Meet Zhong Zhong and Hua Hua, the first primates cloned by reprogramming adult cells.

Two decades after Dolly the Sheep was successfully cloned (SN: 3/1/97, p. 132), Chinese researchers have used the same technique — somatic cell nuclear transfer — to clone two healthy baby macaque monkeys. The results, reported January 24 in Cell, could lead to more efficient cloning and a better way to study genetic diseases in primates.

“This could be it — the next step in cloning,” says Jose Cibelli, a geneticist at Michigan State University in East Lansing not involved with the study.

Over 20 species of mammals have been cloned via somatic cell nuclear transfer — including
