Sunflower sea star regenerates its arms. Regeneration in biology is the process of renewal, restoration, and tissue growth that makes genomes, cells, organisms, and ecosystems [ [Resilience (ecology)|resilient]] to natural fluctuations or events that cause disturbance or damage. [ 1 ] Every species is capable of regeneration, from bacteria to ...
Regeneration in humans is the regrowth of lost tissues or organs in response to injury. This is in contrast to wound healing, or partial regeneration, which involves closing up the injury site with some gradation of scar tissue. Some tissues such as skin, the vas deferens, and large organs including the liver can regrow quite readily, while ...
Alejandro Sánchez Alvarado is a molecular biologist, an Emeritus Investigator of the Howard Hughes Medical Institute, and President and Chief Scientific Officer of the Stowers Institute for Medical Research. The Sánchez Alvarado Laboratory focuses on understanding the regenerative capabilities of the planarian flatworm Schmidtea mediterranea.
Michael Levin is an American developmental and synthetic biologist at Tufts University, where he is the Vannevar Bush Distinguished Professor. [3] Levin is a director of the Allen Discovery Center at Tufts University and Tufts Center for Regenerative and Developmental Biology. [3] He is also co-director of the Institute for Computationally ...
Liver regeneration is the process by which the liver is able to replace damaged or lost liver tissue. The liver is the only visceral organ with the capacity to regenerate. [ 1 ] [ 2 ] The liver can regenerate after partial hepatectomy or injury due to hepatotoxic agents such as certain medications, toxins, or chemicals. [ 3 ]
Blastema cells surrounded by transparent cystic spaces. A blastema (Greek βλάστημα, "offspring" [1]) is a mass of cells capable of growth and regeneration into organs or body parts. The changing definition of the word "blastema" has been reviewed by Holland (2021). [2] A broad survey of how blastema has been used over time brings to ...
Regenerative medicine also includes the possibility of growing tissues and organs in the laboratory and implanting them when the body cannot heal itself. When the cell source for a regenerated organ is derived from the patient's own tissue or cells, [ 3 ] the challenge of organ transplant rejection via immunological mismatch is circumvented.
Fission (biology) Fission, in biology, is the division of a single entity into two or more parts and the regeneration of those parts to separate entities resembling the original. The object experiencing fission is usually a cell, but the term may also refer to how organisms, bodies, populations, or species split into discrete parts. [1][2][3 ...
