Narrator: This is Science Today. A research team at the University of California, Riverside is trying to understand the cellular and molecular mechanisms of normal wound healing. Manuela Martins-Green, a professor of cell biology, is leading this research effort.
Martins-Green: In my laboratory, we have three major branches of research. One concentrates on trying to understand the cell and molecular mechanisms of normal healing, so that we can then be better informed to try to help people that don't heal well. To try to solve the impaired healing. Another branch of research devotes itself to finding molecules to improve healing. And the third is to look at how they impair wound healing.
Narrator: In lab rats, Martins-Green discovered that applying insulin directly to wounds dramatically sped up the healing process, but this has not yet been applied in humans.
Martins-Green: It's promising. We're trying to do
our best to accelerate these studies as quickly as possible.
