Russian researcher Sergei Zimov is building a vast 160 sq km "Pleistocene Park" in northeastern Siberia near Alaska. He hopes to one day populate it with wooly mammoths and sabertooth tigers.  (Source: BBC News)
By injecting DNA sequenced from an extinct species into a mouse embryo, scientist have delivered a proof-of-concept, which could one day lead to full cloning of long-extinct species

Cloning extinct species has been a long standing dream of mankind.  Well, long standing since the 90s at least, when the movie Jurassic Park stole the imagination of audiences worldwide with a fictitious story in which scientists use DNA extracted from long dead dinosaurs to resurrect the beast through cloning (with disastrous results).  Since the movie, cloning science has advanced at a steady pace, and there has been increasing interest within the scientific community in cloning extinct creatures.

While it seems unlikely that dinosaur DNA pristine enough to produce a full genome map would ever be found, it would be reasonably easy to sequence other extinct creatures genomes such as the dodo, Neanderthals, wooly mammoths, and other more recent critters which researchers have recovered soft tissue samples (bone marrow, skin, etc) from.  However, such dreams were often scoffed at and remained the realm of pseudoscience.

They were derided -- until now.  In an exciting, successful new experiment, researchers at the University of Melbourne report that they have taken DNA from the extinct thylacine, commonly known as the Tasmanian tiger, and inserted it into a mouse embryo which continued to grow with the thylacine gene in place.  The process represented the first time DNA from an extinct creature was inserted into an embryo, effectively bringing "back to life" in part the extinct species.

Dr Andrew Pask, who led the research, says the experiment was the first time DNA from an extinct species has been successfully used "to induce a functional response in another living organism".  Professor Marilyn Renfree, a member of the team, states, "For those species that have already become extinct, our method shows that access to their genetic biodiversity may not be completely lost."

The findings of the team will be reported in the international science journal PLoS ONE this week. 

The Tasmanian tiger, whose scientific name is Thylacinus cynocephalus or thylacine for short, is an extinct marsupial from Australia that looked like a wolf.  The last surviving member of the species died in captivity at the Hobart Zoo in 1936.  The gene was extracted from tissue samples of flesh preserved in ethanol, which were donated by the Museum Victoria in Melbourne Australia.  The DNA was verified to be thylacine, and then was injected into the developing mouse embryo.

The gene injected was the thylacine Col2a1 gene, which controls cartilage and bone growth.  The mouse embryo was selected, partially because mice have a similar gene, also labeled Col2a1.

Dean of Science at the University of New South Wales, Mike Archer, is leading a project that aims to fully clone extinct animals, but he warns that success remains far off. He commented on the developments, stating, "The next question then is, well what if you did that with the whole of the DNA of the thylacine?  Could you in fact bring back a thylacine? Technically I think this is pretty difficult at the moment but on the other hand this is one very significant step in that direction and I'm delighted."

Despite the steep challenge, Professor Archer isn't giving up.  He states, "I'm personally convinced this is going to happen. We are working on a number of projects like this. I've got another group working on another extinct Australian animal and we think this is highly probable."

Aside from possibly leading to clones of extinct animals, the breakthrough also may yield scientific gains in biology and medicine.  Professor Richard Behringer, Deputy Head of the Department of Molecular Genetics, M.D. Anderson Cancer Center, at the University of Texas, says, "This research has enormous potential for many applications including the development of new biomedicines and gaining a better understanding of the biology of extinct animals."

Several groups are working to make real life Jurassic Park-style exhibits with cloned animals.  Some like a team in Japan are focusing on finding frozen gametes from ice age animals, while others are focusing on more traditional cloning

Perhaps most ambitious is the Pleistocene Park currently being built in northeast Siberia by Sergei Zimov.  Zimov introduced a grassland ecosystem along with 100 large mammals including
reindeer, horses and moose.  He plans on eventually introducing to the park wooly mammoths, extinct saber tooth tigers and prehistoric bears; all cloned of course.  On the possible threat of cloned tigers he states, "OK, so one or two people will be killed, like in India, but far more will die of alcohol in this place than from tigers."

While Zimov and others have thus far not revived any extinct species, advances in cloning may one day make their dreams a reality.  And with the new Australian breakthrough, that day seems to have come much closer.

