- Regeneration | Definition, Process, Examples, Facts | Britannica
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
- Regeneration - Cell Growth, Tissue Repair, Stem Cells | Britannica
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 - Students | Britannica Kids | Homework Help
In biology, regeneration refers to the process by which plants and animals replace lost or damaged parts by growing them anew Some animals can regenerate their limbs, tails, or even parts of internal organs, such as the liver
- Regeneration - Tissue, Organ, Limb | Britannica
Regeneration - Tissue, Organ, Limb: Virtually no group of organisms lacks the ability to regenerate something This process, however, is developed to a remarkable degree in lower organisms, such as protists and plants, and even in many invertebrate animals such as earthworms and starfishes
- Regeneration - Tissue, Organ, Limb | Britannica
Regeneration - Tissue, Organ, Limb: Not all organisms regenerate in the same way In plants and in coelenterates such as the hydra and jellyfishes, missing parts are replaced by reorganization of preexisting ones
- Fragmentation | biology | Britannica
Fragmentation is a common method of reproduction used by some species of asteroids, ophiuroids, and holothurians, and in some of these species sexual reproduction is not known to occur Successful fragmentation and regeneration require a body wall…
- Morphallaxis | Regeneration, Tissue Repair Cell Differentiation . . .
Morphallaxis, a process of tissue reorganization observed in many lower animals following severe injury, such as bisection of the animal, and involving the breakdown and reformation of cells, movement of organs, and redifferentiation of tissues The result is usually a smaller but complete
- Regenerative medicine - Tissue Scaffolds, Repair Factors | Britannica
Further understanding of the molecular biology of wound repair and regeneration will likely result in the design of combinations of scaffolds and soluble natural factors or synthetic small molecules that confer regenerative capacity on regeneration-deficient tissues
