Tissue Transplantation 1597 – Rebuilding the Soul and Body

In 1597, Italian surgeon Gaspare Tagliacozzi wrote: "We bring together, rebuild, and create all the parts of the face given at creation or taken away by fate, not merely for appearance but also to build the spirit and help the soul of the affected person." Like several ancient Indian surgeons before him, Tagliacozzi tried to create an artificial nose, marking an intriguing milestone in the history of skin transplantation. These operations were surgical procedures to transplant tissue to replace tissue lost through burns and injuries. Tagliacozzi partially cut a skin flap from the patient's arm and stitched it to the area of the missing nose. For more than a week, the patient's arm was also secured to the face with a strap. After healing, the flap was detached from the arm and the new nose was shaped as desired.

In 1869, Swiss surgeon Jacques-Louis Reverdin used tiny pieces of skin completely detached from one part of the body as "seeds" where skin was missing. Skin gradually grew and spread from these tiny grafts. In 1874, German surgeon Carl Thiersch published a paper describing a skin transplantation method using a very thin slice of epidermis (the outer skin layer) and underlying dermis (the skin layer between the epidermis and subcutaneous tissues).

British surgeon Peter Medawar conducted pioneering research showing that skin grafts were more successful when the donor was a close family member of the recipient. For example, skin from a sibling is more useful than skin from a more distant relative. In the early 1950s, however, he injected tissue cells from unrelated adult mice into mouse embryos and discovered that, once born, the mice could accept skin grafts from the donor mice. He thus discovered how to modify embryos' immune systems so that donor tissue would not be rejected as foreign.
