First sign of life of long-extinct cells
Yuka, the Name of a mammoth lady, who is frozen in front of 28,000 years in Siberia. The woolly mammoth was discovered in 2010 and is considered the best preserved specimen in the world. A Japanese research team has now set itself the goal to bring these species using he DNA back to life.
Japanese Researchers at Kindai University, Osaka, want to make it possible, prehistoric life back. The first major step is already done. The Team injected the nuclei from the muscle tissue of the mammoth in the ova of mice, and biological activity. The results of the study were recently published in the journal “Scientific Reports”.
The first steps for the revival of extinct animal species
The extinct woolly mammoth could be earth in the near future again. A Japanese research team transplanted 28,000-year-old nuclei of elephant-like animals in the ova of a mouse. Then, the researchers were able to document the activity of the cell, which takes place shortly before cell division. The full cleavage of the cell not managed so far. Nevertheless, this represents a “significant step towards the revival of the Mammuts“ is, says the author of the study, Kei Miyamoto.
New insights into the Evolution
In addition, the study offers a lot more: The researchers a lot of information about the genetic basis of the Evolution and on factors of extinction have been able to win. For example, the Team was able to reconstruct a woolly mammoth hemoglobin (the color substance in red blood cells), which has an increased tolerance to cold. Furthermore, the scientists discovered the Remains of proteins, and compared them with elephants-proteins and Matches found.
Up to the “Jurassic Park” it will take a while
“We want to in our study, up to the stage of cell division vorrücken“, explained Miyamoto to the English-language newspaper Nikkei Asian Review. But until then, it would still be a whole piece of work. The researchers keep the damage to the mammoth DNA responsible for the failed cell division. In further experiments the researchers want to now using the most modern technology to the less damaged mammoth cell nuclei. (vb)
