'We started out by taking a typical desktop inkjet cartridge. Instead of ink we use cells, which are placed in the cartridge,' said Dr. Anthony Atala, director of the institute. The device could be used to rebuild damaged or burned skin. ... Burn injuries account for 5% to 20% of combat-related injuries, according to the Armed Forces Institute of Regenerative Medicine. The skin printing project is one of several projects at Wake Forest largely funded by that institute, which is a branch of the US Department of Defense. Wake Forest will receive approximately $50 million from the Defense Department over the next five years to fund projects, including the skin-creating system. Researchers developed the skin 'bio-printer' by modifying a standard store-bought printer. One modification is the addition of a three-dimensional 'elevator' that builds on damaged tissue with fresh layers of healthy skin."
