Dolly the Sheep didn’t just make headlines around the world – she influenced research here at the University of Edinburgh and worldwide in the areas of genetically modified livestock and stem cell research.

Check out the links below for Plain English summaries of some of the most important research papers from before and after Dolly.

Cloning before Dolly – frogs are cloned from specialised cells

Dolly the Sheep is announced to the world – the world’s first animal cloned from an adult cell

Stem cells after Dolly – induced pluripotent stem (iPS) cells are created using adult cells

Cloning after Dolly – Nottingham “Dollies” show cloned sheep age normally
