Wet wound healing: from laboratory to patients to gene therapy

Wet treatment of wounds has been used as an "irrigation" method since the seventh century. We have developed the concept of an in vivo tissue culture that facilitates wound healing and allows tissue engineering. A transparent, flexible, round chamber provides the wet environment. This system heals clean wounds as fast or faster than any other method, with less scarring. It allows delivery of analgesics, antibiotics, growth factors, growth media, and cells into the chamber, becoming a platform for tissue engineering. Gene therapy of the wound can be done in the chamber with growth factor and other genes. A tetracycline switch allows precise timing and amounts of expression and provides the opportunity for sequential expression of genes delivered at the same time.
