Researchers are developing a specialized skin "printing" system that could be used in the future to treat soldiers wounded on the battlefield.
Scientists at the Wake Forest Institute for Regenerative Medicine were inspired by standard inkjet printers found in many home offices.
"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.
