Can Stem Cells Help Save Endangered Species?

Scientists found there may be hope for endangered species through stem cell transplants and test-tube animals.

Stem cell research just got a little bit cooler. In a new study, scientists have created artificial stem cells from two of the most endangered species in the world: the northern white rhino and a west African monkey called “the drill.” In a last-ditch effort to help them survive, scientists “re-programmed” skin cells with biological tools like retroviruses to make them "pluripotent." That means they can be turned into more specialized cells like neurons or cartilage to replace malfunctioning ones in sick or diseased animals. And if the stem cells can be turned into egg and sperm cells, it may be possible to create embryos with new genetic combinations instead of simply reproducing existing animals through cloning. Now, the research team is trying to duplicate their success with 10 other endangered animals. At least one of them rhymes with shmelephant.
