Tweezers, a coin and a glass pipette – thanks to John Gurdon’s inventiveness, these became crucial instruments in his stem cell research. With these tools and sensitive fingers, he managed to replace the cell nucleus in a fertilised frog egg with a cell nucleus from a mature tadpole – the first creation of a genetic copy, a clone, of a higher organism.
John Gurdon donated the pipettes to the Nobel Prize Museum in 2012.
