Stem cells are fundamental to biology. In the course of embryonic development, stem cells generate all the specialized cells that populate body tissues like muscle, the nervous system, and blood. In adults, reserves of stem cells repair and regenerate tissues damaged by disease and wounding. Because of the potential of stem cells to generate fresh, healthy cells, there is a huge interest in cultivating them to treat various diseases. This year's Holiday...
