Woman gets first trachea transplant without drugs

A Colombian woman has received the world's first tailor-made trachea transplant, grown by seeding a donor organ with her own stem cells to prevent her body rejecting it, an international research team reported on Wednesday.
The success of the operation, performed in June using tissue generated from the woman's own bone marrow, raises the prospect that transplanting other organs may be possible without drugs to dampen the immune system, they said.
