Earlier today, regulators from the United Kingdom’s Human Fertilisation and Embryology Authority (HFEA) approved an application by researchers at London’s Francis Crick Institute to use a new and powerful gene altering tool called CRISPR-Cas9 in human embryos for fertility research. It’s the first time a regulatory agency has approved genetic modification in human embryos.
According to the HFEA’s decision, researchers led by Kathy Niakan, a developmental biologist at the Crick Institute, will be allowed to genetically modify human embryos for a study on how they develop during the first few days after fertilization. Read more.
