This is the amazing story of how stem cell reaearch has led to a Colombian woman having replacement parts fitted that are a match for her own genes because they were grown from them! Imagine in a few years time what other parts of the body we could replace in this way. How about a new kidney, liver or lungs? Fancy a new brain? Would you be the same person if you had a new set of parts fitted? Throws up some interesting moral dilemmas.
