Novel Cell Therapy to Patch Damaged Heart

Scientists at Columbia University have discovered a new method to patch a damaged heart using a tissue-engineering platform that enables heart tissue to repair itself. In the study, the team removed the cells of a human heart muscle but left a protein scaffold with intact architecture and mechanical properties. They filled the scaffold with stem cells and then applied the patches (human repair cells) to the damaged heart tissue. The patches promoted the growth of new blood vessels and released proteins that stimulated the native tissue to repair itself.
