It’s an odd confluence of events this week that (A) the Nuffield Council, an ethics think tank, gives a thumbs up in a new report to heritable human genetic modification that would probably include using CRISPR in the same week that (B) a new paper reports that CRISPR can cause unpredictable genomic damage and several other concerning reports about possible CRISPR technology side effects or challenges have come out in the last few months. Talk about bad timing. They would probably counter my intro paragraph by saying …Read More

The human embryo CRISPR paper with Shoukhrat Mitalipov as senior author is coming soon. It will reportedly be focused on the use of CRISPR to genetically modify viable human embryos for reversal of a disease-associated mutation. While strangely press already broke early on this paper last week, as much as a week before the paper comes out, and that press suggests very positive data, how clear will that be from the paper itself? Here are some ideas on the big 5 questions (some include …Read More

More CRISPR’d human embryos, but this time in America? MIT Tech Review is reporting that Oregon scientist Shoukhrat Mitalipov has used CRISPR on human embryos in his lab in the US. Apparently a paper is in the works on this. While details are sketchy and some specifics remain to be clarified to be sure of what’s the deal here, this Tech Review report appears generally accurate based on what I’ve heard so this appears to be the first reported use of CRISPR on human …Read More

The first report of the use of CRISPR gene editing in normal human embryos was published today as a short paper from a team in China. There have been rumors for over a year that more CRISPR human embryo papers were coming including some using normal embryos. Here’s one and we can now expect more even as there remain scientific and ethical discussions about this kind of work. You can read the actual paper Tang, et al. here, published in the journal Molecular Genetics & Genomics. …Read More
