Cloned, fertilized embryos look alike
New report suggests faulty nuclear reprogramming not to blame for trouble with cloning
Nov 28, 2005
Researchers have shown that cloned embryos undergo complete nuclear reprogramming and resemble fertilized embryos. The report, appearing in the December 6 issue of
"It's a surprising result that reprogramming obviously works very nicely," Heiner Niemann at the Institute for Animal Breeding in Neustadt-Mariensee, Germany, told
Thirteen mammal species have been successfully cloned to date, but only 1-5% of cloned embryos ever produce live young, regardless of species. In the current study, Xiangzhong "Jerry" Yang, at the University of Connecticut, Storrs, Ct., along with...
