Summary:
Stem cells often are heralded as having infinite curative possibilities. But a growing field of research suggests that some stem cells turn bad. And when they do, they can be hard to kill. Normal stem cells divide into one identical stem cell and a second that is an organ or tissue cell, say for the blood, skin or kidney. Cancer stem cells work the same way as normal stem cells, but with a deadly twist. When a cancer stem cell divides, one becomes an identical cancer stem cell, while the other becomes a tumor cell.
