Alligators can regrow their tails, it turns out. Researchers have discovered that these ancient reptiles that date back to dinosaur days and can grow 14 feet long or more can regenerate themselves ...
All cnidarians can regenerate, allowing them to recover from injury and to reproduce asexually. Hydras are simple, freshwater animals possessing radial symmetry and contain post-mitotic cells (cells that will never divide again) only in the extremities. [14] All hydra cells continually divide. [15]
Alligators grow a successional tooth (a small replacement tooth) under each mature functional tooth for replacement once a year, each tooth being replaced up to 50 times in the alligator's life. [7] Crocodilia are researched for tooth regeneration in humans. [7]
Hox genes play a massive role in some amphibians and reptiles in their ability to regenerate lost limbs, especially HoxA and HoxD genes. [1]If the processes involved in forming new tissue can be reverse-engineered into humans, it may be possible to heal injuries of the spinal cord or brain, repair damaged organs and reduce scarring and fibrosis after surgery.
Human remains were spotted in the mouth of a 13-foot, 8.5-inch alligator on Friday, in a canal just north of the Florida Botanical Gardens in Largo. The gator was extracted from the water and ...
In humans, stems cells allow limited regeneration of certain cells in our body (which is why they’re central to the exploration of anti-aging therapies), however, other animals display much ...
Inhibition of p38 MAP kinase was found to induce mitosis in adult mammalian cardiomyocytes, [49] while treatment with FGF1 and p38 MAP kinase inhibitors was found to regenerate the heart, reduce scarring, and improve cardiac function in rats with cardiac injury. [50] One of the most promising sources of heart regeneration is the use of stem cells.
Unlike the limited regeneration seen in adult humans, many animal groups possess an ability to completely regenerate damaged tissue. [4] Full limb regeneration is seen both in invertebrates (e.g. starfish and flatworms which can regenerate fully functioning appendages) and some vertebrates, however in the latter this is almost always confined to the immature members of the species: an example ...
