Washington: A bioengineered stem cell-based trachea, composed of both artificial and biological material, has been successfully transplanted.Surgeon Paolo Macchiarini who conducted the transplant is now planning to use the technique to recreate more complex tissues, such as the oesophagus and diaphragm or organs such as the heart and lungs.He has also made an experimental attempt to regenerate brain in mice and rats.In June 2011, media all over the world reported about a ground breaking transplant, where a patient received an artificial trachea covered in his own stem cells. The result was an artificial windpipe with biological functions. To date, five operations have been carried out using this technique."We learn something from each operation. This means we can develop and refine the technique. We are also evaluating how we can transfer our experiences to other fields, such as neurology. The aim is to make as much use of the body`s own healing potential as we can", said Macchiarini, Professor of Regenerative Surgery at Karolinska Institutet, and responsible for the surgery.
