Pioneering Mouse Cloning Researcher Ryuzo Yanagimachi Passes Away at 95
Ryuzo Yanagimachi, a pioneering fertility researcher, has passed away at the age of 95. In 1998, he and his team at the University of Hawaii successfully cloned multiple generations of mice using a more elegant technique than the one used to clone Dolly the sheep. Yanagimachi's work demonstrated that cloning was not a fluke and achieved a higher success rate than previous methods. He remained skeptical of human cloning, emphasizing the dangers and moral implications. Yanagimachi's contributions to fertility research earned him recognition, including the Kyoto Prize, Japan's highest private honor.
