This is the breakthrough that holds promise. Editing -- wrong. Looking backwards, it was just a day or so later that the reprogramming news came out, even though Wilmut endorses it along with his announcement not to pursue human cloning. The jumble of important points was further jumbled by my reporting. The new of monkey cloning was just that - primates have been successfully cloned and very many eggs were used. The inefficiency of this process made direct programming a more attractive endeavor. Of course, days later, it would become even more attractive, with the news of Thomson and Yamanaka's success.

Conventionally, researchers have used a dye called Hoechst and ultraviolet light to locate and remove an egg's DNA. But Mitalipov's group found that both the light and the dye damaged the egg.
