The skin gun is no longer science fiction. A doctor has created a prototype medical device that literally sprays skin cells onto burn victims to re-grow skin.
Once grafts took weeks, but now the skin gun does the work in under two hours and the burns heal within days. It has successfully treated over a dozen patients so far.
Doctor Jörg Gerlach, of the University of Pittsburgh's McGowan Institute for Regenerative Medicine, has discovered a method which regenerates healthy skin stem cells from the victim and sprays it on the burned skin.
