Stem cells are the basic kind of general-purpose cells which can turn into any other kind of cell. Once a cell becomes specialised, it may continue to divide, but it can only produce cells of the same speciality - kidney cells produce more kidney cells, skin cells produce more kidney cells etc. A newly fertilized it the original stem cell, which splits into more and more stem cells. But after a while, cells start specialising and the body forms, and once specialised the cells cannot go back. If we could extract stem cells from a patients body, we could then have the chance of growing them into any organ we wanted. No need for transplants, just grow a copy of the organ you want in a test tube. Or, more simply, insert stem cells into the part of the body which is breaking up, and they will automatically repair it by turning into the right kind of cells for the locality.
