It has been 22 years since scientists managed to clone the first mammal (RIP Dolly the Sheep) and more than a century after cloning a sea urchin. Since then, cloning has turned into pigs, goats and even dead pets, but scientists do not stop there. According to recent reports, Russian and South Korean researchers want to clone a species of extinct horse with the help of DNA extracted from a 40,000-year-old colt. If all goes according to plan, not only will they have resuscitated the little dead horse for a long time, but they will be even closer to the ultimate goal: to bring back the woolly mammoth.
The preserved horse (Lenskaya), found 30 meters deep in Siberian permafrost last month, would only have 20 days when he died and entered his icy grave, a crater known as the 'mouth of hell' Or in the world of hell. The horse's body was completely intact to the hair and hooves, which made the tissue samples much easier. Hwang Woo Suk, a leading researcher at the Seoul University of Stem Cells and a former professor at the Seoul National University, joined the project to oversee the extraction of blood. DNA for the cloning process. "We are trying to make a primary crop using this baby horse," said Suk. "If we get living cells from this ancient baby horse, it's a wonderful promise for people in terms of cloning." Researchers say that modern horses are very close to the old Lena horse. embryo in a carrier woman instead of cultivating it inside a laboratory.
Scientists have been working on the woolly mammoth DNA fusion with that of an elephant in laboratory environments, but the dream is to implant a hybrid embryo inside of the lab. a living elephant. A victory in the extinct horse trials could be the key they were looking for to make this Pleistocene park work.
