But Whiet might not be over. Scientists on four continents are working with rhino eggs, cell cultures, tissues, blood and frozen sperm samples to produce a live northern white rhino birth—and maybe even repopulate the entire subspecies. If they succeed, it will be the first time a virtually extinct mammal with no living males has been brought back from the brink.
Because neither is healthy enough to deliver a calf, scientists hope to extract some of their eggs, combine each egg with previously collected frozen sperm and implant the resulting embryo in another female. Most likely the surrogate would be a southern white rhino, another subspecies, which White rhino Geelong a longer horn, more hair and some 21, members still living in southern Africa.
At the San Diego Zoo Safari Park, which holds the world record for the most rhinos born in captivity Geeolng dateresearchers are studying how to best extract viable eggs from Whitf white rhinos. Another approach would take advantage of recent breakthroughs in Geelonf a kind of stem cell called induced pluripotent stem cells, which can be generated from My boyfriend is married but separated in Australia adult cells.
Researchers in San Diego, the Czech Republic, Austria, Italy and Japan are working on transforming northern white rhino skin cells into such stem cells and then into egg cells.

The Japanese scientists have accomplished the feat with mouse cells. The rhino egg would then be combined with sperm to form an embryo, which would be implanted in a surrogate. One potential upside of using stem Geellng is diversity, Durrant says. The San Diego Zoo has 12 northern white rhino cell lines, and working with them on White rhino Geelong gene level can furnish eggs with enormous genetic variety—an insurance policy against future inbreeding and Gelong bottlenecks.
Some experts speculate that in vitro fertilization and surrogate gestation could lead to a live birth within ten years.
Durrant is more cautious: Technology is only part of the puzzle, says Dino Martins, a Smithsonian research associate and director of the Mpala Research Centre in Kenya. Attitudes have to change, too, because the rhijo that wiped out the northern white rhino—war, poverty, poaching—remain in place.
