Scientists today are able to artificially grow organs and use them for transplants. The next step in the process is to find a way to help old and damaged organs rebuild themselves. Scientists in Britain seem to have found a way to make this happen. By injecting stem cells into elderly mice, researchers were able to repair an organ called the thymus. Clearly this is all in it's infancy, but if this works out it, could mean that humans would be able to live much longer than they currently do. Can you imagine being able to repair hearts, lungs, kidneys, and any other organ without surgery or transplants? Now that would be amazing.