They created a chimeric animal, they did not clone an extinct animal. This will have the mitochondrial DNA of a mouse among other things. This is interesting however, in that it is a chimera with one of the animals involved being long extinct.

Not only that, but they only injected a single gene, a homologue to a similar one in mice (which they knocked out for the experiment, obviously). This is a far cry from injecting a whole genome and using it to develop a representative animal. The mouse genome is still there and intact.

The only breakthrough here is that they can now see how the extinct animal's specific gene functioned relative to how the mouse gene functions in the context of the whole mouse genome.

The definition of clone is to create a genetically identical copy of an organism.

1. Biology.
a. a cell, cell product, or organism that is genetically identical to the unit or individual from which it was derived.

This experiment succeeded, if accurately reported by the researchers, in creating a partial genetic copy of an extinct organism's DNA and implanting it into a living organism. Thus whether it has 1 gene or 1,000 genes it IS a partial clone of this extinct animal by the definition of the word.

While obviously it would be incredibly more complex to fully clone an extinct animal (a human has 20k-25k genes), you're missing the big picture here, that this is a significant step, indeed, the first real step towards this.

You gotta take little steps to make big ones.

What is more likely to happen is that our conciousness will be transfered to a data bank, where it will then be able to process thoughts and interact with other stored personalities in a collective. However, the original being (us) will still die. It's like a program that develops, and then is stored, being able to change with time. Like the Matrix the Matrix. At any rate, transference of thoughts to a magnetic/electrical/metallic computer are much more plausible at this point in our techonological advances than transference to a blank biological computer. I imagine that if we ever do "clone" ourselves and live on, we'll somehow lose conciousness during the transfer, as you would have to have live syncing between the old and the new. We'd also still likely store our memories to a non-biological computer first, and then transplant them again from there.

Unless you know of a way to transfer your consciousness into your cloned self, you'll be stuck in your terminal body. And even if it were possible you'd face the ethical question of replacing one persons consciousness with another.

I don't have a problem with cloning animals but once you start messing with human DNA you begin to cheapen human life.

That's akin to running 13 miles and saying "Well, I ran a partial marathon." Did you define up "Partial Clone" or "Clone?"

"Clone" is an all or nothing term. You either are a clone, or you aren't.

The organism in question is two organisms' DNA meshed together. That is not identical to any one organism I know.

This is a great step forward, but it is not a clone of an extinct animal.

So can we clone Polar Bears using mice. No!?

But I want mini polar bears to keep in a small tank in my house. Watch them hunt the goldfish, the mini mice-seals, and drink from the bottle in the corner.

Oddly they used a Mammal in the clone of a marsupial. Wonder the effects of that? especially, when introducing more then one gene. Wonder if the DNA altered mouse would be able to reproduce viable offspring.

One different gene is hardly new for life in general. Organisms mutate all the time. Most mutations don't even affect you. They would have to cherry pick a gene that would do much of anything (which is obviously what occurred).

Hey Jason, do scientists have any theories regarding cloning extinct animals with JUST their DNA? I'm guessing they have some ideas on how to do it without the "somatic cell nuclear transfer" process.

By JasonMick (blog) on 5/20/2008 3:56:03 PM , Rating: 2
Hi 16nm,
A bit confused by your question, but I'll try to field it. Do you mean cloning without a donor cell/embryo? Such an approach would differ greatly from the current thought on how an extinct animal COULD some day be cloned.

The current thought would be to take a genetically and physiologically similar creature, ie for a wooly mammoth an elephant, take a zygote remove all the dna, implant surrogate DNA from the extinct animal, implant mitochondrial dna inside mitochondria, etc.

You do need some sort of base cell. However, eventually this cell might be able to created from scratch

but, that still wouldn't solve the problem of needing a womb at some point for the egg to at least partially develop in (amount of in womb-growth dependent on the Class of the species). Perhaps a synthetic womb could someday be invented, but there's no research that I know of on this.

However, even the basic method I first mentioned remains far away from actualization, and despite this breakthrough a fantasy of sorts. A big tricky spot would be replacing all the mitochondrial dna in the cell.

And the other really hard part is just getting the DNA. Only a few extinct species have had their genome fully sequenced.

And as far as dinosaurs, to quote a good story on cave bear genome sequencing, "Barring some fundamental misunderstanding about the nature of DNA decay, he says it is highly unlikely viable DNA will be recovered from 150 to 200 million year old Jurassic age samples."

