There’s a new paper in Cell Stem Cell on esophageal organoids that has really caught people’s attention. It is entitled, “3D Modeling of Esophageal Development using Human PSC-Derived Basal Progenitors Reveals a Critical Role for Notch Signaling.” It comes from a team led by Jianwen Que. Update: I didn’t realize when I first did this post that […]

What happens when one of the most exciting stem cell biotechs ViaCyte teams up with a firm like CRISPR Therapeutics to use a combination of gene editing and cell therapy? Hopefully a synergistic partnership emerges that in this case can develop an effective stem cell-based therapy for diabetes. You can see a press release on

What the devil is a vampire facial? I first heard about the vampire facial, sometimes also called a “vampire facelift” when professional celebrity Kim Kardashian reportedly got one. I weighed in on that five years ago here. There was some question in how this procedure was portrayed as to whether it involved stem cells, which

Time to sell exosome therapies to patients? No. Some stem cell clinics and related firms are looking for new ways to make profits and toward that goal a few have latched onto the legitimate buzz around exosome research. What are exosomes? Imagine if you could bubble up a pea-sized sphere off your skin full of
As exosome work advances, clinics pitch unproven therapies to patients Read More »
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

If it seems to you like dramatic cautionary tales about CRISPR accompanied by all sorts of media are coming at us more frequently, it’s not your imagination. In the latest yesterday, it was reported in a new paper led by Allan Bradley that CRISPR-Cas9 results in sometimes large-scale chromosomal lesions at or even away from the

One of the reasons I’m a scientist is that I find biology fascinating and admittedly novel biomedical science can really catch my eye, but more recently as a somewhat grizzled researcher, I’ve become increasingly skeptical about some “sexy” research and media coverage of it. A small red flag went up for me as I was

“If I’m going to the trouble of cloning myself, I want the clone to be a copy of me!” I’m imagining what someone might say if they were told that their expensive and ethically dubious personal cloning efforts produced a clone that was somebody else instead of them. Even if the clone was very similar
Surprising reason why human cloning may produce someone else Read More »
One of the highlights of Day 1 of #ISSCR2018 for me so far was the talk by Lorenz Studer (Co-Founder of BlueRock) on the use of human embryonic stem cell (HESC)-derived dopamine neurons for Parkinson’s Disease. Note that for this post and if I have time any others on this meeting, they are probably going

Could potential associated cancer risks claw into CRISPR’s potential? The short answer from both previous and new data is that while CRISPR gene editing impacts the P53 pathway, which is involved in cancer along with having many other functions, this news is neither too surprising nor a fatal flaw, but some caution is warranted. CRISPR
