Mammoths ‘to roam Earth again’ after scientists make HUGE breakthrough

Cell nuclei from the muscle tissue was injected into mouse egg cells.

The research - published Monday in the journal Scientific Reports - doesn't provide much hope for Jurassic Park-style resurrection of long-extinct species just yet, he cautioned.

Scientists in Japan say they have taken a "significant step" in their efforts to bring back the extinct woolly mammoth, the Independent newspaper is reporting.

The team experimented with what they called are "well-preserved" tissue samples from the animal's bone marrow and muscle, which allowed them to collect as many as 88 nucleus-like structures, further sewn into mouse oocytes, a cell in an ovary.

Of those, five displayed the biological reactions that happen just before cell division begins, said Kei Miyamoto, a member of the team at Kindai University in western Japan.

They also found possible signs of fix to damaged mammoth DNA.

However, the predivision development stopped before completion in all the ova.

"Yuka's cell nuclei were more damaged than we thought, and it would be hard to resurrect a mammoth as things stand", said team member Kei Miyamoto, a lecturer in developmental biology at Kindai University. "There's a chance, if we can obtain better-preserved nuclei".

Miyamoto and his colleagues are working with researchers in Russian Federation to bring mammoths back to life using cloning technology called somatic cell nuclear transfer.

"We want to move our study forward to the stage of cell division", he added, acknowledging though that "we still have a long way to go".

With their enormous shaggy torsos and long curved tusks, the imposing creatures last walked on earth during the Ice Age.
