Missing teeth, broken bones on the battlefield or a bad slip on the job — the University of Iowa is working on making all your worries go away.

Recent successes in the lab with bone regeneration, using what is known as bio patches, are poised to change the medical landscape in the years to come.

A collagen “scaffold” seeded with self-replicating DNA molecules for producing bone showed “significant bone regeneration and growth in animal lab testing,” according to the defense website Military.com.

“We delivered the DNA to the cells, so that the cells produce the protein and that’s how the protein is generated to enhance bone regeneration,” said Aliasger Salem on a University of Iowa Web page.

Although the research is still in its early stages, scientists believe that implications for wounded troops, first responders and the field of dentistry are promising.

“I would argue that anything done in a clinic is better, because it’s a sterile environment, there are doctors to perform it,” Salem Elangovan, assistant professor at the university’s College of Dentistry, told Military​.com. “But if you have an exposed wound and bone fracture, I could imagine this would be a step taken as part of the initial treatment.”
