The potential benefits of stem cell therapy have been widely discussed for decades. Potential benefits include reduction of the pain of arthritis and help patients heal faster after surgery. But stem cell therapies can be prohibitively expensive. At the projected costs, these potential life-changing treatments would be far out of range of the vast majority of those who need them. But thanks to Carnegie Mellon University’s Kris Dahl, PhD, professor of chemical engineering, and Veronica Hinman, PhD, head of CMU’s Department of Biological Sciences, stem cell therapy could get a lot less expensive. And the key to this approach lies in the incredible regenerative powers of starfish.
