Scientists Edit Gene For Blood Sickness In Human Embryos

“Although we did not achieve 100% repair in human embryos, we and other groups have reported 100% base editing in mouse embryos.
“The scientists noted that the base editing wasn’t uniform across all cells in the embryos, resulting in mosaic embryos.
“So they already established that base editing can function efficiently in human embryos derived from fertilized eggs.
“How it worksThe new study involved base editing experiments in cells from beta-thalassemia patients and human embryos.
“Our data highlight the tremendous potential of correcting homozygous disease and compound heterozygous mutations by base editing in human somatic cells and embryos,” the scientists wrote.
