An editorial posted online on 28 April says the journal's objective in publishing the study was «the sounding of an alarm to draw immediate attention to the urgent need to rein in applications of gene - editing technologies, especially
in the human germ cells or embryos.»
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.

The
germ cells made from stem cells stopped differentiating
in the mice before they produced mature sperm (likely because of the significant differences between the reproductive processes of
