… But when the spiny mouse skin regenerates the missing segment of the panniculus carnosus regenerates as well (Fig. Spiny … Smooth muscle: In the dermis, there are two structures that contain smooth muscle cells, namely the … The African spiny mouse (Acomys spp.) After skin loss, rapid wound contraction was followed by hair follicle regeneration in dorsal skin wounds. The military scientists feel if they can determine how the Spiny Mouse regenerates its own skin then perhaps this can be applied to humans. Because the mouse skin healed so quickly, less collagen was deposited, resulting in no visible scarring. • The skin regenerates after removal or burn injury and so do ear punches. Here we report the first demonstration of skin autotomy in Mammalia (African spiny mice, Acomys). • A blunted immune system may play a role the regenerative behavior. Mechanical testing revealed a propensity for skin to tear under very low tension and the absence of a fracture plane. 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. 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. Ear wound regeneration in the African spiny mouse Acomys cahirinus. 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. Nature. Acomys (spiny mouse) is a newly discovered mammal which can regenerate several tissues. Advancements in science on a number of fronts have led to a whole array of innovations to treat skin … The African spiny mouse (Acomys percivali) can regenerate skin when wounded and even regrow ears that had been punctured. 52-61. Satish and Kathju, … Typically a desert species adapted to a low-calorie diet, spiny mice develop diabetes-related symptoms when switched to high-energy diets. The African spiny mouse (Acomys spp.) CrossRef Google Scholar. 2013 Jan;8(1):17-8. A comment on this article appears in "Regenerative biology: Skin… This phenomenon is possible owing to the unique composition of the African spiny mouse’s skin. 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. By Charles Choi updated 9/26/2012 6:44:07 PM ET 2012-09-26T22:44:07 Araújo, D. Power, G. TiscorniaEar wound regeneration in the African spiny mouse Acomys cahirinus. toggle caption. … 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. The term spiny mouse refers to any species of rodent within the genus Acomys. can heal full thickness excisional skin wounds in a scar-free manner with regeneration of all dermal components including hair and associated structures. 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. A comment on this article appears in "African spiny mouse: Real skin shedding meets mythology." 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. The African spiny … Center for Biomedical Research, CBMR, University of Algarve, 8005‐139 Faro, Portugal. The African spiny mouse has the ability to regrow large patches of skin and hair without scarring. Ashley W.
