University of Manchester researchers have transformed fat tissue stem cells into nerve cells -- and now plan to develop an artificial nerve that will bring damaged limbs and organs back to life. In a study published in October's Experimental Neurology, Dr Paul Kingham and his team at the UK Centre for Tissue Regeneration (UKCTR) isolated the stem cells from the fat tissue of adult animals and differentiated them into nerve cells to be used for repair and regeneration of injured nerves. They are now about to start a trial extracting stem cells from fat tissue of volunteer adult patients, in order to compare in the laboratory human and animal stem cells.

To alloplasty before transplants (Score:2, Interesting)
It's interesting to think that in Larry Niven's "Gil 'The Arm' Hamilton" stories (collected in Flatlander [amazon.com] ) and other Known Space books organ transplants were supposed to be the rage, before eventually being supplanted by alloplasty, "gadgets instead of organs", long after. At the rate science is progressing, viable artificial solutions are going to be found for many things before transplantation would be possible.
What I wonder, though, is whether these artificial solutions will be allowed to be so much b

Would be awesome to have some heat/cold sensors to be able to somehow "detect" if something is too hot or cold!
Maybe some sort of "tactile feedback" mechanism as well so you could feel some kind of "force" if you for example come into contact with a physical object.

Re:ALS/MND (Score:5, Informative)
Unfortunately this is probably beyond the abilities of current medical science. The problem is that the nervous system grows with the limbs and organs starting from early embryonic stage; it's not something that you can entice to regrow from scratch. Probably the long term solution will be nanomachines that are injected into the body and rebuild nerves along preplanned routes, molecule by molecule. This is very appealing and also probably about 50 years away from reality.
Also, axons (the long part of the nerve cell) usually require a myelin cell wrapping along its length to boost its ability to depolarize quickly. It's not clear that these folks in Manchester were able to grow a nerve cell along with its myelin. If we knew how to do that, we could also help people with multiple sclerosis, a disease that attacks myelin specifically.
As for ALS, it's an agent or group of agents that attacks motor neurons; these agents are not fully understood. It might be possible to splice in healthy neurons here and there but you still have the myelin problem.
This kind of research announcement should not be taken as a big step forward in fixing nerve damage until they can demonstrate it in vivo. Until then, it's just another cold fusion type story.

Eventually though, I would imagine that it would be like the episode of Star Trek Enterprise when they find the race of people who are basically falling apart genetically and they have no idea why.
And then of course the old addage "Overspecialize and you breed in weakness" has many powerful implications in this as well.
Maybe I wouldn't be so scared if we weren't still completely reversing our dietary ideals every 3 years. If we can't even nail down a healthy diet (pyramid points up or down now?!), how the hell can we figure out what the ramifications of stem cell research would be on our evolutionary process?

Something that's always intrigued me about stem cell research is the concept of genetic memory. Considering the implications that this theory has on the theory of evolution, I wonder if mixing and matching stem cells, and thereby mixing genetic memories, would fuck the evolutionary process. It's the type of result that we probably wouldn't see for thousands (or tens of thousands) of years.
What I find interesting are the genetic atavisms that you get with certain species. The classic examples are cetaceans born with hind legs or humans with true tails, complete with muscles, bones, and nerves. These are throwbacks to previous points in the evolution of that species.
There was a Trek episode that had a virus do that kind of thing, Worf became a predalien and some humans became bugs. That's a bit silly since bugs aren't in our history. But it makes me wonder, are the genes still there to turn a

The rapid adaptations may simply be the selective pressure conferring an advantage on genes that where already in the population but until that point had not been particularly advantageous. You can expand this to a population splitting and each half encountering different selection pressures, and so on.
Right, but how did those genes get there in the first place? It's not like the slate is wiped clean at each speciation point and then everyone has to wait for random mutation to build up some new genetic ideas before a new set of pressures can cause a new speciation. What I'm wondering about is how often animals will be reaching back to use ancient genes to meet new evolutionary pressures. Our hands are the descendants of pectoral fins from ancient fishies.

Currently much more work is being done with adult stem cells than with embryonic stem cells. Therefore you will get much more results from the adult cell research than the embryonic one.
It says nohing about the usefulness or morality of the research one way or another.
Actually, your point about rejection and cancer tends to point to the solution of using cloned embryonic stem cells. Which will combine the advantages of both techniques.
