The changed face of skin grafts
For many years, scientists have been harnessing the regenerative capabilities of human skin to treat victims of severe burns using skin transplants. Skin transplants are possible because of the existence of stem cells located just under the top layer of skin. Every day, thousands of new skin cells are produced to replace those that have been shed. When someone suffers severe burns that destroy the source of these stem cells, their skin can no longer regenerate on its own.
