Live Mammoth Cells?





The plausibility of restoring the mammoth has just become completelyconvincing. These are not inexperienced eyeballs and way moreimportant, having the content of a defined cell that is intactclearly opens the door for outright cloning using an elephant egg. Somehow or the other it is going to be done and actually done often.
The idea that the cell is actually alive does begger our imagination,but we have restored living plant cells already, so why not?
The point is that we are on the way to having baby mammoths andshortly thereafter the hunt will be on for the whole Pleistocenemenagerie. It will be very exciting to watch.

A team ofpaleontologists said they have found “living” mammoth cells inremains discovered in the Far East that could be used to clone theancient mammal.

But some scientistsexpressed skepticism regarding the find, saying they doubted livingcells had been found and questioned why such a significant discoveryhad not been announced in a scientific journal.

A hundredmeters under the permafrost in the Ust-Yansky district of Sakha, aninternational expedition called Yana-2012 found soft tissue, fattytissue, fur and bone marrow of mammoths, expedition leader andNortheast Federal University researcher Semyon Grigoryev said Friday,according to a news report posted on the university's website.


Head of theKorean Sooam Biotech fund Huang Vu-Souk said the “living” cellsthat were found could be used for cloning, the news report said. Anunidentified member of the expedition team said findings from theexpedition would be published in authoritative scientific journals.


A scientistfrom the Institute of Paleontology at the Russian Academy of Sciencessaid he doubted that living cells, which he described as emittingcarbon dioxide and processing nutrients, had been found so deep inthe permafrost.


“Thus farthere haven't been truly living cells in any of the mammoths [found]— a complete DNA sequence has not even been able to be obtained,”head of the mammals laboratory at the Institute of PaleontologyAlexander Agadzhanyan told RIA-Novosti.


Agadzhanyan'scolleague at the Institute of Paleontology Alexander Markov told thenews agency that in serious scientific practice, such majordiscoveries are announced not in the media but in research journals.


NortheastFederal University is studying the genome of ancient animals under anagreement signed earlier this year with the South Korean Center forBiotechnical Research. One of the project's central tasks is cloninga mammoth.


Remains ofmammoths, which went extinct about 4,500 years ago, are occasionallyfound in the permafrost of Russia's northern regions.


Earlier thisyear, a team of Russian scientists led by a researcher from theRussian Academy of Sciences conducted a groundbreaking experiment inwhich they produced an entire plant from fruit tissues found in thepermafrost. The scientists said the experiment opened the door to theresurrection of other ancient species.
