Cells from a woolly mammoth that died 28,000 years ago have begun to show "signs of biological [activity]" after they were implanted in mouse cells.
However, researchers caution that it's unlikely the extinct creatures will walk the Earth again anytime soon.
The research, published in Scientific Reports, details how a well-preserved woolly mammoth, found in 2011 in the Siberian permafrost, has begun to show some activity.
"Until now many studies have focused on analyzing fossil DNA and not whether they still function," Miyamoto added.
The study's abstract reveals "[i]n the reconstructed oocytes, the mammoth nuclei showed the spindle assembly, histone incorporation and partial nuclear formation; however, the full activation of nuclei for cleavage was not confirmed."
However, there were varying levels of DNA damage done, which the researchers said "were comparable to those of frozen-thawed mouse sperm and were reduced in some reconstructed oocytes."
While some evidence of biological processes were seen, the damage the elements had on the cells are not enough for bringing the mammoth back to life, eschewing any kind of "Jurassic Park-style resurrection" that many have hoped for, Miyamoto said.
"We have also learned that damage to cells was very profound.
We are yet to see even cell divisions.
I have to say we are very far from recreating a mammoth."
Woolly mammoths went extinct more than 4,000 years ago, with some scientists believing they died off from the changing climate and human hunters.

“ They should use elephant cells, not mouse cells....... “
Maybe we should try to contact these experimenters and let them know.

Maybe they want to create a small version before they go Big Time!
Nah. You’re wrong. Mad Max can’t eat brains. She’s allergic :)
You may recall that at the end of the last Jurassic movie, a bunch of captive dinosaurs on the mainland escaped. I presume another movie might be in the works. Does anyone have information about that??
I haven’t yet seen the latest JP movie.
Was it a sequel to Jurassic World?
If the producers live long enough and made enough off that sequel, there will be another one! :^)
I predicted this to Sunken Civ as far back as the first discovery of a DNA potential carcass. And followed up over the years with dire predictions of where this cloning was going in the animal world.
It might have even been before Jurassic Park. What would be a logical purpose for all the cost and research to bring back an animal that lost the evolutionary race? Dolly the sheep was at least a benign creature if it worked out.
The last mammoth remains are not as old as the Great Pyramid. The fact is, mammoths died suddenly and simultaneously for the most part -- the surviving lines were isolated, somehow protected from the fate of all the others, and genetically quite narrow due to that isolation. They didn't go extinct because they weren't well adapted, according to the autopsies, they lived on buttercups when nothing else was available (like Snickers Bars).
