A unique fossil, liquid blood in the body of a 42-year-old dowry
MOSCOW (Reuters) - Scientists from a Russian-Japanese scientific mission have found liquid blood in blood vessels to reverse the body of a frozen dowry 42,000 years ago and have confirmed it is the oldest blood ever found in the world.
The mission found the frozen dowry in 2018 in a wall of a karstic crater about 90 meters deep in the Siberian frost soil at Batagai low in Yakutia.
The scholars began to study the dowry at the same site, and then transferred to the Museum of the Russian North-Eastern Federal University.
Scientists are now trying to reproduce the dowry, after extracting the cells from the old dowry. The team hopes the experiment will succeed and exploit its results in the reproduction of mammoths and other extinct species in the future through the frozen material in the frosty soil.
The study revealed that the dowry was in exceptional condition without any obvious damage, and that his hair was on his head, legs and part of his body. All the ancient horses were found without hair, and the scientists found that the dowry was newly born. Or two at most.
"The anatomy revealed that all internal members of the dowry were in good condition, and samples of liquid blood were obtained from the vessels of the heart. The muscle tissue retained its original red color," said Simon Grigoriev, head of the mammoth museum in the Russian city of Yakutsk.
He pointed out that the dowry - dating back to prehistoric times - died drowning when he was less than two weeks old.
"Now we can say that this is the best animal ever kept in the Ice Age, which is very rare for the old discoveries, because some of them are either incomplete or fragmented or have many deformities."
The unique dowry will become one of the major exhibits at the Mammoth Show in Japan for a year, which will start in June this year.
Are confident of success
This fossil has raised hopes for the cloning of ancient prehistoric horses and the return of extinct species to life.
After months of intensive joint work by the Yakutian University team and scientists from the South Korean biotech research firm Swam, scientists have indicated that they are "confident of success" in extracting cells from this dowry in order to reproduce its species and bring it back to life.
The joint South Korean-Russian research team led by Professor Huang Woo-suk, a South Korean cloning expert, has become optimistic that he will get the cells needed to try to reproduce the extinct Lenskaya strain, which was extinct some 4,000 years ago.
"Attempts will continue until the end of April this year," said a source at the University of North East in Yakutsk (the world's coldest city), which hosts the work.
"There are seven researchers involved in the project, and the first clone attempt is likely to use Korea's horse as an alternative mother used in cloning earlier, and the Korean horse is also very old," said Dr. Lina Grigoriva, a Russian researcher at the project.
"We hope the world will soon meet the clone of the old clone, which lived 42,000 years ago," said the media chief of the Russian Northern Federal University, Michael Yakovlev.
