The first successful editing of DNA in multiple human embryos has been conducted for the first time in the United States, scientists say.
Using gene-altering technology called CRISPR, the team at Oregon Health and Science University in Portland altered the DNA of multiple one-cell embryos, according to US News & World Report.
This is not the first time that DNA has been edited in human embryos, but the researchers solved previous issues with "off-target" editing by injecting CRISPR into the eggs at the same time they were fertilized with sperm.
The embryos were allowed to grow for only a few days, but the research could help advance efforts to eliminate or correct genes associated with inherited diseases, according to US News & World Report.
The research was published in MIT Technology Review.
While concerns have been raised about genome editing, a U.S. National Academy of Sciences and the National Academy of Medicine report released earlier this year says gene editing is "a realistic possibility that deserves serious consideration," according to US News & World Report.
