Another study in “Nature” showed that the cells of the fossil remains of mammoths have biological activity so far, After it was transplanted into mice cells.
If what the study claims is possible, the discovery will become a milestone in science, Because it will deal with the relative “rebirth” of animal species Long extinct, published by El Universal.
According to the publication, cells experimented with by a group of Japanese scientists were removed from a fossilized specimen dating back more than 28,000 years.
Mammoths are called yucca and have been frozen All the time mentioned it was found in Siberian permafrost.
However, before the study began, experts compared the species’ DNA with that of a group of elephants, To determine the genomic similarities between one and the other.
Next, they were responsible for isolating the nuclei of the least damaged yucca, to observe the dynamics through which they operate, after implanting them (by nuclear transfer) into rat eggs, a type of female rat germ cell. .
Later, the researchers encountered a great surprise, and realized that, Mammoth remains are still trapped with nuclear components.
As a result, the study published in 2019 in “Scientific Reports” monitored the process that occurs before cell division, Which could lead to the potential possibility of repairing DNA damage to extinct species.
While Kei Miyamoto, the study’s lead author, emphasized that this may be the step that leads to the mammoth resurrection, but more importantly, It can provide invaluable evidence of the genetic basis of a species, Which helps to understand evolutionary and adaptive processes.

Although at the time, Miyamoto realized they still had a long way to go, in terms of cellular vision, they had dedicated themselves in recent years to developing cloning technology, through somatic cell nuclear transfer.
