Researchers have discovered a protein that stimulates bone stem cells in mice with diabetes so that the animals heal better after a fracture. They suggest that this could lead to a new treatment to improve bone repair in people with diabetes.

Bones of normal mice (top) form larger calluses during healing, which lead to stronger repair. However, bones of diabetic mice (bottom) have smaller calluses, which lead to more brittle healed bones.
