"Stuart Newman: I'm here to argue that not only is full term cloning a bad idea, as Dr.Jaenisch forcefully pointed out, but that so-called therapeutic cloning, that is, nuclear transfer to make stem cells, is also in the long run going to be a bad idea. And I want to emphasize that my views on this don't arise from any notion of the sanctity of the embryo or any religious ideas or anything like that. But I do feel that there's probably nobody in this room that won't have some point in which they say, this is unacceptable. So for example, if a clonal fetus is allowed to develop to seven months, in order to harvest cells, this might be unacceptable to more people than growing clonal embryos for only seven days or 14 days. Probably everybody in this room would say, we certainly don't want to make full term babies for the purpose of transplanting tissue. Probably everybody would object to that. What I would like to convey to you is that the logic of the science and medicine is leading us in that direction. Not because anybody is motivated to do that per se; specifically, I don't think any of the scientists involved are motivated to do that, but there are all sorts of pressures, patient pressures, commercial pressures--and the patient pressures I believe are very genuine, authentic and must be satisfied in some way, so I'm not arguing that there shouldn't be patient pressures--but there will be pressures to bring us to the point. As was quoted from my Senate testimony, there are, in fact, stem cells that can be harvested from two month old embryos. These are called “embryo germ cells.” So if clonal embryos were produced, and it became possible, as some scientists are attempting, to grow the embryo for two months rather than just for seven days or 14 days, it would be possible to harvest these embryo germ cells. Now, why would you want to do that? John Gearhart at Johns Hopkins has worked on those cells, and has shown that they are apparently as versatile as embryo stem cells from the early petri dish cultures, but they don't have the same propensity to cause cancer when transplanted into adult animals. Now that's a very important motivation for harvesting these later stem cells."
