Dissecting that Neanderthal brain organoids Science pub

neanderthal human brain organoids

Organoids and especially brain organoids, which are made from pluripotent stem cells, are one of the most interesting developmental biology technologies of the last half a dozen or so years. Still some folks can’t help but get carried away when thinking about brain organoids it seems. A new Science paper from a team led by …

Jellyfish on the brain: a critical look at Prevagen

crystal jellyfish aequorea victoria, Prevagen

I’ve been asked many times over the years if stem cell injections at for-profit clinics can help brain function, but recently the more common query is whether brain supplements such as Prevagen actually work. I’m skeptical of both unproven stem cell injections and supplements that are supposed to somehow help the brain, but some of …

Weekly reads: Alzheimer’s, dinosaur brains, teratoma, vampire amoeba, new H3K27me3 reader

vampire-amoeba-sm

Anyone with a seemingly only semi-functional nervous system now post-election might be turning to science to help their brains bounce back. Here are some of the things I’ve been reading or hope to soon. In good news for the stem cell and regenerative medicine field, especially here in California, it looks like us California voters …

Weekly reads: lab meat, crow brain biology, direct reprogramming, more

Stacho-et-al-Science-2020-Fig-1small

Does time seem somewhat warped to anyone else in 2020 even without having  had COVID, which could alter brain function? It just seems like with everything going on that time simultaneously both drags and zooms by this year. One sort of reassuring element is that papers keep on being published so we can enjoy cool …

Reciprocal CRISPR gene editing in pediatric glioma: defining mechanisms & testing drugs

reciprocal-CRISPR-mutant-H3.3

My lab’s new paper in Communications Biology focused on high-grade pediatric glioma that have mutant histone variant H3.3 and we did something fairly novel that we are calling reciprocal CRISPR. Kids with these tumors have a near zero survival rate within a few years of diagnosis so we as a field desperately need something new to give …

Probing F1 legend Michael Schumacher stem cell juice story

Michael-Schumacher-stem-cells

What’s the deal with Michael Schumacher and his Hail Mary stem cell procedure. Usually when we hear about celebrities getting unproven stem cells, it’s the celebrity themselves or their PR machine hyping it in exchange for something like free treatments or even money from those offering the stem cells for sale, but in the past …

Probing Nature pub’s puzzling claim of brain cells globetrotting into prostate tumors

Mauffrey-Nature-Prostate-Neural-invasion-2019-Fig-3ce

A new Nature paper makes the striking claim that neural precursor cells of the brain migrate all the way to prostate tumors. Furthermore, the team led by Claire Magnon claims that these long-distance cellular travelers from the brain not only take up residence in the prostate but also strongly drive progression of the prostate cancer …

Weekend reads: reversing death of pig brain cells, brain-gut stem cell link, plant stem cells, & more

pig-brain-fighting-death

It’s been a cool week for stem cell and other associated kinds of research. In this post I have a series of links to a variety of interesting developments and papers. Gene therapy cures bubble boy infants. William Wan over at the WaPo on this good news. Nope, this wasn’t done with CRISPR, but rather …
