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.
In 2022, a cocktail of drugs and hormones (1,4-DPCA, BDNF, growth hormone, resolvinD5, and retinoic acid), in a single dose lasting 24 hours, was shown to trigger long-term leg regeneration in adult X. laevis. Instead of a single spike, a paddle-shaped growth is obtained at the end of the limb by 18 months.

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.
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.
May 14, 2008 · By contrast, early in gestation, injured fetal tissues can be completely recreated, without fibrosis, in a process resembling regeneration. Some organisms, however, retain the ability to ...
Jul 1, 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.
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.
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.
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.
