Goodbye, Dolly?

SciAm has an article and excerpts of an interview with Ian Wilmut, the first person to use somatic cell nuclear transfer to clone a mammal. Wilmut has almost entirely switched his research focus to creating iPS cells because, like many others, he sees that weeding through the ethical and technical issues around SCNT just isn't worth it. He's still working on figuring out the mechanism behind the creation of iPS cells, though, and thinks that SCNT still holds a place in research. But, "if iPS pans out, Wilmut predicts, nuclear transfer to produce cell lines may one day become a history lesson," says the article.
