Reproductive Cloning in Sight?

A story in Wired looks at the possibility of human cloning. In a study led by Robert Lanza, scientific director of Advanced Cell Technologies, he showed that the genes turned on in normal human embryos are the same genes turned on in human clones. When they performed SCNT using egg cells from both humans and animals, "the animal-human hybrids didn't develop normally, but the human-human cloned embryos displayed many of the genetic characteristics of healthy development," writes Brendon Keim. While it opens the window further for successful human reproductive cloning, New York Medical College cell biologist Stuart Newman is not sold. Though the paper "shows that interspecies SCNT is a bust," Newman says, there are still "substantial differences" between human clones and IVF embryos.
