...nearly a decade in the making, but the first human trial using embryonic stem cells was approved on Friday...
...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...
...trial will enroll patients with injury to the thoracic region, high in the spinal cord between the third and 10th vertebrae. Doctors will be trained to inject the cell treatment at specific locations, where the cells will remain to do their nerve-nurturing work. "I think it's incredibly exciting," says Dr. Susan Fisher, a stem-cell scientist and a professor of obstetrics, gynecology and reproductive science at University of California, San Francisco. "This really provides a blueprint for how to do these sorts of trials. It really proves the principle that these sorts of human embryonic-stem-cell therapies...
...that process wasn't such an easy hurdle to overcome. 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...
...Bush Administration resisted, preferring to fold the currency issue into the broader biannual "strategic economic dialogue" (SED) started by former Treasury Secretary Hank Paulson. That less confrontational setting was more likely to produce results on the currency issue than any forum that smacked of the U.S. putting Beijing on trial for "manipulation," the Bushies believed. In fact, over the past two years, the RMB did rise nearly 20% against the dollar. (Read "China's Trade Slump Worsens in December...
