Ian Wilmut (1944- ),the British embryologist who worked with Keith Campbell to create Dolly the sheep,the first animal cloned from an adult cell. He conducted this research at the Roslin Institute in Edinburgh,Scotland. Wilmut took an egg cell from a Scottish Blackface (SB) ewe and removed its genetic material. Next,a cell from the udder of a 6-year-old Finn Dorset ewe was cultured and injected into the enucleated egg cell. A spark of electricity then fused the udder cell with the egg cytoplasm and stimulated the egg to grow. Finally,the embryo was placed into the womb of a surrogate SB sheep. Dolly was born in 1996 | |
