The first fully lab-grown organ transplant has taken place

you are correct, "they" are the British and the swedes. If the ban was not around, it would be American doctors and scientists doing it first.

likely without the US ban on federal funds for embryonic stem cells they wouldn't have been able to do this. :hmm:

Not really. Embryonic stem cell research is one of the basic building blocks leading to this type of advancement.

Another big likely though: if they had said "a man's trachea was cloned from his own cells..." then half of the population of the U.S. would have said "I don't care, cloning is bad, mmkay."

no, not necessarily as science doesn't have boarders. but the US ban on federal funds being used for embryonic stem cells forced the advance of other sources of stem cells, such as a person's own.

ahh but you are assuming that research on embryonic stem cells would not have furthered the knowledge base beyond what we could have otherwise done.

Well then you're playing god - and besides, the new cloned trachea wouldn't have a soul, so it's an abomination before god.
:awe:

those were adult stem cells, dude. They didn't take them from his own, uh embryo.

the US has never had a problem with adult stem cell research. But convince some neolithic pus-brained moral police that embryo = sacred cute little baby, you get a shit storm.

soon, soon enough, these fuckwads will take their ancient morality and fear of science somewhere far away from the rest of the free-thinking and progressive world...maybe to Kansas?

Actually embryology would be important here. To build the scaffold, you would need to know how the trachea forms. If you need to study which genes to induce, you're not going to want to do that on a human. A better way to study that would be to look at rats first because it's cheaper and you only have to worry about PETA protesting. I'm not saying it's not important to study stem cells, but somethings are more practical on lab animals rather than humans. Once you can do it for rats, you start using human stem cells. We don't need humans for every study.
 
TWO DAYS? I dunno, something isn't clearly explained here. Think about how long it takes the body to fully form and grow.....to go from pure cells and develop an entire trachea based on a matrix in the shape of a trachea in 48 hours is insane. I took a tissue engineering course about 3 years ago, and unless something radically changed in the field, then I'm just completely baffled how they got stem cells (I'm assuming these are adult stem cells) to follow the entire cascade of signals back and forth, and divide, multiply, and specialize enough, with all the right types of chemical, electrical, and mechanical stimulus to create an entire trachea.

If true, then this is just crazy...


edit:
After reading the original article on the guardian this seems to be an experimental procedure - they put in a trachea shaped scaffolding SEEDED with stem cells. Who knows if these stem cells will truly differentiate through the right pathways to create a true new trachea. This is faaaaaaarrr from conclusive, and is just more journalism to grossly exaggerate what is going on - organ transplant this is not. More like "patient receives implant of building blocks that might regenerate lost trachea and turn into an organ, we aren't sure yet...and we sure as hell hope this isn't going to turn cancerous"
