Woolly mammoth to be brought back to life from cloned bone marrow 'within five years'
Scientists believe it may be possible to clone a woolly mammoth within five years after finding well-preserved bone marrow in a thigh bone recovered from permafrost soil in Siberia.
Teams from Russia's Sakha Republic's mammoth museum and Japan's Kinki University will launch fully-fledged joint research next year aiming to recreate the giant mammal, Japan's Kyodo News reported from Yakutsk, Russia.
By replacing the nuclei of egg cells from an elephant with those taken from the mammoth's marrow cells, embryos with mammoth DNA can be produced, Kyodo said, citing the researchers.
Securing nuclei with an undamaged gene is essential for the nucleus transplantation technique, it said.
For scientists involved in the research since the late 1990s, finding nuclei with undamaged mammoth genes has been a challenge.
Mammoths became extinct about 10,000 years ago.
But the discovery in August in Siberia has increased the chances of a successful cloning.
Global warming has thawed ground in eastern Russia that is usually almost permanently frozen, leading to the discoveries of a number of frozen mammoths, the report said.