Definitely a lot of research going on, but its hard to make partial clones with helpful tools ie. genetically similar surrogate mothers, let alone with some sort of purely synthetic cloning process (currently infeasible).

However, remember, if you know anything about science, you know you can never say never.

"The only true wisdom is in knowing you know nothing."

Yes, that's what I was asking about. It seems like a chicken-and-egg problem to me. A carrier, or womb, of the extinct species would seem to be needed but you can't have that until you've cloned the extinct animal. But, as you say, I guess if somekind of faux womb could be developed then this may be possible. This seems like the greatest complication to me given the complexity of the womb.

Its not that difficult in principle. Cross species surrogates have been done before, I think there has been horse/zebra and cross tiger subspecies (not totally sure). I know Tulane did a pigtail monkey surrogate giving birth to a rhesus monkey (they are thought to be several million years apart on the evolutionary tree)

By fflintstone on 2/11/2010 5:13:24 PM , Rating: 2
The chicken-and-egg question would seem to hint at how this can be done. If you think about it in terms of evolution and mutation, it is obvious that the egg came first -- at some point in time, a thing which was "NotAChicken" laid a mutated egg from which hatched a "Chicken".
For the resurrection process, you would presumably start with something genetically as close as possible to the target animal, then artificially mutate the eggs over a number of generations to arrive at the desired end result.

The definition of clone is to create a genetically identical copy of an organism.

Maybe I missed something, but I don't think the article claims that an identical copy of an organism was created. The Col2a1 gene was cloned, not the Tasmanian tiger as a whole.

Honestly, this article blows the propensity of this achievement way out of proportion. A gene was cloned from one mammal into another...this has been done millions of times by flunkie graduate students around the world. The only significant detail is that one mammal is extinct.

The cloning of a gene into an animal of a distant phyla (from human into housefly for example) while maintaining functionality is a much more exciting accomplishment--which has also been performed countless times.

Dailytech should really keep away from such news, unless there are plans to recruit writers with enough experience in the biological sciences to distinguish milestones from monotony.

This article is blatant sensationalism.

This is simply transfection.

Yes I know.. I took biology and history in college (Etymology of the word).

Though I remember, a chimera is made of multiple zygotes; not one zygote and an infusion of genetically different DNA.

The other cases I can think of that did something like this is the bioluminescence rats, and the altering of immune markers on pigs for human organ harvesting. Both cases used non-extinct animals, this is the first case I have read about, using extinct animals. I'm sure they used the simple, tried and true, transfection to introduce the extinct animal's gene into the mice, but it is still a extinct animal. But if you can make a chimera, you can then find a distant cousin to "replace" the DNA inside the nucleus, allowing the outside RNA/DNA help with making a viable embryo. Maybe..

Ok here are the facts:

They did not clone anything in any way, shape or form.
They sequenced a very small fragment (264 base pairs) from an enhancer element from the proa1(II) collagen gene. They compared the sequence to known sequences in genbank and found it different enough from human and mouse sequences to be sure it was not an artifact. They made a reporter gene construct basically an enzyme that can provide a blue staining of the tissues it’s expressed in under the regulation of this enhancer element. They created a transgenic mouse with it and observed the "stain" was only where it was expected to be. It is really only a proof that the DNA was in good shape and that there was no PCR artifacts when they amplified it for sequencing. Who knows if other animals that have never been sequenced (either different species or even individuals) could have this sequence naturally. The gene was chosen because it is VERY highly conserved. Its stretching it a bit to even say they produced chimeric cells, definitely not cloning. I’ve made dozens of transgenic animals and I would not say they were Human/Mouse chimeras (although some would I guess) and No one I know of would say it’s a step towards cloning a human. Rather than a chimeric cell it’s really closer to a somatic cell hybrid (although that is the fusion of two genomes in one cell. I respect Richard Behringer, he is an important person in transgenics but this is really FAR more flash than substance.

Animal behaviour is both innate (genetic) and taught by parent animals. It may not be possible to replicate their old behaviour depending on the environment.

True, but if you plan things out properly and start a comitted program to get these things in the wild then a good first step would be creating or selecting a natural park that matches as closely as possible the natural habitat of the animal. Once you've done that you start cloning from as much differing genetic examples of the animal that you have on hand and work on getting them released into the park.

