Facial and cranial bone may soon be regenerated with scaffolding that can be injected in liquid form to harden and then be removed once again as a liquid, according to this article. The temperature-sensitive gel developed at Rice University "leverages injectable, thermally responsive, chemically cross-linkable and bioresorbable hydrogels for regenerative medicine applications," says bioengineer Antonios Mikos. "It enables the formation of scaffolds locally and the delivery of growth factors and stem cells into defects of complex anatomical shapes with minimal surgical intervention."
