gene hints at serious hurdle to reproductive cloning

Gene that’s key to cloning success also hints at serious hurdles to reproductive cloning. Scientists at the University of Pennsylvania have found that the activity of a single gene is a powerful predictor of whether newly cloned mammalian embryos will survive and thrive, but the gene’s sporadic expression in cloned mouse embryos casts fresh doubt on prospects for reproductive human cloning.
