Doctors Grow Pig Teeth in Rat Intestines

Now That's Just Disgusting!

Yahoo! News | Doctors Grow Pig Teeth in Rat Intestines: "BOSTON (Reuters) - U.S. doctors have managed to grow pig teeth in rat intestines, a feat of bioengineering they said could spark a dental revolution."

Who says those laboratory rats are worth nothing? I wonder how they get the teeth out: by natural means or by some other way? Kinda makes me want to floss so that I can keep my own teeth awhile longer...
