Submission + - Scientists Demonstrate Mammalian Limb Regeneration (sciencedaily.com)

telomerewhythere writes: A quest that began over a decade ago with a chance observation has reached a milestone: the identification of a gene that may regulate regeneration in mammals. The absence of this single gene, called p21, confers a healing potential in mice long thought to have been lost through evolution and reserved for creatures like flatworms, sponges, and some species of salamander.

Researchers found mice lacking the gene p21 regrew limbs instead of creating scar tissue.
