Humans Could Regenerate Tissue Like Newts By Switching Off a Single Gene

Re-growing Tissues Like Newts By shutting off a single gene, researchers think humans could regenerate damaged tissue just as newts do. J. Carmichael

“Scientists have long been stymied by human regenerative healing -- that is, wholesale re-growth of, say, a severed limb -- an ability inherent in some species but lost on humans. But new research suggests the ability to regenerate isn't based on something newts and flatworms have that we don't; rather, it's something we do have that's keeping us from regenerating tissues.”
