Towards More Human Trials
Wired takes a look at the the timeline for the next wave of human trials in stem cell based regenerative medicine: "Several scientists have used embryonic or fetal stem cells to help rodents with spinal cord injuries walk again. The researchers travel the country showing videos of rats dragging their hind legs, followed by clips of them miraculously hopping around following stem-cell injections. The question now, especially in the minds of the 250,000 people in the United States with spinal cord injuries, is: When will the research transfer into helping humans? The answer depends on who you ask. Some scientists believe it could happen as soon as the end of this year. Others say that's too soon, and data from larger animals such as dogs or monkeys is necessary before researching with humans."
