World's first Wild Artic Wolf cloned

Donor cells were extracted from the skin of a wild female arctic wolf imported from Canada to Harbin Polarland. It received its oocyte from a female dog, and its surrogate mother was a beagle.

Important information

  • A Beijing-based gene company has succeeded in cloning the Arctic Wolf in order to save the endangered species from extinction.
  • Maya, which means "excellent health," was given to the freshly cloned wolf.
  • The wolf's donor cell originated from a skin sample of a wild female Arctic Wolf. It acquired its oocyte from a dog.
  • Cloning required the creation of 137 new embryos from enucleated (removal of the nucleus from the cell) oocytes and somatic cells.
  • Seven beagles' uteri were implanted with 85 embryos.
  • The beagle was chosen as the surrogate mother since this canine breed has genetic connection with the prehistoric wolf.

What exactly is cloning?

The act of creating a genetically identical duplicate of a cell or organism Cloning occurs often in nature, for example, when a cell repeats itself asexually with no genetic changes or recombination. Bacteria and other prokaryotic organisms (organisms without a cell nucleus) use binary fission or budding to generate genetically identical replicas of themselves. All cells that undergo mitosis, such as skin cells and cells lining the gastrointestinal system, are clones in eukaryotic creatures (organisms with a cell nucleus) such as humans; the only exceptions are gametes (eggs and sperm), which undergo meiosis and genetic recombination.

The Arctic Wolf

Mammal. The Arctic wolf is a grey wolf subspecies (Canis lupus). Arctic wolves live in among of the world's most hostile environments, where the air temperature seldom climbs beyond -30 degrees Celsius (-22 degrees Fahrenheit) and the ground is continuously frozen. They are one of the few mammal species that can withstand these extreme environments. Arctic wolves are typically smaller than grey wolves, with smaller ears, somewhat shorter muzzles, and shorter legs to protect themselves from the cold air. They normally live alone or in groups of 6 wolves and are entirely white with a thick, insulating coat.
