On the order of two to three dozen women would have to volunteer, if statistics from the experience from sheep are any guide. It could require a lot more. Some eccentric millionaire might be able to afford it. Desperate economic conditions might force a sufficiently large number of women to offer their services. First of all, notoriety, book and movie contracts, endless fodder for the National Enquirer s of this world, interviews with Ted Koppel, Barbara Walters, Oprah, etc.
Science tends to be driven by simple curiosity, and by the desire of some scientist to do it first.
We live in the age of celebrities. With a net increase of approximately 100 million people on this earth every year, a few such clones would hardly make a difference, but their celebrity status would be assured for a short while. I doubt it. We learned decades ago that one can immunize children against measles, and yet a dozen children die every year in Los Angeles because mothers cannot afford immunizations. The problem is the economy, not the science.
