We may be on the path to a new technology in which quite literally, we will be growing new body parts. It's called "regenerative medicine," where cells in the human body are manipulated into regrowing tissue. Researchers have so far created beating hearts, ears and bladders. Biotech companies and the Pentagon have invested hundreds of millions of dollars in research that could profoundly change millions of lives. Dr. Anthony Atala runs the Wake Forest Institute for Regenerative Medicine in North Carolina. You name the body part, chances are Dr. Atala is trying to grow one. "The possibilities really are endless," he said. Atala says every organ in our body contains special stem cells that are unique to each body part. The key to regeneration, he says, is to isolate and then multiply those cells until there are enough to cover a mold of that particular body part. In Pittsburgh, researchers are taking a different approach: at the McGowan Institute for Regenerative Medicine they are trying to trick the body into actually repairing and regenerating itself. Dr. Steven Badylak, the institute's deputy director, [is] convinced that the key to regeneration is finding the switch in our bodies that tells our cells to grow when we are still in the womb. Badylak said. "If we could make the body or at least the part of the body that's missing or injured think that it's an early fetus again. That's game set and match."
Note: Robert Becker did amazing, pioneering research in this field over 25 years ago, yet was shunned by conservative academia. For his landmark book The Body Electric, click here.
