Woolly Mammoth On Verge of Resurrection, Scientists Reveal (theguardian.com) 169
An anonymous reader quotes a report from The Guardian: The woolly mammoth vanished from the Earth 4,000 years ago, but now scientists say they are on the brink of resurrecting the ancient beast in a revised form, through an ambitious feat of genetic engineering. Speaking ahead of the American Association for the Advancement of Science (AAAS) annual meeting in Boston this week, the scientist leading the "de-extinction" effort said the Harvard team is just two years away from creating a hybrid embryo, in which mammoth traits would be programmed into an Asian elephant. "Our aim is to produce a hybrid elephant-mammoth embryo," said Prof George Church. "Actually, it would be more like an elephant with a number of mammoth traits. We're not there yet, but it could happen in a couple of years." The creature, sometimes referred to as a "mammophant," would be partly elephant, but with features such as small ears, subcutaneous fat, long shaggy hair and cold-adapted blood. The mammoth genes for these traits are spliced into the elephant DNA using the powerful gene-editing tool, Crispr. Until now, the team have stopped at the cell stage, but are now moving towards creating embryos -- although, they said that it would be many years before any serious attempt at producing a living creature.

It is possible that they don't have the complete, undamaged mammoth DNA. Also, the cellular organs and other parts do have to come somewhere, or recreated. That is the amazing part of the cellular theory: all current life is a continuum from the first cell. It would be interesting to have an artificial uterus with all the roles of viruses, hormones and others factors replicated, but as of now it probably doesn't exist.

The technique they are using — CRISPR — is what we just discussed [slashdot.org] as applicable to humans.

As others have already said, we don't really have a whole, undamaged genome for a mammoth, but an artificial uterus is technologically still very far beyond our capabilities. The only option is to implant the fetus in an existing animal, in which case there may be compatibility issues - the fetus has to be a reasonably close match to the mother, immunologically speaking. A hybrid may be close enough for it to be feasible, and perhaps it is possible to get closer and closer to 100% mammoth by adding more and more for each generation, who knows.
