Scientist make knockout human embryos with CRISPR? Today we see a new Nature paper (Fogarty, et al.) on CRISPR “gene editing” of human embryos, this time from the UK from Kathy Niakan’s group. Niakan got UK permission about 18 months ago to CRISPR healthy human embryos so they’ve been hard at work since. Because Fredrik Lanner of Sweden (see my interview here) also has governmental permission to CRISPR healthy human embryos, I’m guessing we’ll see a paper from his lab soon too. If I …Read More

What really happened at the DNA level in the experiments in that high-profile CRISPR of human embryos paper from a team led by Shoukhrat Mitalipov at OHSU? Is the team right that they successfully conducted CRISPR of human embryos to correct a mutant gene, as they reported in their Ma, et al. Nature paper? Or is the Egli, et al. preprint that came out later in response to the Ma paper more likely to be correct in their implied argument that something else very probably happened instead? We …Read More
