The regeneration of lost body parts has just moved from science fiction to U.S. military policy.

Yesterday the Department of Defense announced the creation of the Armed Forces Institute of Regenerative Medicine, which will go by the happy acronym AFIRM. According to DOD's news service, AFIRM will "harness stem cell research and technology … to reconstruct new skin, muscles and tendons, and even ears, noses and fingers." The government is budgeting $250 million in public and private money for the project's first five years. NIH and three universities will be on the team.

If you've been following Human Nature for the past three years, you know that tissue regeneration is well underway. The military has been working on regrowing lost body parts using extracellular matrices. Scientists in labs have grown blood vessels, livers, bladders, breast implants, and meat. This year they announced the production of beating, disembodied rat hearts. At yesterday's press conference, Army Surgeon General Eric Schoomaker explained that our bodies systematically generate liver cells and bone marrow and that this ability can be redirected through "the right kind of stimulation."
