Bandage to rebuild broken bone
Researchers at King’s College London, UK, have developed a material that allows transplantation of bone-forming stem cells into severe bone fractures to speed up up the healing process.
Their work, published today in Nature Materials, describes stem cells and mature bone cells grown on a protein coated biomaterial (a three-dimensional Wnt-induced osteogenic tissue model), in a structure that simulates parts of the healthy bone. The treatment could reduce complications and infections.
Designed to specifically target the fracture the bandages can be made biodegradable to be absorbed by the body when healing has finished. The Habib group at King’s will be taking the bone-bandages into clinical trials and aims to develop the idea of the bandages concept further to improve healing in other organs and tissues.
