For stem cell research, this was a “Who’s Who?” gathering. Those taking the stage at United Nations headquarters in New York included Whitehead Founding Member Rudolf Jaenisch; Douglas Melton of Harvard University; Roslin Institute’s Ian Wilmut, the Scottish embryologist who cloned Dolly; and Seoul National University’s Shin Yong Moon, who culled embryonic stem cells from the cloned human blastocyst earlier this year.
