Abstract

The surgical transplantation of kidney and other organs to patients from human donors (homografts) and non-human primates (heterografts), has aroused great scientific interest as well as sensational publicity. The procedure is still in the experimental stage, and permanent survival of the graft can be expected only in transplantation between identical twins: there have been some survivals for one year or more in cases other than identical twins, and one patient is alive after three years.
