Only seven Northern White Rhino’s are left on the earth. A dire situation for the armored survivor after decades of hunting, poaching, and habitat loss. A low reproduction rate is threatening extinction for one of the world’s largest mammals. Advances in stem cell research are hoping to save and reintroduce Northtern White Rhino genetic samples to preserve the species. There’s even a “stem cell zoo”. A place to save cells from all types of animals for current and future research.
