Transplantation and its biology: from fantasy to routine

Abstract

The replacement of diseased organs and tissues by the healthy ones of others has been a unique milestone in modern medicine. For centuries, transplantation remained a theme of fantasy in literature and the arts. Within the past five decades, however, it has developed from a few isolated attempts to salvage occasional individuals with end-stage organ failure to a routine treatment for many patients. In parallel with the progressive improvements in clinical results has come an explosion in immunology, transplantation biology, immunogenetics, cell and molecular biology, pharmacology, and other relevant biosciences, with knowledge burgeoning at a rate not dreamed of by the original pioneers. Indeed, there have been few other instances in modern medicine in which so many scientific disciplines have contributed in concert toward understanding and treating such a complex clinical problem as the failure of vital organs. The field has been a dramatic example of evolution from an imagined process to an accepted form of therapy.
