Dr. Leon Kass, former chairman of the President's Council on Bioethics, said, "I do not think that this is the sought-for, morally unproblematic and practically useful approach we need."
Dr. Kass said the long-term risk of preimplantation genetic diagnosis was unknown and that the present technique was inefficient, requiring blastomeres from many embryos to generate each new cell line. It would be better to derive human stem cell lines from the body's mature cells, he said, a method researchers are still working on.
Wesley J. Smith is also unimpressed. What about Peter L.?
Update: Wesley J. Smith reads the article in Nature, not just the press release, and discovers, first of all, that the embryos from which the cells (yes, plural) were extracted were all in fact destroyed. So m-a-y-b-e at some time in the future (but not yet) we might be able to do what the articles suggested. A case of press boosterism, in other words. Smith also reminds us that the company (ACT) has profited from press boosterism in the past. Public opinion is trending in the direction of increasing support or stem cell research because of credulity among reporters, who rarely probe beyond the surface when claims of scientific advances of this sort are made.
