Their body is populated by adult stem cells called neoblasts, which planarians use for regenerating missing body parts. [6] Many species are able to regenerate any missing organ, which has made planarians a popular model in research of regeneration and stem cell biology. [7]
Synonyms. Dugesia mediterranea. Benazzi, Baguñà, Ballester, Puccinelli & Del Papa, 1975. Schmidtea mediterranea is a freshwater triclad that lives in southern Europe and Tunisia. [2] It is a model for regeneration, stem cells and development of tissues such as the brain and germline. [3][4]
Neoblasts (ˈniːəʊˌblæst) are adult stem cells found in planarian flatworms. They are the only dividing planarian cells, and they produce all cell types, including the germline. [1][2] Neoblasts are abundant in the planarian parenchyma, and comprise up to 30 percent of all cells. [1] Following injury, neoblasts rapidly divide and generate ...
Regeneration in biology is the process of renewal, restoration, and tissue growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage. [ 1 ] Every species is capable of regeneration, from bacteria to humans. [ 2 ][ 3 ][ 4 ] Regeneration can either be complete [ 5 ...
Planaria. For the common name given to many non-parasitic flatworms, see Planarian. Planaria is a genus of planarians in the family Planariidae. Due to its excellent ability to regenerate, species of Planaria has also been used as model organisms in regeneration studies. [1] When an individual is cut into pieces, each piece has the ability to ...
Epimorphosis. Epimorphosis is defined as the regeneration of a specific part of an organism in a way that involves extensive cell proliferation of somatic stem cells, [1] dedifferentiation, and reformation, [2] as well as blastema formation. [3] Epimorphosis can be considered a simple model for development, though it only occurs in tissues ...
