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 …
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 …
Now and then we will revisit some of our most popular posts and/or posts with the most comments. One of the best: The Monster Tumor: What is a teratoma really? You can go to the link above to read the original post and comments but I’ve pasted the post itself below. In stem cell research …
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 …
I wrote a few weeks ago about a firm called RGCC or Research Genetic Cancer Center, which sells what I see as an unproven RNA therapy to clinics throughout the US. The approach is called supportive oligonucleotide therapy or SOT. After buying it from RGCC, the clinics then sell SOT injections for Lyme disease, other …

Epigenetic reprogramming is a term used in cell biology that is increasingly ending up in news stories too. Unfortunately, some folks, especially in the cellular rejuvenation and anti-aging space, are getting this term and other things confused. Just to start off, epigenetic reprogramming does not specifically mean cellular rejuvenation. The goal of today’s post is …

A days ago the news came about Mesoblast not getting FDA approval for its MSC product for GvHD. The MSC area has had a rough few years with various clinical trials including for COVID. The “stem cells for heart disease” arena has also had a tough time. Here’s more news along these lines: BioCardia pauses enrollment in PhIII trial …

Who is David Sinclair and why is he all over the media related to anti-aging efforts? This post is my effort to fact-check Sinclair’s statements in the context of the broader rejuvenation arena. In the process I also review his most recent paper from my view as a stem cell and cancer biologist interested in …

As we think about how much of a role belief should play in the hard sciences such as cell biology, a supposed cell type called VSEL or very-small embryonic stem cell-like cells comes to mind. For these guys it seems to me that the ratio of data to belief isn’t great. VSELs have nine lives. I …
