In its race to advance assisted reproduction and stem cell associated technologies to save the northern white rhinoceros from extinction, researchers announce a major breakthrough: the creation of primordial germ cell-like cells (PGCLSs) from induced pluripotent stem cells of the northern white rhino Nabire. Now there is one last step to master for the production of artificial rhino gametes (eggs and sperm) from preserved tissue. If successful, this would boost the availability and genetic diversity of embryos and become a cornerstone for saving the northern white rhinoceros.
