Russo-Japanese team of scientists from the Museum of the mammoth in the Sakha Republic and Japan Kinki University is going to conduct an experiment century next year they will start cloning the giant mammal, whose remains were found in the Siberian permafrost. Researchers rely on the successful outcome of the operation, and they have to have this foundation. In finding the femur is well preserved mammoth bone marrow, which will become the source of genetic material for the reconstruction of a prehistoric animal.
First, the core of the bone marrow cells placed in a mammoth egg and elephant can get embryos with mammoth DNA. Then these embryos are transplanted into the uterus of a female elephant as it is closely related species. And to see a healthy baby mammoth, scientists plan within five years.
This technology was developed by a research team of Japanese government Institute of Natural Sciences in Kobe and has already demonstrated its effectiveness. For example, in 2008 the way was cloned mouse, who died 16 years before his second birthday.
Research on cloning mammoths underway since the late 1990s., But still could not bring biologists ambitious plans into reality. Cores are needed for transplant cells with intact genes, but to get such core was a big problem, because due to a long stay in the ice of the bone marrow from the remains of mammoths was not fit for use as a biologically active material. However, the latest discovery has been hailed as a major scientific success.
The remains of a mammoth were found in August this year during excavations near the village Batagai in northern Yakutia. Found femur belongs animal height of about 3.5 meters. Nakhodka conventionally dated the thirteenth century BCE.
