Stem cells show promise in saving rhinos

CALIFORNIA: The San Diego Zoo and scientists at The Scripps Research Institute report significant progress in resurrecting a nearly extinct species of rhinoceros, perhaps within 10 to 20 years.

In a new study awaiting publication, the team said they have made artificial embryonic stem cells from the frozen tissue of four northern white rhinos, raising the total to five. Frozen tissue from seven other rhinos have yet to be converted into these artificial stem cells, which can produce nearly any cell in the body.
