Narrator: This is Science Today. New research has found that applying insulin directly to skin wounds significantly sped up wound healing. Insulin is a hormone known primarily for regulating sugar levels in the blood, so study leader Manuela Martins-Green, a professor of cell biology at the University of California, Riverside says this research has potential for diabetics.
Martins-Green: It could have an effect on the physiology because if some of this insulin is absorbed to the body, then of course it's going to have an effect on their physiology. We really don't know how it's working precisely. We know it's affecting this type of cell and that type of cell, but we really haven't put it together and that's what we're doing now.
Narrator: Martins-Green cautions this research is experimental.
Martins-Green: We have only tried it in animals and so it would be great if we could try it in people with very controlled protocols, but this is not something that someone could just decide to do on their own.
