Autotomy and Tissue Regeneration
At least two species of African spiny mice, Acomys kempi and Acomys percivali, are capable of autotomic release of skin, e.g. upon being captured by a predator. They are the first mammals known to do so. They can completely regenerate the autotomically released or otherwise damaged skin tissue - regrowing hair follicles, skin, sweat glands, fur and cartilage with little or no scarring. It is believed that the corresponding regeneration genes could also function in humans.

Famous quotes containing the words tissue and/or regeneration:
“Whether or not his newspaper and a set of senses reduced to five are the main sources of the so-called “real life” of the so- called average man, one thing is fortunately certain: namely, that the average man himself is but a piece of fiction, a tissue of statistics.”
—Vladimir Nabokov (1899–1977)
“Typically, the hero of the fairy tale achieves a domestic, microcosmic triumph, and the hero of myth a world-historical, macrocosmic triumph. Whereas the former—the youngest or despised child who becomes the master of extraordinary powers—prevails over his personal oppressors, the latter brings back from his adventure the means for the regeneration of his society as a whole.”
—Joseph Campbell (1904–1987)
