On the planet inhabited by many creatures that can not a little surprise. sometimes nature can create truly amazing and unique living organisms. The life cycle of any organism begins with birth and ends with death. This is a natural process. But as it turned out, there are on the Earth, who found a way to move beyond such a life-cycle. Recently a group of biologists from the United States were openly openly animal that can live forever.
The status of the only immortal animal was awarded to the jellyfish Turritopsis nutricula. She lives in the depths of tropical seas, has a very small size (about 3-5 mm), but the most interesting that Medusa has learned to rejuvenate itself. How she did it? Actually, it’s pretty simple: when the body reaches adulthood — he does not die. Medusa falls to the seabed, then covered with a chitinous crust. After that, she transforms into a polyp. Under a layer of chitin of all the cells of the jellyfish is completely updated and individual from the adult goes back to the initial phase of its development. After this “rejuvenated” Medusa struggles out from under the chitinous layer and continues its life cycle until, until you grow old. After that, the upgrade process starts again. So can continue indefinitely.
At the moment, scientists are studying this phenomenon. It is assumed that the jellyfish have learned to manage their own genes, influencing the process of formation of new cells. But this is how she “turns back time” is not clear. Because the aging cells of all known organisms can no longer “roll back” to its original state. However, after exit from under the chitinous cover in the body of updated jellyfish cells are in the same condition as immediately after birth. Find out how this process works we can expect really interesting discoveries, aimed at the fight against aging and in the development of regenerative medicine.
