Reproductive cloning of animals uses a process called somatic cell nuclear transfer.

The idea was to use a technology that didn’t exist when the zoo had stored the samples: somatic cell nuclear transfer.

And it all began with Dolly the sheep: she was cloned in 1996 using a method called somatic cell nuclear transfer.

In 1996, Dolly the sheep became the first mammal cloned using a technique called somatic cell nuclear transfer.

The cloned macaque monkeys are the latest application of a test-tube technique called somatic cell nuclear transfer pioneered 20 years ago with the creation of the cloned sheep named Dolly.
