Bio-artificial trachea made in Iran
Iranian doctors have carried out an in situ transplant of bio-artificial trachea in humans for the first time in the world. A team of tissue-engineering scientists at the Lung and Tuberculosis Center at Tehran's Shahid Beheshti University of Medical Sciences and Health Services carried out the transplant on a 29-year-old woman who had lost her trachea in a car accident two years ago. The researchers used bio artificial materials instead of stem cells and injected them directly into the trachea to make a good architecture of the organ.
