Stem-cell therapy refers to medical procedures that use stem cells—special cells that can generate new, specialized types of cells—to treat illnesses, injuries, and other medical maladies. Basically, applying stem cells to damaged or diseased body tissue might promote the healing and regrowth of that tissue. The most therapeutically useful stem cells come from human embryos, but gathering and using these are highly controversial, and most scientists opt to use less-adaptable stem cells from other sources. Experimentation with this form of medicine continues. Many medical experts believe that stem cells will play a major role in future healthcare practices. Many others downplay their effectiveness and characterize the therapy as prohibitively dangerous. |
