Alejandro Sanchez-Alvarado and Philip Newmark transformed planarians into a model genetic organism in the beginning of the 20th century to study the molecular mechanisms underlying regeneration. [12] Morgan found that a piece corresponding to 1/279th of a planarian [ 11 ] or a fragment with as few as 10,000 cells could regenerate into a new ...
Planarian regeneration combines new tissue production with reorganization to the existing anatomy, morphallaxis. [17] The rate of tissue regrowth varies between species, but in frequently used lab species, functional regenerated tissues are available already 7–10 days following tissue amputation. [ 17 ]

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 regenerate into a fully formed individual. [ 2 ]
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]
Dugesia japonica is a species of freshwater planarian that inhabits freshwater bodies of East Asia, including Japan, Korea, Taiwan, China and northeastern Siberia. [2] However, molecular studies suggest that Dugesia japonica is polyphyletic and different populations across its area of occurrence constitute distinct species.
The Sánchez Alvarado Laboratory focuses on understanding the regenerative capabilities of the planarian flatworm Schmidtea mediterranea. [ 2 ] [ 3 ] [ 4 ] In 2015, Sánchez Alvarado was elected a fellow of the American Academy of Arts and Sciences , and to the National Academy of Sciences in 2018 for his distinguished and continuing ...
