Skeletal muscle dedifferentiation during salamander limb regeneration.
Salamanders can regenerate entire limbs throughout their life. A critical step during limb regeneration is formation of a blastema, which gives rise to the new extremity. Salamander limb regeneration has historically been tightly linked to the term dedifferentiation, however, with refined research tools it is important to revisit the definition of dedifferentiation in the context. To what exten...
متن کاملRegeneration in plants and animals: dedifferentiation, transdifferentiation, or just differentiation?
The textbooks and literature of plant biology indicate that plant cells are totipotent, and that regeneration occurs via dedifferentiation, by which the cell and its descendents recapitulate earlier stages of development. However, recent work on the generation of callus, a presumed undifferentiated or dedifferentiated and disorganized cellular mass, indicates that the cells of callus are neithe...
متن کاملLong-Duration Muscle Dedifferentiation during Limb Regeneration in Axolotls
Although still debated, limb regeneration in salamanders is thought to depend on the dedifferentiation of remnant tissue occurring early after amputation and generating the progenitor cells that initiate regeneration. This dedifferentiation has been demonstrated previously by showing the fragmentation of muscle fibers into mononucleated cells and by revealing the contribution of mature muscle f...
متن کاملA developmentally regulated switch from stem cells to dedifferentiation for limb muscle regeneration in newts.
The newt, a urodele amphibian, is able to repeatedly regenerate its limbs throughout its lifespan, whereas other amphibians deteriorate or lose their ability to regenerate limbs after metamorphosis. It remains to be determined whether such an exceptional ability of the newt is either attributed to a strategy, which controls regeneration in larvae, or on a novel one invented by the newt after me...
متن کاملEvidence for dedifferentiation and metaplasia in amphibian limb regeneration from inheritance of DNA methylation.
Amphibian limb regeneration is a process in which it has been suggested that cells of one differentiated type may dedifferentiate and give rise to cells of another type in the regenerate. We have used two tissue-specific hypomethylations in the newt cardioskeletal myosin heavy chain gene as lineage markers to follow the fate of cells during limb regeneration. Analysis of genomic DNA from differ...
