Scientists Mark 'Significant Step' in Bringing Back Woolly Mammoths

Scientists then injected cell nuclei from the extinct woolly mammoth's muscle tissue into mouse cell eggs - resulting in signs of biological activities, according to the study, published by Nature's on-line journal Scientific Reports. However, researchers caution that it's unlikely the extinct creatures will walk the Earth again anytime soon.

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.

"The mammoth nuclei showed the spindle assembly, histone incorporation and partial nuclear formation; however, the full activation of nuclei for cleavage was not confirmed", the team wrote in their study.

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".

The mammoth was found in 2011 in Siberia, and despite the warnings of all the Jurassic Park films, scientists apparently decided it might be fun to try to bring it to life.

They also found possible signs of fix to damaged mammoth DNA. "Once we obtain cell nuclei that are kept in better condition, we can expect to advance the research to the stage of cell division".

The research is part of a project at Kindai University to revive the woolly mammoth.

According to the team, scientists in Japan and South Korea have pursued research to recreate a mammoth using cloning technology, while scientists in Europe and the United States are experimenting with genome editing technology in the same quest.

The last woolly mammoth herds disappeared over 4,000 years ago due to drastic climate change, but the enormous prehistoric creatures could soon be back, wandering the Earth like they did during the ice age.
