Marty Graham reports for Wired:
While the use of stem cells harvested from human embryos has been getting the most media attention, scientists and doctors have also been working with adult stem cells that also have the ability to become one with their environment and to replicate as cells of their adopted tissue. Using adult stem cells — grown inside the body or in the lab — has become accepted in the veterinary community, and horses have benefited greatly. Researchers are working to bring those same benefits to humans, but there are still hurdles left to clear.
