red flag I could see coming from the Evangelicals would be that this is a slippery slope to human cloning, and I think that's a rather weak argument.

I was thinking more of a knee-jerk "Stay away from my balls!" sort of thing rather than anything rational.

That's about the 5th new way to get stem cells I've heard of so far this year. When are they going to say "we did it" and start applying them?

Once they're sure those stem cells don't randomly turn into cancer 2 years down the road, which happens with at least one method i've heard about. Embryonic stem cells are so great because we know so much about them compared with the other methods.

Sorry girls, I guess you just don’t have the balls to get cured.

Right now, the ability to make stem cells is more of a solution looking for a problem. Until we can reliably differentiate the cells into the required tissue type, then any source of them is helping to provide raw material for research that is sorely needed. In contrast to the above I would happily and willingly undergo biopsy or similar procedure to help generate this raw material for research, as long as the correct controls were in place to avoid misuse.

Maybe the reason that these stories pop up and then disappear is that stem cells are at present a largely untapped potential. When the media will go nuts over this is when the next advance is made. I would imagine that the way things are going, growing new teeth has the potential to be one of the first "mass-market" applications.

I'd like to think that there are stem cell projects that are being held back due to controversy over the source of the cells, so I'm glad that they're finding different methods of getting them. Dr. Hobbs hit some controversy when he was transplanting bone marrow from one person into another, yet now its a supported practice. Stem cells are only a few steps farther from undifferentiated than the classification of bone marrow cells, and the fact that we can extract them from healthy individuals (and keep them healthy) should make stem cell research a reasonably acceptable practice. The biggest hurdle is making the darn things turn into what we want them to become, which took fetus developmental evolution quite a while.

Having clinics where college kids can make a quick buck by donating stem cells for research (from not only the testes but eventually other parts of the body) would be a great way of advancing research by the amount of material both industries and academia can work with. They would have to work on the security and moral concerns.

I can't think of anything useful that a rubber band and shears could actually do together. It does sound like a recipe for an ambulance trip though.
