Non-Embryonic Stem Cells Developed From Skin Cells
juliangamble writes "Scientists reported Thursday they had developed a technique that can quickly create safe alternatives to human embryonic stem cells, a major advance toward developing a less controversial approach for treating a host of medical problems. The researchers published a series of experiments showing they can use laboratory-made versions of naturally occurring biological signals to quickly convert ordinary skin cells into cells that appear virtually identical to embryonic stem cells. Moreover, the same strategy can then coax those cells to morph into specific tissues that would be a perfect match for transplantation into patients."
To quote the article:
Here we describe a simple, nonintegrating strategy for reprogramming cell fate based on administration of synthetic mRNA modified to overcome innate antiviral responses. We show that this approach can reprogram multiple human cell types to pluripotency with efficiencies that greatly surpass established protocols.
I repeat, 'GREATLY SURPASS ESTABLISHED PROTOCOLS.'
Better = Better
I think you're right about the former, but why does that matter now? Here we are with an alternative that's better in an absolute sense (even if not in a time relative sense) than embryonic stem cells. So why not go with that and continue to improve the technology? Do we need to go back to destroying embryos to develop an inferior product?
Also, I'm not wholly convinced that it is just a matter of state-of-the-art improvement where embryonic stem cell research had left off. I think the restriction certainly catapulted this type of research, but there are still over a dozen lines of embryonic stem cells (which can still be infinitely reproduced) that were being worked on, but they did not get to this point.
If we had Embryonic stem cells say from Cord blood or some other conflict free source.
Would the biological signals work the same on them to become muscle, nerve or organ replacement tissue?
I wonder though, if they don't find a way to lengthen the telomere tail on the cell's dna, it's age won't be reset. You can't just take anyone's skin cells and make stem cells from them, if they're older generation cells the telomere tail will be short and the cell culture's lifespan will also be short.

History likewise shows numerous examples of people dieing. This doesn't mean that tacos often kill.
That's a non sequitur.
Otherwise, we're just bandying about our opinions, aren't we?
Humans have rights not because of the genetic codes in our cells but because of our individual experience, potential and the investiture of others.
I see where you're going, logically, but legally speaking you're not correct. Intercourse with a human corpse is one example. Cannibalism is another. Abortion is yet a third, though to an agreeably less distinct sense.
Material from humans has a greater value than other flesh and bones normally would. That's a simple fact.
Reproductive material that might produce a viable human, even more so - and understandably so.
