The movie Jurassic Park It becomes a reality. The company Colossal Laboratories and Biosciences has used the genetic edition to create Mouses with mammoth hair. This demonstrates that your techniques to deduce the mammoth, are valid.
Colossal Laboratories and Biosciences not only wants me to The mammoth returns to life in 2028. Its objective is also to deduce the dodo and the Tasmania tiger. All of them species annihilated by the human being, not by natural extinction.
These Lanudos mice They demonstrate the validity of their technology. But one thing is to add a few genes to a mouse, and a very different one, return life to a complete mammoth … How will it do it?
Mammoths running for Siberia in 2028
As explained by the magazine Timethe work consists in identifying the genes responsible for the features that separate the mammoth from the Asian elephant, its closest evolutionary relative.
Then a stem cell of the elephant is edited with Crispr, integrating those genes. That stem cell is inserted into the elephant embryo, which in turn is implanted in the uterus of an elephant, so that it is geste.
An alternative is to integrate these mammoth genes into the zygote of a newly conceived Asian elephant. Colossal will use the two techniques.
But one thing is the theory, and another to carry it out. The big problem is that this technique demands Hundreds of test and error tests to identify correct mammoth genes that define their essence, and only the results can be known when the genetically modified elephant is born.
The gestation of an Asian elephant lasts 22 months, so those tests would last decades. It is also an endangered species, so you cannot experience with it.
The solution for almost everything in science is resort to mice. They are very studied and their gestation lasts 20 days, so quick results are obtained.
That is what colossal has done: it has identified the mammoth genes that manage hair production, their color, and their lanest appearance, and have inserted them into a mouse stem cell.
It must be said that this attempt at de -sexyt is possible, because many have been found intact mammoth remains preserved in Siberia’s iceincluding meat and blood. It is also an animal that was extinguished relatively recently, between 12,000 and 30,000 years. So intact genetic material is preserved.
Colossal scientists produced almost 250 embryos and extracted between 200 and 300 cells, which were implanted in the uterus of a dozen mouse females. 38 mouse offspring were born, and they all had the mammoth tanning and curly hair, as well as its accelerated lipid metabolism.
“The Lanudo mouse project does not bring us closer to the mammoth, but validates the work we are doing on the way to the mammoth,” explains the CEO of Colossal, Ben Lamm, in Time.
The first step is already taken, but there is still a lot to identify and successfully implement the rest of the genotypes that record the essence of a species.
Surely We will see more mice with other mammoth features. Only when they have tried all the features, they will take the step to implement it in Asian elephant cells.
Colossal defends its techniques of Dextinctionbecause human action, including its contribution to climate change, will be extinct to Between 35 and 50% of all species on earth From here to 2050. And this lack of diversity will also extinguish medications and materials that are extracted from animals and plants.
The first step to return to life an extinct animal has already been given: Lanudos mice with mammoth genes. The following will be the Dodo and Tigre of Tasmania. Will we see them again one day running free?
