First successful 3D-printed biologic tracheal graft in an animal model

Mount Sinai: A team of researchers from Icahn School of Medicine have combined 3D printing technology with human stem cells to create the first successful 3D-printed biologic tracheal graft in an animal model. Using a biocompatible polymer, researchers created a customized 3D-printed tracheal graft seeded with stem cells. The graft was then used to repair a defect in an animal. The Mount Sinai team continues to work toward creating a customized tracheal graft that could be used to repair complex airway defects in humans.
