Good final grades on my 20 x 2018 stem cell predictions

stem-cell-crystal-ball-300x3001

Each year I make a list of stem cell predictions for the following year and I’ll release my predictions for 2019 soon, but first I’m grading how my 20 predictions for 2018 turned out. It seems I did better than usual predicting what would happen this year. I only got a couple partial credit or …

Mitalipov rebuts CRISPR pub critiques: strengthens case, but puzzles remain

Ma-et-al.-2018-Nature-FIgure-1

Remember that Shoukhrat Mitalipov lab paper on the use of CRISPR in human embryos? It’s back in the news. One of the biggest stories of 2017 centered on a Nature paper (Ma, et al., see my quick, initial review shortly after it was published here) from Mitalipov’s lab claiming both efficient repair of a disease-causing …

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, …

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 …

Mulling over that Mitalipov human embryo CRISPR pub, still many questions

human-embryo-modification

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, …

Mitalipov briefly responds to Egli preprint, stands by human embryo CRISPR pub findings

Shoukhrat-Mitalipov

There has been a wave of intense discussions both in the public domain such as on Twitter and behind the scenes over the new Egli, et al. preprint that challenges the main conclusions of the Ma, et al. Nature paper from Shoukhrat Mitalipov’s lab. Ma, et al. reported CRISPR gene editing of human embryos, arguing for …

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 …

Review of Mitalipov paper CRISPR’ing human embryos: transformative work on the edge

Human-embryo-CRISPR

In the same way perhaps that some excited relatives or parents-to-be both gush and worry about a baby before it is even born, our field has been transfixed for a week by the Mitalipov paper on CRISPR’ing human embryos even though the paper just now came out. Now that the paper is out, we can …

Big 5 questions anticipating Mitalipov human embryo CRISPR paper

human-embryo-modification

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 …

4 areas of debate on 1st human embryo genetic modification paper

human-genetic-modification

Last week was a big one for the life sciences in that we saw the milestone of the first ever published paper reporting human embryo genetic modification (see here and here). It was one of those situations where we knew it was coming, but it was still a jolt. Not surprisingly this event sparked intense discussion …
