A scientist in Sweden has started trying to edit the DNA in healthy human embryos, NPR has learned.
The step by the developmental biologist Fredrik Lanner makes him the first researcher known to attempt to modify the genes of healthy human embryos. That has long been considered taboo because of safety and ethical concerns.
Lanner is attempting to edit genes in human embryos to learn more about how the genes regulate early embryonic development. He hopes the work could lead to new ways to treat infertility and prevent miscarriages. He also hopes to help scientists learn more about embryonic stem cells so they can someday use them to treat many diseases.
The fear is that Lanner's work could open the door to others attempting to use genetically modified embryos to make babies.
Making changes to the DNA in human embryos could accidentally introduce an error into the human gene pool, inadvertently creating a new disease that would be passed down for generations, critics say.

Almost every day I am reminded that we are in the midst of a fertility panic. Whether it’s the Vice President exhorting Americans to have more babies or The New York Times running yet another story about the fertility cliff, fear about falling fertility rates is everywhere. While centrally concerned with declining rates of childbearing, Anna Louie Sussman’s new book, Inconceivable: The Impossibility of Family in an Age of Uncertainty, is a welcome antidote to the panic.
