When a team of Chinese scientists announced last spring that they had edited the genes of human embryos using the powerful new gene editing technology known as CRISPR / Cas9, the world suddenly discovered that the dystopian possibility of «designer babies» was no longer an unrealistic fantasy, but rather a technically achievable possibility that must be reckoned with.

Kathy Niakan and colleagues are providing new understanding of the genes responsible for a crucial change when groups of cells in the very early embryo first become organised and set on different paths of development.

The team has shown that new genes can be injected into the blood stream of a developing embryo.

Debate about so - called germline editing of eggs, sperm and embryos has been going on for decades, but it has come to a head in recent years with the development of a powerful new gene - editing technology called Crispr - Cas9 that can make extremely precise edits to DNA and which was used by the Chinese team and would be used by the British team.

But in recent decades, scientific advances — such as the ability to manipulate genes and turn them on and off in developing embryos — have provided us with a plethora of new information, and insights into how organisms develop and change.

The result was the discovery of three new mammalian genes - known as sonic, Indian, and desert hedgehog - and the realization that the proteins they coded accounted for a significant proportion of all developmental interactions known to occur in the vertebrate embryo.

The finding is a landmark in the new field of evolutionary developmental biology, or «evo - devo,» as its proponents call it, in which scientists study the patterns of gene expression in embryos to peer backward in time.

Beyond just screening embryos, germline therapy actually adds new genes to the cells.

In a mutagenesis screen for new maternal genes (Luschnig et al. 2004) we found that embryos from 2R -225-5 homozygous mutant germline clones lacked cuticle structures derived from the anterior and posterior poles of the embryo (Figure 1, A and B), resembling the phenotype of terminal - class mutations.
