Stem cell trachea used to save woman’s lung

AN artificial airway created from stem cells has been used to save a woman’s left lung in a landmark operation that could change the face of transplant surgery.

Mother-of-two Claudia Castillo, 30, is the first person in the world to be given a whole laboratory-engineered organ.

She is also believed to be the first transplant patient not to need powerful drugs to subdue the immune system.
