After Dolly, Mickey?

Rumours of a cloned mouse were rife at a biotechnology conference in New York
last month. And Ryuzo Yanagimachi of the University of Hawaii, whose work on
freeze-dried mouse sperm is also in the news
(see p 4), appeared to confirm last
week that he had cloned a rodent. According to reports from a meeting in
Falmouth, Massachusetts, he flashed up a slide of Dolly and announced that “she
is not alone”.
