The African spiny mice were able to regenerate the lost ear tissue, growing new skin, hair follicles, fat cells, muscle and cartilage instead of forming scars. Pro-regenerative ECM in the African spiny mouse (Acomys) will be compared to scarring ECM in the ordinary mouse (Mus), as well as different model systems of regeneration and fibrosis. Skin shedding and tissue regeneration in African spiny mice (Acomys). Spiny … After skin loss, rapid wound contraction was followed by hair follicle regeneration in dorsal skin wounds. In this Primer article, we review these regenerative abilities, highlighting the phylogenetic position of the spiny mouse … The African spiny mouse is the only mammal known to science that is capable of regrowing its own skin and tissue, according to a study from the University of Florida. 2012 Nov 22;491(7425):527. There are abundant hair follicles and glands in its skin and relatively less connective tissue, which allows the skin to shear with very little tension. CrossRef Google Scholar. Brant believes if he can determine how the mouse regenerates skin, he may be able to unlock how to apply it to people. Comparing Acomys scar-free healing from Mus scarring identifies gene expression differences that discriminate … WIHN occurs more robustly in African spiny mice (Acomys cahirinus), which undergo autotomy to escape predation. Regen Med. In the African Spiny Mouse (Acomys), histology on response to extensive wounding in ear tissue and skin shows complete scar-less regeneration of dermis, epidermis (including hair follicles), elastic cartilage, adipose tissue, abundant angiogenesis and unequivocal presence of muscle and nerve fibres in the regenerated tissue. Brant is studying the African spiny mouse, which can regenerate scar-free skin, even after losing mass amounts in an attack. This is even the case if they lose large amounts of skin in an attack. For comparison, a house mouse’s skin is around 20 times stronger than a spiny mouse’s, and can absorb 77 times more energy before breaking. They can regenerate skin that is scar-free. Here we report the first demonstration of skin autotomy in Mammalia (African spiny mice, Acomys). Acomys (spiny mouse) is a newly discovered mammal which can regenerate several tissues. The African spiny … • African spiny mouse, (genus Acomys), any of more than a dozen species of small to medium-sized rodents characterized by the harsh, inflexible spiny hairs of their upperparts. is an emerging animal model with remarkable biological characteristics that make it a subject of interest for a broad range of research fields. • A blunted immune system may play a role the regenerative behavior. A comment on this article appears in "African spiny mouse: Real skin shedding meets mythology." During regeneration, new hair follicles and glands emerge in a basket-weave network of … Following skin loss, rapid wound contraction was followed by hair follicle regeneration in dorsal skin … The term spiny mouse refers to any species of rodent within the genus Acomys. 2F). Similar in appearance to mice of the genus Mus, spiny mice are small mammals with bare, scaled tails.However, their coats are endowed with unusually stiff guard hairs similar to the spines of a hedgehog; this trait is the source of the common name, spiny mouse. The African spiny mouse (Acomys spp.) Documented cases of tissue regeneration … Here we report the first demonstration of skin autotomy in Mammalia (African spiny mice, Acomys). scar) in response to tissue injury as most other mammals, including humans, do. For a mammal, it displays surprising powers of regeneration because it does not fibrose (i.e. For most mammals, this would be a disaster. • Internal organs respond to ischemia by greatly reduced fibrosis. The African spiny … Researchers from the University of Florida found that the spiny mouse loses up to 60 percent of its skin if pulled off but that the skin is rapidly regenerated. This phenomenon is possible owing to the unique composition of the African spiny mouse’s skin. A comment on this article appears in "Rapid healing and skin regeneration in the African spiny mouse." … A mouse that escapes predators by shedding patches of its skin may shed light on regeneration and could lead to research that one day helps people heal from wounds and disease, scientists say. Nature. Unfortunately, what enables this adult mouse’s with this remarkable ability to regenerate normal … Regeneration, 3 (2016), pp. toggle caption. 2013 Jan;8(1):17-8. Mechanical testing revealed a propensity for skin to tear under very low tension and the absence of a fracture plane. The phenomenon of postinjured skin regeneration in mammalian fetuses occurs up to the third trimester of gestation in sheep ... I.M. Because the mouse skin healed so quickly, less collagen was deposited, resulting in no visible scarring. Because the mouse skin healed so quickly, less collagen was deposited, resulting in no visible scarring. The spiny mouse (Acomys species) has emerged as an exciting research organism due to its remarkable ability to undergo scarless regeneration of skin wounds and ear punches. To understand the regenerative ability of the spiny mouse, we characterized skin features such as hair types, hair cycling, … The African spiny mouse (Acomys percivali) can regenerate skin when wounded and even regrow ears that had been punctured. Advancements in science on a number of fronts have led to a whole array of innovations to treat skin … This is a very exciting result and may lead to discoveries in how to regenerate missing muscle segments in humans. 52-61.
