Stem cell hope for endangered species

IN a move closely resembling the plot of the movie Jurassic Park, a San Diego zoo plans to use the frozen cells of dead animals in an attempt to bring endangered species back from the brink of extinction.

San Diego’s Frozen Zoo, a 213-acre habitat that resembles the African savannah, stores cells of endangered species such as the white rhino, but it’s a controversial procedure that hasn’t yielded optimal results.

While the process is being used on endangered species, it would be technically possible to use it for extinct animals, using surrogate mothers from other species.
