BehindTheMedspeak: "Functioning Anal Sphincter Grown in a Petri Dish"



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.

Some lucky a**hole could probably get a couple thousand for that a**hole on ebay.

You never know when you might require a spare sphincter!
