Scientists unveil a possible new way of healing wounds in the future

Researchers expect the technology to be approved for human trials within a year.

— -- Scientists at Ohio State University have developed a new method that has the capability of changing the body's existing cells into new cells to promote healing.

The method, called Tissue Nanotransfection (TNT), reprograms cells through a device that uses nanotechnology. The way it would work: First, doctors would apply a light electrical stimulation to the surface of the skin. They would then place a small chip about the size of a cuff link onto the site of the wound.

In less than a second, this chip would deliver reprogramming factors (pre-programmed DNA or RNA) non-invasively into living skin cells via a high-intensity, focused electric field, converting them into whatever type of cells a scientist or doctor may choose.

This technique has previously been tested in mouse models to salvage dead tissue and promote limb re-growth. TNT is different from previous technologies in that it is a benign, instantaneous and dose-controlled re-programming factor delivery method at the single cell level.
