Skin-grafting is a life-saving procedure for people with large area skin wounds caused by burns or trauma. Conventional autologous (self) skin grafting techniques require the creation of large donor site wounds, causing numerous complications including pain, infection, blistering, discoloration, and scarring. Based on previous research, many of these adverse effects can be improved, or even eliminated, by harvesting skin tissue in very small biopsies. These "micro-biopsies" are less than the size of a sewing pin. Then, they are put back together into a skin graft.
