Stem cells used in trachea transplant

Doctors have successfully used stem cells in a rejection-free transplant of a trachea.

This is a great example of internationalism in science – the patient was Colombian, the hospital in Barcelona, stem cells cultivated in Bristol and the final stage of the windpipe construction completed in Milan.

Check your understanding:

Did they grow a new trachea from scratch?

How did they prevent rejection of the tissue?

There is a good short reader on the NewScientist website.

The original research paper was published by The Lancet.

And another video on National Geographic.
