The New York Times reports today that European physicians have successfully transplanted a human windpipe using the recipient's own bone marrow stem cells to reline a donor trachea, thus preventing its rejection by her immune system. Using a new technique developed in Milan, physicians incubated stem cells removed from the patient's bone marrow, growing them into "a large population" which was then used to "seed" the donated windpipe. This is yet another interesting use of autologous stem cells, demonstrating their quickening pace of use in regenerative medicine.
