Fact-checking VSEL stem cells & 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

stem cells differentiating into neurons and glia

It’s been quite a ride doing this blog on stem cells and other technologies for more than a dozen years. So far it seems like I’ll keep it going. A large part of the reason is because of people needing good information about our field. Those people include scientists and physicians but also many in

Wild History of VSELs Predicts Future of STAP Cells?

VSEL-cover-image

Very small embryonic-like stem cells aka VSELs are reported to be tiny adult stem cells that are pluripotent or non-existent depending on whom you talk to most recently or which paper you just read. These very controversial cells (which I once compared to the Sasquatch) have a wildly fluctuating history with their existence on multiple occasions

Interview with NeoStem CEO Robin Smith Part 2: VSEL, ES cells, and iPS cells

I recently did a Q&A interview with NeoStem CEO Dr. Robin Smith. I posted Part 1 of that interview a few days ago here. Now we have part two focused on VSEL, ES cells, and iPS cells. PK: I frequently have readers of my blog ask questions about VSEL. They seem puzzled and unsure of

Do human Very Small Embryonic-Like Stem Cells (VSEL) exist as a normal population of actual stem cells?

Supposedly there is a type of normal adult stem cell that intrinsically possesses many of the same properties as embryonic stem cells (ESCs). No reprogramming needed. No blastocysts needed. These reportedly amazing cells, called Very Small Embryonic-Like Stem Cells (VSELs), can in theory be isolated from umbilical cord blood (UCB) or even bone marrow. Yet

Catherine Verfaillie retraction, Catherine Verfaillie

When I was first really getting into stem cells as a trainee the name Catherine Verfaillie came up as a scientist to watch in the adult stem cell area. It wasn’t too long after that though that I started hearing that some of the work from her lab at the University of Minnesota was being

Key Mayo Clinic stem cell webpage is overexuberant & outdated

The Mayo Clinic.

The Mayo Clinic does some great research on stem cells and regenerative medicine. However, at times I’ve felt that a few Mayo researchers are overexuberant. This mainly relates to certain not-yet-proven stem cell and related offerings. Fitting with that perception, the Mayo website also has some inaccurate stem cell content that leans toward overstating things.
