"I believe that non-destructive science can be beneficial in some way or another, and it is clear that regenerating life can be positive, but I would personally prefer that we turn our attention and this sort of knowledge to endangered species that are on the Earth right now," he said. Nevertheless, experts continue to scour the ice fields and permafrost of Siberia in search of specimens of these beasts that may have been sufficiently well preserved to still retain viable cells. That will come as a disappointment to those who saw headlines last year, primarily in the Russian media, predicting that a theme park featuring mammoths, species of long-extinct deer and horses, cave lions and other mammals could be operating within a decade.
"The technology to resurrect an extinct creature does not yet exist, although I will not deny that it probably will in the future," he said. "But we are still many steps away from Jurassic Park," he joked. Work is continuing on the carcass of the mammoth – nicknamed Yuka – to find cells that are less damaged and more viable for the research. Read more: Remember Dolly? The sheep wasn't the only animal cloneĪchieving cell division is the nine-strong team's next task, professor Miyamoto said. While this is a positive development, he said, none of the samples produced the cell division that is required for a mammoth to be coaxed back to life.
"We have been able to confirm that the cells are able to react after being transplanted to the mouse embryos – even after such a long time – and that there is biological activity," he added. "Scientists at the university have been working on this project for more than 20 years now and we have made some good progress, but this is a major development," he said. Of the several dozen specimens, five showed the biological reactions that are required immediately before cell division can begin, Professor Kei Miyamoto, a member of the study team at Kindai University, in central Japan, told DW.
