When I was first really getting into stem cells as a trainee the name Catherine Verfaillie came up as a scientist to watch in the adult stem cell area. It wasn’t too long after that though that I started hearing that some of the work from her lab at the University of Minnesota was being questioned.

Now 20+ years later, the story continues with a new retraction.

While there were once glowing stories about Catherine Verfaillie including one from University of Minnesota referring to magic stem cells.

Dubious or even fake stem cells come to mind after latest Catherine Verfaillie retraction

Here’s a piece on the new retraction. Nature retracts highly cited 2002 paper that claimed adult stem cells could become any type of cell, Retraction Watch. Not all retractions are of equal importance. We just got from Nature arguably one of the most important and long-overdue stem cell research paper retractions ever. It’s remarkable that the journal took this long to retract the paper. It seems more recent work by Elisabeth Bik and others played a role here.

The retracted paper claimed that multipotent adult progenitor cells (MAPCs) had unusual potency and could engraft. MCAPs were thought to be kind of like a cousin to MSCs. Catherine Verfaillie has had three other papers retracted as well.

According to Retraction Watch this is the most cited retracted paper in history with nearly 4,500 citations. This kind of flawed paper does immense harm to science. The delay in retracting it just makes things worse too.

This also brings to mind MUSE cells, VSELs, and even  STAP cells. In my view, none of these are real, naturally occurring stem cells. I still run into comments from people every few years who suggest that stress can make pluripotent stem cells from regular adult cells.
