Dr-Piero-Anversa

It’s been mostly a downbeat week on the stem cell news front including a deep revisit by Reuters to the Piero Anversa case that has new revelations. It’s ugly stuff involving other folks too. We’ll start on the iPS cell front, where a trial participant had a teratoma. I’ve had a long-standing interest in the …

What is a teratoma tumor? Research & treatment

What is a teratoma? human stem cell teratoma knoepfler lab sm

Sometimes on The Niche or while teaching students as a professor here at UC Davis School of Medicine, I’ve been asked: What is a teratoma? Not all tumors are created equal and some like teratomas are particularly unusual. Exactly what is a teratoma tumor? Teratomas are germ cell tumors. What this means is that the …

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 …

The trouble with teratoma: a stem cell paradox

Teratoma

The trouble with the risk of teratoma presents a stem cell paradox. Stem cells possess two traits lacking in other cells: self-renewal and pluripotency. This duo of defining functions is key to the ability of stem cells to be used to treat patients via regenerative medicine. A paradox exists because while self-renewal and pluripotency are both …

Paper sparks renewed interest in transdifferentiation & clinical potential

transdifferentiation, iOPCS

There was a time when I thought transdifferentiation based approaches might quickly move into clinical trials. Then things kind of cooled off. We didn’t see many papers reporting methods to transdifferentiate cells. I still think that this technology, sometimes called direct reprogramming, has major potential. A new paper on making human brain cells this way got …

Fact-checking VSEL stem cells & supposed ‘VSEL treatment’

VSELs, vsel ratajczak paper issues

A few people in the stem cell field keep arguing that adult pluripotent stem cells exist, including so-called “very small embryonic-like stem cells” or VSEL stem cells. These days the supposed cells are called VSELs or V-cells too. Only a handful of researchers have ever been able to report finding and studying these cells. Others …

Review of Peter Diamandis Fountain Life clinics: more than stem cell hype?

Fountain Life Peter Diamandis featured

Many of you readers know tech guru Peter Diamandis for his great X PRIZE, but he’s also involved in the regenerative medicine world including a new effort called Fountain Life. Teaming up with life coach Tony Robbins and others for Fountain Life raises some red flags for me. What’s in this article Peter Diamandis and …

Regenerative reads: 3 CRISPR babies, FDA warning, diabetes, pubs

CRISPR-baby

If you celebrate the Thanksgiving holiday I hope you had a nice one and, right before it started a new article popped on the scene about the CRISPR babies. Before we discuss those three gene-edited people, who are now growing up into little kids, we hit a milestone on our YouTube Stem Cell Channel with …
