Ebene News – United States – Elizabeth Ann the black-footed ferret is the first endangered U cloned

Black-footed ferret was born in December after being created from cells over 30 years old

Scientists introduce black-footed ferret to the world named Elizabeth Ann – the very first endangered U species to be cloned

Elizabeth Ann was born on December 10 after being created from the frozen cells of another black-footed ferret named Willa, who died over 30 years ago, according to the US Department of Fisheries and Fisheries. fauna

Once thought to be completely extinct, a small population of blacklegged ferrets – one of North America’s rarest land mammals – was discovered in 1981 by a breeder in Wyoming

Although the Wyoming Game & Fish Department managed to capture more than a dozen blacklegged ferrets, the population had “limited genetic diversity,” which would make any potential offspring “more vulnerable to disease and abnormalities. genetics”

Elizabeth Ann’s story really began in 1988, when the Wyoming Department sent frozen cell samples from a black-footed ferret named Willa to the frozen San Diego Zoo Global Zoo

Subsequent genetic studies showed that Willa’s samples “had three times as many unique variations as the living population”

In 2013, the Fish and Wildlife Service began working with Revive & Restore, an organization that focuses on using biotechnology to help strengthen conservation efforts

Then in 2018, Revive & Restore received the “very first recovery license for research into the cloning of an endangered species”, and they partnered with ViaGen Pets & Equine to successfully create embryos from frozen blacklegged ferret cells and implant them into a substitute

Although the whole process took years, scientists didn’t have to wait long for Elizabeth Ann to arrive

Just two weeks after starting their first Halloween trial, scientists confirmed the surrogate was pregnant – and on December 10, Elizabeth Ann arrived by caesarean, according to the New York Times

As for Elizabeth Ann’s future, she will live the rest of her life at the Colorado Ferret Conservation Center – and I hope she adds cloned siblings and friends to her family

“The frozen San Diego Zoo Global was established over 40 years ago in the hope that it would provide solutions to future conservation challenges,” said Oliver Ryder, director of conservation genetics at the San Diego Zoo Global, in a press release “We are delighted to have been able to cryobank and, years later, provide viable cell cultures for this revolutionary project.”

“It was a commitment to seeing this species survive that led to Elizabeth Ann’s successful birth. Seeing her now in full swing ushers in a new era for her species and for conservation-dependent species everywhere,” a added Ryan Phelan, Executive Director of Revive & Restore “It is a victory for biodiversity and for genetic rescue”
