First Fully Lab-Grown Organ Successfully Transplanted

ADAM MARTIN10:31 AM ET22,731 ViewsComments (4)
A man who developed cancer in his windpipe has gotten a new trachea, grown entirely from his own stem cells over two days in a laboratory in Sweden. The operation is remarkable because it's the first time a completely synthetically grown organ has been transplanted into a patient, The Guardian reported. "The synthetic trachea was created by growing the patient's own stem cells on an artificial 'scaffold', which British scientists helped design. Windpipes have been grown from stem cells before, but only using the collagen 'skeletons' of donated tracheas ... Professor Paolo Macchiarini, an Italian expert in regenerative medicine who led the groundbreaking operation, designed the Y-shaped synthetic trachea scaffold with Professor Alexander Seifalian, from University College London." The success of the operation means that patients who need organ transplants could conceivably be able to have them specially grown instead of having to wait for a donor.


Sweet. I can't wait to live forever. :D

I wonder if it's OK to smoke now, because they could almost surely replace your lungs within a few decades.

this is cool; however, more with the artificial replacements and less with growing real one.

cybernetics for the win.

They are both competing emergering technologies. It'll be interesting to see what wins out one or two decades from now, or if it's something else entirely.

Another victory for non-embryonic stem cells. What does this make the score now?

I think the real score is "who cares vs. I don't give a rats ***". But I may be mistaken.

Considering that several of the states with the most biomedical research going on have banned embryonic stem cell research, I'm going to have to go with Poor Comparisons for $800, Alex.

Original Guardian Article wrote:
Since the organ was built from cells originating from the patient, there was no risk of it being rejected by his immune system.


I think this is the worth noting. An organ grown from embryonic stem cells would still have the risk of rejection. I'm not sure about cybernetic organs (other than it's a disadvantage in GURPS)

I know this was meant mostly in jest, but the one organ you can't so easily replace with a grown replacement is your brain.

My guess is that they both will. That is, in the long run, they won't be competing technologies, but cooperative. I also think that at some point we'll wind up using genetically modified bacteria to "cheat" our way down to the nanotech scale. Why spend an enormous amount of R&D on creating a tiny, programmable, self-reproducing molecular factory when nature has already provided one?...

It's not meant to hold up to a strict comparison. It's meant as a "told you so" rebuttal to the cries of "But we need embryonic stem cell research because adult stem cells can't do the stuff we need!" when we were banning them.

and Coro's point was its too early to say "I told you so" You don't know what would be accomplished with embryonic stem cells.

Can someone remind me again what the scientific justification was for having embryonic stem cell research banned?

What? Beyond creating organs from scratch that match a patient?

What else do you want?

I believe one of the hopes with embryonic stem cells was the creation of nerve related cells, which in general don't heal.

Because it kills babies.

It uses embryos that are in many cases going to be destroyed anyway. (leftovers from artificial insemination for example) but hey, if you want to call it baby-killing .....

Well, I call artificial insemination "playing God" to begin with, so... ;)

My understanding was that all that was banned was federal funding and the creation of extra embryos for research purposes, but I could be wrong.

If god didn't want us to do it, he wouldn't have allowed us the knowledge of it.

The science they are using for the currently adult stem cells stems from the original research from embryotic ones. While the adult stem cell research grew beyond the original research, the embryotic ones stagnated due to regulation.

While the adult stuff are great, they are limited to the type of tissues they have already been programed into. The embryotic ones however, do not yet have such restrictions. The adult is also limited by their owner's supply of these cells, while the embroytic are not.

It is actually a shame that the research on embryotic have stopped as science tend to have a way of eventually making synthetic cells if the research was given a chance to mature. e.g. insulin. However at this rate, we'll never know.
