Replacing Skin Grafts With Autologous Stem Cells

From the MIT Technology Review: "Traditionally, treatment for severe second-degree burns consists of adding insult to injury: cutting a swath of skin from another site on the same patient in order to graft it over the burn. The process works, but causes more pain for the burn victim and doubles the area in need of healing. Now a relatively new technology has the potential to heal burns in a way that's much less invasive than skin grafts. With just a small skin biopsy and a ready-made kit, surgeons can create a suspension of the skin's basal cells - the stem cells of the epidermis - and spray the solution directly onto the burn with results comparable to those from skin grafts. ... 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 the 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."
