Perspectives on Vatican Stem Cell Meeting: CIRM, Embryonic & Adult Stem Cells

April 27, 2016 / Professor Paul Knoepfler, Ph.D. / 3 Comments

What is a Vatican Stem Cell Meeting like? Over the years, the Vatican has expressed interest and even invested money in the adult stem cell field. Not surprisingly, they’ve also been critical of embryonic stem cell research. Interestingly their own stem cell meetings have at times stimulated heated debate for various reasons and one was even cancelled with […]

Key Remaining Questions about STAP Cell Mess

September 24, 2015 / Professor Paul Knoepfler, Ph.D. / 1 Comment

The publication yesterday of two papers refuting the existence of so-called STAP cells marches us closer as a field toward closure on this unfortunate situation. Close, but not quite there. We know a lot more about what went happened, but 5 key questions remain. There is a chance that we may never get answers to

New Nature papers debunk STAP cells

September 23, 2015 / Professor Paul Knoepfler, Ph.D. / 6 Comments

Today marks nearing the completion of a full circle for one of science’s biggest controversies: the STAP cell fiasco. Today STAP cells are completely refuted with the publication of two new papers in Nature and we know much more–with some notable gaps still–about what went wrong. STAP cells debunked In January of last year, an

Researchers in China make genetically modified human embryos

April 22, 2015 / Professor Paul Knoepfler, Ph.D. / 3 Comments

Rumors have been flying for months that researchers in China and possibly elsewhere were shopping papers around at high-profile journals that reported gene editing and genetic modification of human embryos. Update: apparently this paper (HT to @JohnBorghi) was only reviewed for 2 days (see image at bottom of post), raising major concerns about the depth of

Woman grows nose tumor in spine after stem cell injection

July 8, 2014 / Professor Paul Knoepfler, Ph.D. / 5 Comments

Clare Wilson over at the NewScientist has reported the case of a woman given an experimental stem cell treatment in Portugal for a spinal cord injury who later developed a strange tumor consisting of nose tissue. I highly recommend going over to that site and reading her excellent article. What’s the deal with this case? The woman was

What are VSELs and why are more clinics selling them?

July 24, 2013 / Professor Paul Knoepfler, Ph.D. / 6 Comments

One of the more controversial areas in the stem cell field has been over a stem cell type that only a handful of researchers have been able to find and study: very small embryonic-like stem cells or VSELs. These days some are calling them V-cells too. I’ve been getting an increasing number of questions from
