CRISPR reagents injected into the amniotic fluid inactivated a gene in the fetuses that would normally cause lung disease and kill the mice a few hours after birth.
Researchers edited macaque embryos to induce symptoms of sleep disorders and chose one animal to clone. A bioethicist questions the study’s appropriateness.
Last year, researchers claimed the gene-editing method had accuracy issues, but a new whole-genome sequencing analysis by the same team finds otherwise.
Using CRISPR-Cpf1 gene editing, researchers have fixed mutations that cause a form of muscular dystrophy in cultured human cardiomyocytes and a mouse model.
