Friday, 14 February, 2003, 20:28 GMT. Dolly the sheep clone dies young. Dolly the Sheep was born in 1996. Dolly the sheep, who became famous as the first mammal to be cloned from an adult cell, has died. The news was confirmed on Friday by the Roslin Institute, the Scottish research centre which created her.
It developed into an embryo, which was implanted into a surrogate mother and carried to term. (The transfer step is most often done using an electrical current to fuse the membranes of the egg and the somatic cell.) The lamb, Dolly, was an exact genetic replica of the adult female sheep that donated the somatic cell.
