...trial, which will test a stem-cell-based treatment for spinal-cord injury, will begin later this summer and will use cells generated by Geron Corp. The approval marks the first time human stem cells, extracted and grown from embryos, will be transplanted into patients. Adult stem cells, which are present in many types of tissue, have been used in treatments for years - the most common being bone-marrow transplants in cancer care - but an embryonic study is a whole new thing. There's a good reason it's being greeted with so much excitement. (See the top 10 medical...
...Because no one has used embryonic stem cells or the cells derived from them in people before, the FDA was particularly cautious. The trial that it approved is what's known as a Phase 1. It will involve no more than a dozen patients and is not designed to test the effectiveness of the cells. Rather, it will simply monitor the safety of inserting them into people. The researchers will be looking for whether the cells cause tumors, trigger an immune response or start to migrate away from the spinal-cord area. "There are certainly unknowns that...
