This new study sets the stage for improved treatments for bone diseases and injuries, and demonstrates a valuable new research tool. Cartilage is a fascinating substance. It coats the ends of our bones, allowing them to glide by one another at joints like our elbows and our knees. The surface it creates is about five...
