More Like Salamanders
One vision of stem cell medicine is, as this Forbes writer puts it, "to make human beings more like salamanders. When chopped into bits, salamanders regenerate. Humans don't. By exploiting an elegant natural process -- the body's ability to heal itself with stem cells -- scientists are hoping to find therapies or cures for a long list of conditions including spinal cord paralysis, heart failure and Alzheimer's. 'Humans have a mechanism that sort of dampens down that ability. Infusions of stem cells are basically overcoming the damping-down mechanism.'" The path ahead is quite clear from a high level viewpoint, but a great deal of work remains to fill in the details and achieve goals. Fortunately, funding and public support exist - it's amazing what can be accomplished with those two things in hand.
