Lizard Tail Will Help Humans Rebuild Body Parts

As you know, lizards have one feature that has long been of interest to humanity. In the event of an attack by a predator, the lizard can discard its tail and then grow it back. Recently, scientists from the University of Arizona announced that they were able to decipher the code responsible for the regeneration process of the tail lost by the lizard. They hope that their research can be useful in the field of regenerative medicine.

According to Professor Kenro Kusumi, lead author of the research article, lizards are the closest animals to humans, capable of restoring whole limbs. In addition, they have the same set of genes as we do, therefore, in theory, a person is also able to regenerate, you just need to find the right genes and use them correctly.

Through molecular and computer analysis, scientists have determined that at least 326 different genes are involved in tail regeneration. Among them are those that are responsible for wound healing, embryonic development and hormonal regulation.

The researchers also identified one type of satellite cell that plays a key role in regeneration - cells that are precursors of skeletal muscle cells. And humans also have these cells. It remains to be hoped that thanks to new discoveries, in the future the word "amputation" will forever lose its shade of despair.
