The last ones in the wild were observed more than a decade ago in Congo's Garamba National Park, a frequent target of well-armed poachers. Both animals are infertile.
According to a paper published on Wednesday in the journal Nature Communications, researchers have succeeded in creating embryos using frozen northern white rhino sperm and eggs from a southern white rhino, a closely related sub-species. The next step will need to take the eggs of the two last females of the Northern white Rhino and create a clean embryos of the Northern white Rhino.
It is possible that in the future, a female that's a hybrid of the northern and southern rhinos could carry a fully northern white rhino baby to term.
The team was able to extract 13 eggs from 12 female southern white rhinos. A hybrid calf ensures some genetic continuity for the northern white rhino even after its extinction.
Stuart Pimm of Duke University says, 'This is a very ambitious, very courageous last-ditch effort to save some of the genetics of a spectacular animal'.
The next challenge was to achieve fertilization in the lab with frozen semen collected from three northern white rhino bulls.
Using IVF, they hope to see the first northern white calf born within the next three years.
The researchers had to contend with poor-quality sperm.
Richard Kock, a conservationist at Britain's Royal Veterinary College, said: I have no doubt that its purely scientific merit is laudable and it might have some application to endangered species conservation in the future, but I am afraid it is very much Nero fiddling after Rome is burning with respect to (northern) white rhino.
The last hopes were pinned on four white rhinos.
More human remains found at home linked to Bruce McArthur Dickinson is one of more than a dozen officers now working the McArthur case, and has been tapped to eventually testify during Mr. Idsinga said identifying the newly discovered remains could take months depending on their condition and the testing required.
Hamas apps target phones, Israel says If the soldier opens the link, a warning pops up, and they have to meet their commanding officers to debrief on online security. All applications had between 400 to 500 downloads before being removed from the Google App store.
Collecting unfertilized eggs is a harrowing business.
The embryos are viable and "beautiful", Wildt said.
In vitro fertilization is used in the cattle industry to breed more robust herds, and a Cape buffalo was conceived through IVF for the first time in 2016.
The team was able to adapts the reproductive techniques used with horses for rhinos. They also envisioned to bringing already extinct species back from the dead.
The IVF method could offer a way of saving valuable genes from a sub-species that is nearly extinct such as the last male northern white rhino- Sudan which died earlier this year aged 45.
It was the eggs that were more hard to collect. Professor Renfree says the key to the project was new technology developed by Professor Thomas Hildebrandt, who's based at the Leibniz-Institut in Berlin, that for the first time allowed collection of eggs from the ovaries of rhinoceroses.
One of Hildebrandt's co-authors is Kyushu University's Katsuhiko Hayashi, a pioneering reproductive biologist who helped turn mouse skin cells into eggs into living mice.
That is why scientists, alongside with artificial reproduction methods, also work on stem cells development derived from the stem cells obtained from the northern white rhinoceros that have been preserved in the past.
All of the scientists who spoke with The WashingtonPost agreed that biological techniques can complement boots-on-the-ground rhinoceros protection. "But we are extremely confident we can get the [eggs] out". "No species has ever been saved by the high-tech approach alone".
"We should be working on all fronts", Roth said. But Hildebrandt said, "The northern white rhino didn't fail in evolution".