Once you can get them successfully hunting, the rest of their natural behaviour should start coming back, perhaps not all at once but over time.

Perhaps I can explain it better. At least, I think I get it...

You have a gene. You have a similar gene of a modern animal. You replace the gene with the extinct animal's gene. This is what was just done.

Now, if you want to clone an animal you have to do more than one gene. You have to replace many genes. Many genes together form RNA. RNA aligned into strings is called DNA.

You would then implant the DNA into the nucleus of an embryonic cell of the physically similar animal you're using to clone the extinct animal.

The embryonic cell multiplies itself until it becomes a fetus, and is then carried to term by the modern day implanted creature.

I didn't go looking this all up on Wiki or anything, so if there are any biologists here please correct me if I'm wrong on anything.

Cloning living species. As of now, was there really a truly successful clone of an existing species? The sheep that was cloned died much sooner than it should have. And Pandas are on the verge of extinction, they may have 50 yrs left before they're all gone.

While I marvel at these new sciences and discoveries, what about just getting the roots done first before expanding onto other sci-fi tangents? This taz rat tiger, will never be a true taz tiger, we have a chance now to save current species, but there's almost no real progress in it. Going back to Pandas, out of all the Pandas in captivity, none of the off springs have survived. The one that did, and they let into the wild died, because it did not know how to live in the wild, coming from captivity.

As for human cloning. Don't, just don't. There's no need for it, even to clone a historical figure, it won't be the same person, you can't take a dead soul and grab it's brain or memories, and put it into a new body. And those that died centuries ago were geniuses are completely out of touch with today's thinking and probably can not adapt. It's not the movies, one does not come from the past and just adjust, I work with people in their 50's who still don't know how to program a VCR or Tivo.

Human cloning is just not something natural. If I were given a chance to be immortal, or death, I'll chose death, there's no need for me to be alive forever, I welcome it when my time comes, and what's the use of being 100+ yrs old, and have people wipe your behind when you're done doing number 2. If I can't take a shower, use the toilet, or feed myself. Then please, let me die, don't pump me full of meds, just to have me be alive for no useful reason. I can no longer contribute to society, there is no more need for me.

Personally, I hope I go gracefully in my 70's I get bored sitting and watching TV/Movies all day long. There was one period of my life I quit my job, and did nothing for 6 months, after the 2nd month I got bored, parties became monotenous, hanging out with my friends every night in bars got boring, sitting at my computer became unfun. I did everything I wanted outside traveling and seeing the world in those 6 months and well, decided to go back to work. And this was in my mid 20's, so yeah, I had fun, lived it large, but after a while, I just had way too much time on my hands.

Really cloning is nothing new. If you except the fact that a clone is not 100% the same creature (different body, different brain, different life). The Bible talks about cloning very early on:
From chapter 2 Genesis:
21 And the LORD God caused a deep sleep to fall upon Adam, and he slept: and he took one of his ribs, and closed up the flesh instead thereof;
22 And the rib, which the LORD God had taken from man, made he a woman, and brought her unto the man.
23 And Adam said, This is now bone of my bones, and flesh of my flesh: she shall be called Woman, because she was taken out of Man.

My understanding is that bone marrow is the best source for DNA. Add to that, Gods understanding of DNA well enough to make a male and clone from him a female. It always amazes me when science and the Bible talk about the same subject, when the Science side finally gets it correct, it always matches the Bible. Bible of course explains things in simplified terms, Moses and the others where just leaders of men not scientist....They would not understand DNA, Molecules, and other things. So, God had to explain it to man as we would explain something complex to a child.

Believe in God and the Bible or not; it is still something you have to think about....

Surely when an animal becomes extinct its part of the evolution cycle of earth. Once they are gone they should remain so and let other species take their place. If they need to make medical advances in this way why not just use existing animals, sheep, cows, pigs etc...

I have to say this feels like the film The Island.

Anyone else but me think that photo of Sergei Zimov in the article looks like it's been photoshopped? His head looks way too large for his body.

wow just wow.
This is amazing news, although i'm higlhy against any kind of cloning I actually like the idea of bringing extinct animals or more exciting dinosaurs to life once again!

Thylacine reproduction

To actually bring a Thylacine to term they will need a compatible species - is there one? The only marsupial of comparable size that I can think of would be the kangaroo, which would be rather cruel.
