Perspectives 10 years after STAP cells: the culture of science, misconduct, & hopes for progress

Haruko-Obokata-小保方-晴子-

Exactly ten years ago today, on January 29, 2014, I wrote about two new Nature papers on so-called STAP cells. The papers claimed that stress alone could convert regular non-stem cells into some of the most powerful stem cells. More specifically, the authors claimed to make pluripotent stem cells similar to iPS cells this way. […]

Paolo-Macchiarini

Paolo Macchiarini is one of a small group of people in the stem cell universe whose misconduct has blown up in the press. Piero Anversa, Haruko Obokata, Hwang Woo-Suk, and some operators in the unproven stem cell clinic sphere come to mind. Macchiarini published quite a few seriously problematic papers, some of which just hung

Retraction watch

Retraction Watch has been a great resource for those of us who have been following research misconduct. They widely cover and conduct research on retractions, corrections, and other developments in this space. Unfortunately, there’s been plenty to write about even just within the stem cell and cell therapy arena, which is my primary interest. Think

stem cell for hair loss

There seems to be a never-ending supply of stem cell for hair loss research but a new article invokes a novel mechanism. Stem cell for hair loss research and cell mechanics Here’s a recent news item about a PNAS paper: Coaxing hair growth in aging hair follicle stem cells, NW Now. A common theme is things

Heart stem cells trial mostly disappoints but is oversold

heart stem cells

Are there endogenous adult heart stem cells that are useful in cardiac disease or can stem cell infusions help ailing hearts? As to the first question, the adult heart does not appear to have meaningful numbers of true stem cells. Further, testing the idea of infusions of stem cells for heart disease has so far been giving

Paolo Macchiarini guilty in criminal stem cell case but does a Houdini again

Paolo-Macchiarini

Dr. Paolo Macchiarini exemplifies how things can change quickly in the stem cell world and go from sky highs to deep lows. Stem cell rollercoasters Over the years, a few academic stem cell researchers as well as some operators in the unproven clinic sphere have had dizzying ups and downs. There’s John Kosolcharoen. His company

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

Elizabeth Holmes, Theranos, & lessons for the stem cell field

Elizabeth Holmes, Theranos

When I read about Elizabeth Holmes and her blood testing startup Theranos I see parallels to hucksters in the arena of stem cells and cell therapy. I’m thinking especially of the unproven stem cell clinics out there. It goes farther than that though too, including people who aren’t hucksters at all but get caught up

What are adult stem cells & their clinical applications?

mesenchymal cells

When someone uses the term “adult stem cells” you might think that simply means stem cells from adults. However, it’s not that simple. The goal of today’s post is to help you get all the key facts about adult stem cells. This includes the different types of adult stem cells and their clinical potential. What
