- The whole limb of a salamander or a triton will grow again and again after amputation. (wikipedia.org)
- salamanders and newts), an order of tailed amphibians, is possibly the most adept vertebrate group at regeneration, given their capability of regenerating limbs, tails, jaws, eyes and a variety of internal structures. (wikipedia.org)
- Here we review recent insights into the biophysical, biochemical, and epigenetic processes that underlie regenerative healing in amphibians, focusing particularly on tail and limb regeneration in Xenopus . (frontiersin.org)
- In urodele amphibians such as axolotls and newts, the same injury is followed by scarless regenerative healing that can fully restore both the lost tissue and its function (reviewed in Tanaka, 2016 ). (frontiersin.org)
- At its most elementary level, regeneration is mediated by the molecular processes of gene regulation and involves the cellular processes of cell proliferation, morphogenesis and cell differentiation. (wikipedia.org)
- Limited regeneration of limbs occurs in most fishes and salamanders, and tail regeneration takes place in larval frogs and toads (but not adults). (wikipedia.org)
- Elegant experiments using heat-shock inducible expression of inhibitory proteins have further refined these observations to establish epistatic relationships, in which BMP acts upstream of Wnt, which in turn acts upstream of FGF during regeneration of the limb bud and tail ( Lin and Slack, 2008 ). (frontiersin.org)
- After the limb or tail has been autotomized, cells move into action and the tissues will regenerate. (wikipedia.org)
- Injuries that sever tissues such as the limb or spinal cord are met with radically different outcomes among vertebrates. (frontiersin.org)
- The case of autotomy, for example, serves as a defensive function as the animal detaches a limb or tail to avoid capture. (wikipedia.org)
- Many arthropods can regenerate limbs and other appendages following either injury or autotomy. (wikipedia.org)
- All these strategies result in the re-establishment of appropriate tissue polarity, structure and form. (wikipedia.org)

- Some lower order vertebrates such as salamanders and newts have the ability to regrow severed limbs through a process called epimorphic regeneration. (nih.gov)
- Many arthropods can regenerate limbs and other appendages following either injury or autotomy. (wikipedia.org)
- The current state of the science suggests that focused investment in research on key aspects of epimorphic regeneration is necessary for developing strategies to regenerate limbs in higher vertebrates and mammals including humans. (nih.gov)
- The axolotl is one of the few tetrapods that are capable of regenerating complicated biological structures, such as complete limbs, throughout adulthood. (nih.gov)
- In this review we focus on the crucial early events that occur during wound healing, the neural-epithelial interactions that drive the formation of the early blastema, and how these mechanisms differ from those of other species that have restricted regenerative potential, such as humans. (nih.gov)
- The 5'Hox genes play crucial roles in limb development and specify regions in the proximal-distal axis of limbs. (bvsalud.org)
