Scientists Synthesize Jawbones From Pig Fat

From stresses imposed during mastication to facial expressions associated with speech production, the temporomandibular joint (TMJ) is one of the most load-bearing organs in the human body. It’s intricacies and unique curved shape pose challenges to recreate from bone grafts.

In a paper published in Science Translational Medicine this month, researchers at Columbia University managed to grow replacement jawbones, along with their joints….from the stem cells of pigs!
