Imagine writing or editing an article for the WaPo about risky, unproven medical interventions for COVID that desperate patients might consider. Then you link directly to the websites selling this stuff in your article. What the heck? WaPo links to risky long COVID “treatments” By linking, you not only are driving customers to these firms, …

induced pluripotent stem cells clinical trials map

Induced pluripotent stem cells or iPS cells just might be the most exciting development in the stem cell field over the last 15 years. They have unique potential for clinical impact for regenerative medicine too. This may manifest both through their use to produce differentiated cellular therapies and indirectly via disease modeling as well as …

Mutations in pluripotent stem cells: No, the sky is not falling

May 2, 2017 February 1, 2021 / By Professor Paul Knoepfler, Ph.D. / 12 Comments

By Jeanne Loring “Mutation” and “cancer” are eye-catching words for a headline; add “stem cells” and there is a good chance that a lot of people will hear about it. These words have been liberally used in the press to describe the results of a recent publication: “Human pluripotent stem cells recurrently acquire and expand …

Is REGROW Act anti-embryo research? Pluripotent stem cells excluded

May 4, 2016 February 1, 2021 / By Professor Paul Knoepfler, Ph.D. / 10 Comments

The REGROW Act has attracted both support and criticism, including on this blog, for the changes it would mandate in the way the FDA regulates stem cell products. More specifically it would greatly reduce regulation of experimental stem cell products. I believe that would be dangerous to patients and to the stem cell field more …

If I only had a brain: brain organoids from pluripotent stem cells

August 28, 2013 February 1, 2021 / By Professor Paul Knoepfler, Ph.D. / 3 Comments

In a first for the field, scientists have used human pluripotent stem cells to grow miniature brain-like structures (brain organoids) in a dish in a lab (see beautiful image of one of these “mini-brains” at left from the paper). This exciting, pioneering feat, accomplished by a team from the Austrian Academy of Science in Vienna …

Jury is still out on purported adult pluripotent stem cells despite new MUSE paper

June 6, 2013 February 1, 2021 / By Professor Paul Knoepfler, Ph.D. / 14 Comments

Are MUSE cells for real? Stem cells come in different types that vary in a key property called “potency”, but very few are pluripotent. The more potency, the greater the flexibility of a stem cell to make other cell types. Flexibility in the cellular world is power. The most powerful stem cells generally used are …

iPS cells top poll as most clinically promising pluripotent stem cells

May 14, 2013 February 1, 2021 / By Professor Paul Knoepfler, Ph.D. / 3 Comments

I just closed my blog’s poll on what are the most clinically promising pluripotent stem cells. Why close the poll now less than 12 hours after I opened it instead of leaving the poll open longer? You’ll find out soon enough. I can’t resist teasing you readers sometimes. iPS cells were the big winners in …

Why Yamanaka deserved the Nobel Prize for induced pluripotent stem cells

October 8, 2012 February 1, 2021 / By Professor Paul Knoepfler, Ph.D.

I believe and have argued for years that Shinya Yamanaka, the discoverer of induced pluripotent stem cells (aka iPS cells) deserves the Nobel Prize. I’m very glad today that he received it. Some readers may find it a bit ironic that I believe so strongly in this way since over the years I have often …
