Regenerative Medicine Helps Rebuild Wounded Warriors

Cutting Edge Treatments Heal Wounds of War

While AFIRM pushes the limits of regenerative medicine, other programs like Operation Mend, which helps burned and disfigured service members get ground-breaking reconstructive surgery, aim to improve veterans' access to cutting-edge care.

"We've had 86 patients come through the program, with over 250 operations," said Dr. Christopher Crisera, associate professor of plastic and reconstructive surgery at Ronald Reagan UCLA Medical Center and medical co-director of Operation Mend.

Mike Mills was one such service member. The Army staff sergeant suffered third-degree burns to almost a third of his body when an IED detonated next to his vehicle in Iraq.

"I was missing half my left ear, and my nose was pretty much gone," said Mills, 47, who also lost two fingers and shattered multiple bones. "I was content with how I looked without the nose. But I don't like people staring at me, so I was becoming a bit withdrawn."

Through Operation Mend, Mills had surgery to reconstruct his nose using tissue from his forehead.

"Now that I have the nose, I don't get as many stares," said Mills, adding that he would never have been able to afford the surgery without Operation Mend's help.

"It's normal when you're burned or disfigured to be self-conscious," said Crisera, explaining how "form and function" go hand in hand. "If you can restore some normalcy to the form, you can restore their self-confidence. That's one of the most gratifying things about the program."

Mills still gets some stares because of his ear. But researchers at Massachusetts General Hospital may one day fix that, too. They've created a living ear replica by seeding sheep cartilage cells on an ear-shaped scaffold.

"The scaffold is special because it's made of collagen, which is the component of your skin that makes it stretchy, and a metal framework that helps maintain the shape," said Cathryn Sundback, co-director of the Boston-based hospital's Laboratory for Tissue Engineering and Organ Fabrication.

The stand-in thrived when it was implanted onto sheep. The next step will be clinical trials that would use patients own cartilage cells, borrowed from the septum of the nose or the ribs, to grow replacement ears.

"I'd like to think we're going to make a big difference, particularly in the area of recreating injured war fighters' faces," said Sundback.

For Strang and Mills, the science that's helping them and their fellow service members rebuild their broken bodies sounds more like science fiction.

"It's really amazing that you can take stuff and make bones and muscle, grow ears and organs," said Strang, adding that he's glad scientists have his back. "It definitely makes me happy that they're looking out for us in that way. And they're just getting started. There's so much more they can do."
