First Human Embryos Edited in U.S.

TECHNOLOGYREVIEW – July 26, 2017:┬áResearchers have demonstrated they can efficiently improve the DNA of human embryos.

The first known attempt at creating genetically modified human embryos in the United States has been carried out by a team of researchers in Portland, Oregon, Technology Review has learned.

The effort, led by Shoukhrat Mitalipov of Oregon Health and Science University, involved changing the DNA of a large number of one-cell embryos with the gene-editing technique CRISPR, according to people familiar with the scientific results.

A video shows the injection of gene-editing chemicals into a human egg near the moment of fertilization. The technique is designed to correct a genetic disorder from the father.

Until now, American scientists have watched with a combination of awe, envy, and some alarm as scientists elsewhere were first to explore the controversial practice. To date, three previous reports of editing human embryos were all published by scientists in China. Link: Read Complete Article
