THE STEM CELL DEBATE: IS IT OVER? New breakthroughs may soon bring this debate to an end. Scientists have larned how to stimulate a patient's own cells to behave like embryonic stem cells. These so-called induced pluripotent stem (iPS) cells are reducing the need for human embryos in research and opening up exciting new possibilities for stem cell therapies.
Where Do Stem Cells Come From?: Stem cells, artistic rendering. The type of cells used in stem cell transplants for cancer patients come from a living donor. Not to be confused with embryonic stem cells, which are obtained by destroying a human embryo.
