Prospects for organ and tissue replacement

Abstract

Damage or loss of a tissue or organ is common, costly, and tragic. Advances in mechanical artificial organs and organ transplantation have improved the treatment of organ failure, and advances in molecular immunology, tissue engineering, and stem cell biology offer the promise of even better therapeutic modalities for treating organ failure in the future. Enhancement of immune tolerance of transplanted tissues, improved understanding of cellular differentiation and tissue development, and advances in biomaterials may enable the de novo creation of implantable tissue and organs for transplantation. Innovative techniques for prevention and treatment of tissue loss and organ failure should improve the quality and length of life.
