A lens regeneration technique was trialled in a collaboration between Sun Yat-sen University and University of California, San Diego which was published in 2016. [8] The capsule of the lens was pierced with a smaller cut than in conventional cataract surgery – just 1–1.5 mm – and drained of its contents clouding the vision causing cataracts.
Tiger salamanders have been shown to travel up to 255 meters after their breeding cycles are complete, which is likely them returning to their original home ranges. [21] Some research has shown that females will travel farther than males. [22] However, a single tiger salamander has only a 50% chance of breeding more than once in its lifetime.
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]
Stunning salamander could hold key to cell regeneration This creature is the stuff of myths but is actually real. Revered as a god by the Aztecs, the axolotl isn't your typical salamander.
The tail drops off and wriggles around for a while after an attack, and the salamander either runs away or stays still enough not to be noticed while the predator is distracted. The tail regrows with time, and salamanders routinely regenerate other complex tissues, including the lens or retina of the eye. Within only a few weeks of losing a ...
The mole salamanders (genus Ambystoma) are a group of advanced salamanders endemic to North America. The group has become famous due to the study of the axolotl (A. mexicanum) in research on paedomorphosis, and the tiger salamander (A. tigrinum, A. mavortium) which is often sold as a pet, and is the official amphibian of four US states.
TIG1 contains two faces: the first face contains homology to the protein latexin, and the second contains a broad basic patch. The basic face is thought to be an interaction surface. Supporting the idea of a protein interaction surface, TIG1 also contains a cis- peptide bond between isoleucine-122 and proline-123 on a protruding loop that lies ...
When the limb of the salamander is cut off, a layer of epidermis covers the surface of the amputation site. In the first few days after the injury, this wounded epidermis transforms into a layer of signaling cells called the Apical Epithelial Cap (AEC), which has a vital role in regeneration.
