Can the DNA of a Salamander to help restore the lost limbs of man? Source:

Imagine that almost any part of the body can be regenerated. How to change our life? Don't know about you, but my first Association with regeneration connected with Hugh Jackman, but rather with them played the character in “X-Men” Wolverine. Though actually the first and only creature of whom we all think, if it comes to regeneration is the Salamander. The fact that these amazing can regenerate spinal cord, tail, eyes and some types even lens. According to a press release of the study, scientists announced that DNA salamanders can regenerate parts of the human body. will be published in the journal .

Regeneration — a mystery of nature

Regeneration — one of the most attractive areas of biological research. As some animals can grow back body parts? Is it possible that we get? If scientists were able to uncover the secrets that give these animals such a wonderful , this knowledge could be crucial in medical practice in the future. Scientists from the University of Kentucky decided to approach this idea even closer, announcing that they managed to sequence the genome of the axolotl — salamanders, whose only natural habitat is lake near Mexico city.

Axolotl has long interested scientists as a basic model for . Fully Sequeira the genetic code of the animal itself, the researchers hope that in the future it can be used to treat people. Development of new methods of genetic treatment may lead to the fact that people will be able to restore missing limbs or repair other damage to the body, as do salamanders. The axolotl is capable of regenerating almost any body part, so you can find that they recover not able quite difficult. Limbs, tail, spinal cord, eyes and even half of their brain subject to regeneration. Just think how amazing it is.

Differences in the human genome and salamanders

Sequencing of the human genome today more or less familiar work, but in the case of the genome of salamanders the team needed to invent new methods of sequencing DNA absoluteway — the fact that the genetic code of an animal ten times longer than humans. The method applied by the researchers in the future will allow to sequence a long genome of other animals.

These funny salamanders can repair the damaged part of the brain

In the future, the researchers intend to study the complete DNA sequence of salamanders to learn more about the regenerative abilities of the axolotl. “Now that we have access to genomic information, we can really start to investigate the functions of genes absolutley and learn how they are able to regenerate parts of the body,” — said the study authors in a press release. So maybe someday scientists will be able to use the genome of salamanders and apply it for patients with spinal cord injuries, stroke recovery, joint and... it is certainly not the limit.

the animal itself — the larva neotenic salamanders. This means that it reaches sexual maturity not turned into adult form
