Silk and ceramics offer hope for long-term repair of joint injuries

17 septiembre 2015

Driven by the need to develop more effective therapies requiring less recovery time for common joint conditions such as osteoarthritis, an international team of researchers has developed an integrated two-part scaffold for implantation into damaged joints — with cartilage scaffold made from silk, and bone scaffold made from ceramics. This combination of materials allows stem cells to successfully populate the graft and differentiate into cartilage and bone cells. The cells fill the damaged areas to reconstitute the original structure of the joint, after which the scaffold biodegrades, leaving the smooth surface required for a pain-free, functioning interface.
