Scientists One Step Closer to Bringing 28,000-Year-Old Woolly Mammoths Back to Life

Scientists took cell nuclei from a woolly mammoth that lived in Siberia more than 28,000 years ago and implanted them into the cells of living mice.


Scientists are working on bringing the woolly mammoths back to life.

A new study published in scientific reports explains the recent approach experts took in bringing extinct species back to life.

They took the cells from a wooly mammoth that exited on earth some 28,000 years ago and inserted them into the cells of living mice.

Reports suggest that out of the dozens of implanted cells, five showed essential biological reactions that are needed for cell division to take place.

The scientists took Nuclei from the bone marrow as well as the muscle tissue of a well-preserved Woolly Mammoth specimen that was found in Siberian permafrost in 2011.

And while scientists observed some of the essential biological reactions that are needed for cell division to take place, they added that none of them actually produced cell division crucial for mammoth rebirth.

This means that we won’t be seeing Woolly mammoths running around the planet anytime soon.

But it does mean that scientists are on the right track to possibly being able, in the not so distant future, bring back rare, extinct species to life.

Kei Miyamoto, a scientist at Kindai University in western Japan who conducted the experiment, said in an interview with AFP:

“This suggests that, despite the years that have passed, cell activity can still happen and parts of it can be recreated. Until now many studies have focused on analyzing fossil DNA and not whether they still function.”

Miyamoto explains that he and his colleagues observed how nuclei were able to create cellular structures that are considered a precursor to cell division.

But this doesn’t mean we will have Jurassic Park animals running around anytime soon, the researchers cautioned.

“We have also learned that damage to cells was very profound,” Miyamoto said. “We are yet to see even cell divisions. I have to say we are very far from recreating a mammoth.”

Scientists from Kindai University worked with colleagues from Russia to find means and ways to possibly clone to Mammoth in the near future.

“We need new technology, we want to try various approaches,” Dr. Miyamoto explained.

“Our work provides a platform to evaluate the biological activities of nuclei in extinct animal species. Ancient species carry invaluable information about the genetic basis of adaptive evolution and factors related to extinction,” the scientists wrote in the journal Scientific Reports.
