Big patent & IP implications or even ‘war’ from STAP stem cells?

February 3, 2014 / Professor Paul Knoepfler, Ph.D. / 3 Comments

A new article in the major Japanese newspaper, Asahi Shimbun, just came out suggest major intellectual property (IP) and patent issues related to stem cells including the new stress induced STAP stem cells. The piece is entitled provocatively enough “Global patent war looms with epoch-making discovery of STAP cells“. That’s strong language. The article begins […]

Poll: Do you believe in STAP stem cells?

January 30, 2014 / Professor Paul Knoepfler, Ph.D.

There’s a tremendous buzz about STAP cells (see more here and here). The buzz runs the gamut from true believers to complete non-believers and everything in between. What do you think? Take our poll below.

Weekly reads: abundant Abcam prices, speedy aging & cancer, stemmy CAR-T, more on STAP

April 14, 2024 / Professor Paul Knoepfler, Ph.D. / 3 Comments

When a vendor of important reagents like antibody supplier Abcam charges big money, those high Abcam prices could negatively impact research in the long run. Some of the prices are so high that buying just a few antibodies could take up a small but meaningful slice of an entire R01 grant. Sky-high Abcam prices I’ve

Weekly reads: late Macchiarini retractions, stem cells & Lululemon

October 29, 2023 / Professor Paul Knoepfler, Ph.D. / 8 Comments

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 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

Heart stem cells trial mostly disappoints but is oversold

March 2, 2023 / Professor Paul Knoepfler, Ph.D. / 6 Comments

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

Fact-checking VSEL stem cells & VSEL treatment

June 7, 2022 / Professor Paul Knoepfler, Ph.D. / 6 Comments

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

What are adult stem cells & their clinical applications?

June 16, 2021 / Professor Paul Knoepfler, Ph.D. / 2 Comments

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

STAP cell deja vu? 28 VSEL papers flagged by Bik

December 3, 2020 / Professor Paul Knoepfler, Ph.D. / 8 Comments

The stem cell field has puzzled on and off for years over a constellation of papers on purported stem cells including so-called VSEL and MUSE cells. Many of us haven’t been convinced that these are real stem cells. I see VSEL and MUSE fitting into a larger pattern of dubious stem cell claims including the STAP
