Of course, there is still a long way to go before this particular method will be tested on humans (it was tested on mice), and an even longer way to go before it'll be used in medical therapies (if it ever will translate into therapies), but one thing is becoming clear: We need not compromise our moral principles and rush into government - funded embryo - destructive research.

Earlier versions of these «base editors,» which target typos related to the other half of disease - causing genetic spelling errors, have already been used to alter genes in plants, fish, mice and even human embryos.

Embryonic stem (ES) cells, harvested from three - and - a-half-day-old mouse embryos or five - and - a-half-day-old human embryos, are referred to as pluripotent because they can become any of the thousands of cell types in the body.

IN THE BEGINNING Early embryos (a four - cell embryo shown) from mice and humans look the same on the outside, but gene activity studies show some big differences under the hood.

The team spent over a year optimising their techniques using mouse embryos and human embryonic stem cells before starting work on human embryos.

Izpisua Belmonte and colleagues published work in the journal Nature last year reporting that they had been able to integrate human stem cells into early - stage mouse embryos so that the human stem cells began the first stages of differentiation — they appeared to begin the process of generating precursors of the body's various tissues and organs.

Both human embryonic stem cells (hESC) and induced pluripotent stem cells (iPSC) can colonize the mouse embryo in a manner predicted from classical developmental fate mapping and faithfully recapitulate tissue - specific fate post-transplantation.
