Regeneration, in biology, the process by which some organisms replace or restore lost or amputated body parts. Organisms differ markedly in their ability to regenerate parts. Some grow a new structure on the stump of the old one. By such regeneration whole organisms may dramatically replace.
The meaning of REGENERATION is an act or the process of regenerating : the state of being regenerated. How to use regeneration in a sentence.
Regeneration occurs in organisms like hydra, flatworms, tapeworms. They have highly adaptive regenerative capabilities. When an organism is wounded, its cells are activated and the damaged tissues and organs are remodelled back to the original state.
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.
Regeneration means the regrowth of a damaged or missing organ part from the remaining tissue. As adults, humans can regenerate some organs, such as the liver. If part of the liver is lost by disease or injury, the liver grows back to its original size, though not its original shape.
Jan 1, 2018 · The combination of review articles and primary research articles in this Special Issue on Regeneration cover a wide range of diverse aspects of how tissue regeneration is orchestrated at a cell and molecular level.
Regeneration - Cell Growth, Tissue Repair, Stem Cells: Following amputation, an appendage capable of regeneration develops a blastema from tissues in the stump just behind the level of amputation (see photograph). These tissues undergo drastic changes.
Dec 11, 2023 · Most research organisms used to study regeneration can regrow body parts that humans can’t. The planarian can regenerate its entire body from one small piece of tissue, and the zebrafish can repair significant damage to its heart, fins, pancreas, eyes, brain, and spinal cord.
Nov 9, 2023 · This Perspective highlights the fundamental questions in the regeneration process from start to finish and how they might be addressed to facilitate cross-species studies.
Jun 28, 2024 · Regeneration articles from across Nature Portfolio. Regeneration is the process by which lost or damaged tissues, organs or limbs are re-formed from the remaining tissue.
