The MIT Technology Review has an interesting story on a new treatment for second-degree burns. According to the article:
After removing a small swatch of skin near the burn site (the closer the biopsy, the better for precise matching of color and texture), the surgeon places it in [a ready-made kit's] tiny incubator along with an enzyme solution. The enzyme loosens the critical cells at the skin's dermal-epidermal junction, and the surgeon harvests them by scraping them off the epidermal and dermal layers and suspending them in solution. The resulting mixture is then sprayed onto the wound, repopulating the burn site with basal cells from the biopsy site.
