Scientists Synthesize Jawbones From Pig Fat (archive)
In patients with congenital defects or who have suffered accidental injuries, the jawbone is nearly impossible to replace. Curved and complex, the bone ends with a joint covered with a layer of cartilage. Both parts must withstand enormous pressures as people chew.
"It is one of the most loaded bones in the human body," said Gordana Vunjak-Novakovic, a professor of biomedical engineering, medicine and dental medicine at Columbia University in New York.
In a paper published in Science Translational Medicine [DOI: 10.1126/scitranslmed.abb6683] [DX] on Wednesday, she and her colleagues reported a surprising success: They managed to grow replacement bones, along with their joints, from the stem cells of pigs. A clinical trial will soon begin in patients with severe birth defects.
The researchers say they hope the same sort of technique can someday be used to grow other replacement bones and joints, including knees. Even if the strategy works, however, it will be years before those who need new jawbones or joints can have them engineered from their own cells.
