Surgeons in Spain carried out the world's first tissue-engineered whole organ transplant in June 2008 - using a windpipe made with the patient's own stem cells.
The groundbreaking technology also means that tissue transplants can be carried out without the need for anti-rejection drugs. Five months later the patient, 30-year-old mother-of-two Claudia Castillo, was in perfect health.
She needed the transplant to save a lung after contracting tuberculosis. Her airways had been damaged by the disease. Scientists from Bristol helped grow the cells for the transplant and the European team believes such tailor-made organs could become the norm.
