Alzheimer's, lipid droplets Alzheimer's

So many things go wrong during the lead up to clinically-evident Alzheimer’s disease. This complex disease pathway has, in turn, led to a vast array of approaches to try to treat or prevent Alzheimer’s. Most of these efforts one way or another have something to do with the amyloid plaques and tangles that accumulate in the […]

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.

Weekly stem cell reads: cancer paper mess at DFCI, H3.3, knees, surfer keeps on posting

Sholto David, stem cell, cancer retractions

It’s another one of those ‘double-grant’ weekends of grant writing (on brain cancer) and reviewing, but I’m still trying to find a bit of time for some other reading. There was some important news this week including a big mess of problematic papers at Dana Farber Cancer Institute (DFCI). Recommended reads Here’s the new WaPo

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

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

2nd chances after big misconduct? He Jiankui, James Wilson, others

James Wilson, Gene therapy

There have been rare instances like with scientist James Wilson where researchers were involved in what I would call major misconduct but somehow managed to bounce back. In a sense, they were given second chances in part by regulators but also by other scientists or supporters. However, after extraordinary misconduct, especially contributing to the death

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

4th Obokata retraction after Harvard investigation: STAP saga finally over?

si-Haruko

Retraction Watch broke the news that Haruko Obokata of the STAP cell train wreck now has a 4th paper retraction. The publication related to the controversial idea that adult tissues have pluripotent potential or actual pluripotent stem cells in them so it was kind of foundational for the debunked STAP cell idea. It also reminds

I’m enjoying attending and speaking at the annual Science Writers 2018 meeting in D.C. where I spoke this morning on a panel about stem cells. The session was specifically on the Wild West of stem cells. You can follow the meeting events on Twitter with the #sciwri18 hashtag. I had three wonderful fellow panelists, Marilynn Marchione of
