First, breeding animals that have or could develop human germ cells in their gonads should not be allowed.
To that end, Saitou's team recreated the developmental process of human germ cells, which gives rise to reproductive sperm and eggs.
He pointed out that the new capabilities to precisely edit the genome has sparked off an intense debate in the USA and elsewhere, since the new precision tools could also be applied to modifying the genome in human germ cells or embryos.
