From USA Today:
In an upcoming report in the journal Gastroenterology, researchers relate that they have successfully mixed human muscle cells with mouse nerves, and then grown them on a circular mold to make replacement sphincter rings.
After implanting the lab-grown circles into eight mice, the new structures were successfully colonized by blood vessels and performed their intended function, says the study.
"In essence, we have built a replacement sphincter that we hope can one day benefit human patients. This is the first bioengineered sphincter made with both muscle and nerve cells, making it 'pre-wired' for placement in the body," said senior author Khalil Bitar of Wake Forest Baptist Medical Center's Institute for Regenerative Medicine.
This is not growing skin from stem cells which is not to say that is not cool and important, this is bioengineering a body part when it is needed. It is plug and play with this stuff. It can be made from the host's own tissue and it will not be rejected. I think it will be a plausible option in ten years. In twenty years it will be eyes and heart valves and a new pancreas that works great. The drug companies will have to shift to this stuff and they are heading that way. That will slow progress down once the technology is at our fingertips. The morons that run corporations would rather be filthy rich during their tenure instead of helping people and making their company thrive for a century. Check out General Motors, Enron or Carter Medicine Company.
Bio-engineering does not mean anti-God zombies will be running around. It is nothing more than selective breeding of plants of the 1900's. Dog breeding is a good example of the dangers of ignorant people trying to make money. Good stuff comes from decent hardworking thinkers and none of it should be restricted or delayed.
