Last week, the FDA gave biotech firm Geron the green light to proceed with clinical trials of an embryonic stem cell treatment for spinal cord injuries. But while we wait on promising embryonic stem cell research to clear political and regulatory hurdles, adult stem cell research is trucking right along. Yesterday it was announced that Iraq War veteran and Marine Matt Cole, paralyzed from the chest down since a 2005 insurgent attack in Iraq, has enrolled as the first patient in the first FDA clinical trial of adult stem cells used to treat spinal cord injuries.
