I’ve been doing a poll on the extent to which people believe or do not believe in the stress-induced STAP stem cells reported in Nature last week. In just a few days of poll, we’ve got almost 400 respondents, which is great. It’s still not a scientific poll, but the results (above) are interesting for […]

The recent publication of two Nature papers by a team in part led by Dr. Charles Vacanti on acid treatment produced stem cells (so-called STAP stem cells) has been a blockbuster story in the stem cell field and has grabbed major global media attention as well. For background my review of the paper here and more thoughts here. Many

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.

The STAP papers on making iPS like cells using acid treatment of differentiated cells really has people talking. See embryo at right made from GFP reporter STAP cells that glow green. As I said in my review of the papers yesterday, there are still some critical things we do not know about STAP cells and I

In two Nature papers (here and here) published today researchers report the astounding finding of reprogramming differentiated cells back to a pluripotent or even totipotent state simply by exposing the cells to extreme environmental stress, creating cells they called STAP cells. Update: see more thoughts on STAP stem cells here. STAP cells: stressing the cell

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

In today’s post, I reviewed a stem cell clinic firm called Docere Clinics. In my opinion, there are some concerning issues here and reasons for caution. One type of procedure at Docere is particularly surprising and raises risks in my view. What is Docere Clinics? | What kind of stem cells does Docere use? | What they

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
