According to the World Wildlife Fund (WWF), the name. As of February 2022, there are a total of fourteen northern white rhino embryos created, 11 from eggs from Fatu inseminated by sperm from Suni and 3 inseminated by sperm from Angalifu. Northern White Rhinos Aren’t White Contrary to their name, northern white rhinos are more of a dark grey color than white. In December 2020, 14 egg cells were retrieved from Fatu eight of them were fertilised by the sperm of the dead northern white rhino Suni, resulting in two viable embryos. In January 2020, it was announced that "another embryo" was created using the same techniques all three embryos are "from Fatu", until they can be placed into a surrogate mother, probably a southern white rhino. In September 2019, scientists announced that they fertilized in vitro the eggs with frozen sperm taken from dead males two of the resulting embryos were viable. In August 2019, ten egg cells (five from Najin and five from Fatu) were harvested to be artificially inseminated with the frozen sperm of a northern white rhino as part of a project by the Leibniz Institute for Zoo and Wildlife Research, Dvůr Králové Zoo, Kenya Wildlife Service, and Avantea. Within four years, a northern white rhino could be born from the embryo method, says Stejskal. The DNA of a dozen northern white rhinos has been preserved in genetic banks in Berlin and San Diego. His associates in Italy have been able to make embryos and now they are fine-tuning how to. Subsequently, in the future, it might be possible to specifically mature the cells into specific cells such as neurons and muscle cells, in a similar way in which Katsuhiko Hayashi has grown mouse oocytes out of simple skin cells. Within four years, a northern white rhino could be born from the embryo method, says Stejskal. At the end of 2015, scientists from the Leibniz Institute for Zoo and Wildlife Research, San Diego Zoo Global, Tiergarten Schönbrunn, and Dvůr Králové Zoo developed a plan to reproduce northern white rhinos using natural gametes of the living rhinos and induced pluripotent stem cells.
