The Department of Defense wanted to create healing putty that can be injected into broken bones on a battlefield. Dr. Steve Stice and the Regenerative Bioscience Center answered the call and have come pretty close. Through a painstaking process, they extract and genetically engineer an animal’s own stem cells to overproduce healing proteins, mix it in gel, and can inject it back into the animal as fracture putty that can accelerate healing. This has the potential for widespread use, from soldier’s skull fractures to elderly falls.
