Ian Wilmut. British embryologist Dr. Ian Wilmut, head of the research team who cloned "Dolly" the world's first sheep cloned from an adult cell. His research was conducted at the Roslin Institute in Edinburgh, Scotland. Wilmut's work involved taking an egg cell from a Scottish Blackface (SB) ewe and removing the cell nucleus. Next, an adult cell from the udder of a 6-year-old Finn Dorset ewe was cultured and then injected into the enucleated egg cell. A spark of electricity fused the udder cell with the egg cytoplasm and stimulated the egg to grow into an embryo in the womb of a surrogate SB sheep. In 1997, Wilmut introduced to the world "Dolly", the first sheep to be cloned in this way.
