Teruhiko Wakayama

Teruhiko Wakayama is a Japanese researcher at the University of Yamanashi's Advanced Biotechnology Center, known for his work in cloning. He is currently newsworthy due to the publication of a 20-year study on serial mouse cloning. This research, led by Wakayama, explored the limits of mammalian cloning by creating 1,200 mice over 58 generations. The study revealed that after approximately 25 generations, cloned mice begin to exhibit mutations, and cloning becomes incompatible with life after 57 generations. This finding demonstrates that cloning is not an infinite process and highlights the importance of sexual reproduction for long-term viability. Wakayama's research is significant because it provides crucial insights into the limitations of cloning technology and the biological constraints on replicating mammalian life indefinitely.
