The group calls for the retraction of six publications by surgeon Paolo Macchiarini regarding the synthetic trachea transplantations that led to the death of at least three patients. 

An independent investigator says that the surgeon misrepresented the truth in papers about artificial trachea transplants.

An investigation has found the thoracic surgeon who transplanted artificial tracheae into patients not guilty of overhyping his research.

Five years after receiving a tissue-engineered airway, the 30-year-old Colombian patient is doing well, having experienced no immunological complications associated with the procedure.

After receiving a bioengineered windpipe, which was seeded with her own stem cells, the 2-year-old has succumbed to complications from a recent surgery.

Doctors culture a custom-made trachea from plastic fibers and human cells, and successfully implant it into a child who was born without the organ.

To cope with a growing shortage of hearts, livers, and lungs suitable for transplant, some scientists are genetically engineering pigs, while others are growing organs in the lab.
