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. 2012 Nov 22;491(7425):527. Here we report the first demonstration of skin autotomy in Mammalia (African spiny mice, Acomys). Regen Med. The African spiny mouse has the ability to regrow large patches of skin and hair without scarring. • A blunted immune system may play a role the regenerative behavior. This is a very exciting result and may lead to discoveries in how to regenerate missing muscle segments in humans. Unfortunately, what enables this adult mouse’s with this remarkable ability to regenerate normal … For most mammals, this would be a disaster. In addition to the skin, the ear and skeletal muscle the Acomys heart also shows regenerative … 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. The spiny mouse can thus regenerate each of the three types of muscle: smooth, skeletal and cardiac and here I describe the circumstances under which this may provide some important avenues for extrapolation to humans. Regenerative Medicine Program, Department of Biomedical Sciences and Medicine, University of Algarve, 8005‐139 Faro, Portugal . It has been shown that in highly regenerative animals such as salamanders and zebrafish, macrophages are necessary to initiate tissue regeneration. The term spiny mouse refers to any species of rodent within the genus Acomys. Offering new novel treatments whom have suffered from horrific and … When they examined tissue regeneration after the loss of skin from the back, the researchers found that new skin cells and hair follicles (the cells embedded in the skin, from which hairs grow) were also regenerated in the deposited sections of collagen. But when the spiny mouse skin regenerates the missing segment of the panniculus carnosus regenerates as well (Fig. The African spiny … Specific objectives: Comparative proteomic analysis of skin regeneration in Acomys and Mus. 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. Nature. After skin loss, rapid wound contraction was followed by hair follicle regeneration in dorsal skin wounds. The African spiny mouse may hold the key to understanding skin regeneration, say scientists. Ear wound regeneration in the African spiny mouse Acomys cahirinus. 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 is even the case if they lose large amounts of skin in an attack. A comment on this article appears in "Regenerative biology: Skin… 52-61. Brant is studying the African spiny mouse, which can regenerate scar-free skin, even after losing mass amounts in an attack. • The spiny mouse, Acomys spp., is a recently described model organism for regeneration studies. WIHN occurs more robustly in African spiny mice (Acomys cahirinus), which undergo autotomy to escape predation. A comment on this article appears in "Rapid healing and skin regeneration in the African spiny mouse." The African spiny mouse (Acomys percivali) can regenerate skin when wounded and even regrow ears that had been punctured. Araújo, D. Power, G. TiscorniaEar wound regeneration in the African spiny mouse Acomys cahirinus. Advancements in science on a number of fronts have led to a whole array of innovations to treat skin …
