Hello Professor and Class, In 2011, the first artificial trachea was successfully transplanted in a patient with end-stage thracheal cancer. The doctors used a donor’s cartilage scaffold and took the patient’s stem cells from his own bone marrow to grow the trachea (Melnik, 2011). Another successful transplant I found in my research came from doctors in New England. They grew and implanted a “nerve bridge” for a man that had a spinal column. The implant is almost 2 years old and the man is said to have regain partial movement and feeling. From what I found there are a lot of organs being grown either by 3D printing or through stem cells that are taken from a patient’s bone marrow. A professor in the UK grew a functioning Thymus, however,
