Stem cells have recently been heralded as being the key to ending a great number of the world's maladies. Stem cells' functions range from tissue repair to the formation of the entire human body. Most stem cell research presently focuses on harnessing the powers of stem cells and using their plasticity to create new cells to replace damaged ones. Once this is realized, many degenerative diseases as we know them will probably be history. However, the pessimists amongst us have long suspected that this was all too good to be true. What happens when these miracle cells stop working properly? Cancer.
