The axolotl or Ambystoma mexicanum is the last survivor. When the axolotl falls on a leg, tail, or part of its heart, part of its body regrows and leaves little or no scarring. But the hardy creatures are on the verge of extinction.
Axolotl is also a minus of conservation. The main symbol is the national symbol of Mexico and is a worldwide animal lover because it breeds easily in the aquarium. There are a lot of axolotls in captivity, so some restaurants in Japan make axolotls as a snack. Thousands of axolotls are also used each year in clinical trials. Axolotl has been studied in laboratories around the world due to its ability to work well. However, contamination and axolotl loss was limited to the location, pollution, and water from the Xochimilco Canal around Mexico City, making the axolotl less visible.
The man and the axolotl have long had a close relationship. When the Spaniards or “Aztecs” occupied the area around Lake Texcoco in the 13th century and established a town in the middle of the lake as their capital, the axolotl flourished in and around a canal. The animal was named after the Aztec god “Xolotl”, who is said to have converted into an axolotl to avoid sacrifice. As the Aztec nation grew, it became more capital and fewer lakes. The remnants of Lake Texcoco are today polluted canals and lakes in Xochimilco, southern Mexico City. If you are axolotl lover then you can easily get it from axolotl for sale. This is a trusted site for axolotls.
And since the wet ground disappears, the axolotl does just that. The first high number of axolotls in 1998 estimated that there were around 6,000 animals per square km. When ecologist Luis Zambrano of the National Autonomous University of Mexico (UNAM) did his calculations in 2015, he found just 35 per square kilometer.
Axolotl is the world’s oldest self-contained animal capable of testing. This decline has also led to the success of the axolotl in aquariums and laboratory sites around the world. In 1804, the scientist Alexander von Humboldt sent two models of a wine cellar to Paris. Humboldt and other early researchers had already found other characteristics of the axolotl. While other salamanders metamorphose into land animals when they achieve sexual contact, the axolotl grabs feathered gills and stays in the water for its entire life. According to Stephen Jay Gould, axolotls are “sexually mature tadpoles”.
Axolotls entered the laboratory in 1863 when a French expedition sent 34 of them to the Museum of Natural History in Paris. Five men and one woman were sent to the French vet Auguste Duméril with great success. Duméril distributes axolotls to institutions and individuals throughout Europe. They were bred in the last century in many laboratories, making the axolotl the oldest self-developed experimental population.
Attractive and unusual experiments over the past 150 years have provided a wealth of information about the axolotl’s ability to regenerate and repair. For example, an amputated axolotl limb is fully regenerated and functions as the first limb after multiple amputations. The axolotl’s cells “know” that the pattern will repeat: if the arm is cut at the shoulder, the entire arm will repeat. However, when the arm is cut at the elbow, only the forehead and arms grow back. When an arm is severed from the wrist, only the hand regrows.
Another initial experiment was studied in more detail. When regenerating tissue is transplanted from an amputated left arm to an amputated arm and vice versa, the axolotl strangely grows three new branches instead of just one. These two are fruits. Another surprise was that Axolotls could receive a head replacement without confirmation.
It may sound like mad scientists writing, but the (somewhat unusual) experiments that demonstrated these regenerative abilities are an important basis for understanding regeneration in axolotls and why it doesn’t work in animals. In animals, like humans, scar formation develops rapidly and interferes with tissue regeneration
. On the other hand, the axolotl can repair deep tissues without leaving scars. This is thanks to the blastema, a group of cells that covers the wound amputation. While macrophages, a type of immune system that allows cells to die, cause scarring in animals, scientists have found that in the axolotl, macrophages are essential for wound healing and regeneration. This blastema is also the reason the axolotl can regenerate a ruptured (or ruptured) liver.
Although many questions remain unanswered, scientists are interested in determining how the molecule modulates axolotl limb regeneration. However, health scientists are not limited to the axolotl. They focus on understanding why animals are so bad at regeneration. Mice and older humans can regain lost fingers as they age, giving scientists hope that they can regain our ability to regenerate.
However, it is unclear how much longer scientists can work with the axolotl. Like many animals in the clinic, these animals give birth, which can be life-threatening. To measure the microcosm of genes, scientists used an “inbreeding coefficient”. Identical twins have a combined score of 100 and different identical individuals have an equivalence of 0. For healthy growth, captives should have an equivalence greater than 12.5. The famous Spanish inbreeding of the Habsburgs had a coefficient of
