20 predictions for stem cells & regenerative medicine in 2018

stem-cell-crystal-ball-300x3001

Every year I look into my stem cell crystal ball and make predictions for our field including regenerative medicine. Well, I don’t really look into a crystal ball, but I try to use a combination of what I’m hearing through the grapevine, stuff I’m reading, some info that is not yet in the public domain, …

7 tech hurdles to human germline CRISPR

Human-crispr-challenges

Human germline CRISPR raises major bioethical considerations, but what about technical issues? Setting aside the many ethical issue about the general idea of human modification itself, could this really work? Yes in theory it could, but there are some very tough technological challenges that could and likely would cause failures or unacceptable outcomes at many steps …

Countering that Pro-Heritable Human CRISPR WSJ Piece

human-embryo-modification

It’s germline, heritable human CRISPR time, right? Wrong. But the particularly enthusiastic supporters of heritable human CRISPR often cite hypothetical benefits in glowing terms, but either don’t mention risks or strongly downplay them. These fans also tend to leave alternative, proven and safe technologies such as preimplantation genetic diagnosis (PGD) out of the discussion or …

1st Knockout Human Embryos Made with CRISPR: My Take on the Pub

Fogarty-Fig-3d-human-embryo-CRISPR-e1505774206656

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 …

Doubts raised on key points of Nature paper on CRISPR gene editing of human embryos

Egli-Mitalipov-preprint

Is it possible that CRISPR gene editing actually didn’t happen in many of the human embryos in that big Nature paper that made such news a couple weeks back? Some doubts have emerged that call the main conclusions of the paper into question and argue that more definitive studies are needed to be sure. An …
