Researchers tout progress with 'skin printers,' hope to one day treat battlefield wounds

We've already seen that living tissue can be printed using what amounts to a bio-inkjet printer, and some researchers from the Wake Forest Institute for Regenerative Medicine now say they've made some considerable progress that could bring the technology one step closer to use on the battlefield. Specifically, they've been able to speed up the healing of wounds on mice using a "printed" swath of tissue and completely heal the wound in three weeks, whereas an untreated wound did not heal itself in the same time period. Of course, there's no word on any plans for tests on humans just yet, but the researchers do plan to take one more step in that direction by moving on to tests on pigs next.
