For some extra context, Dolly was not made using the iPSC approach (reversing differentiation from adult cells). Dolly was cloned using a process called Somatic Cell Nuclear Transfer, where the nucleus of an adult cell is placed inside an embryo, replacing the embryo's nucleus. The embryo then develops using the DNA of the individual that donated the nucleus.
The article kind of alludes poorly to this, but somatic cell nuclear transfer (developed by John Durdon) was a huge milestone in the field that eventually led to Yamanaka's discovery of the pluripotency factors, for which they both won the Nobel prize in 2012.
