john gurdon and shinya yamanaka. john pioneered the practice of cloning through his experiments on frogs. he is now a professor at cambridge. dr. yamanaka made international head lines in 2007 when he converted an adult skin cell into a stem cell without the use of an embryo. he's at the university of japan. i'm pleased to have both them both here at this table as they receive the lasker prize in new york. welcome. what's interesting about this your pioneer work was 30 years ago. >> yes. >> charlie: then you had a fuller implication. >> that's right. >> charlie: what did you do. >> i was involved in the early nuclear transif you are experiments as we called them. >> charlie: the new chest of the cell. >> yes you take the new chest of one cell and implant it into an egg having removed the chromosomes from that egg. so the egg has no genetic material of its own but it receives the nucleus from a specialized cell. any other kind of cell. and the outcome is that this combination can develop normally. these experiments su
