The fast-moving stem cell field has enjoyed remarkable progress in the past 10 years despite some issues such as instances of stem cell paper retraction. This “modern” stem cell era that includes induced pluripotent stem cells (IPSC) has been striking for progress despite some challenges such as issues with publications. As a maturing field it is important to view our future through the realistic lens of our past and present, which means discussing both the good and the unpleasant issues. We also have to keep things …Read More

For the past few years post-publication peer review (PPPR) has grown in influence and one particular website, PubPeer, has become the primary go-to place specifically for blunt PPPR. The kind that happens in journal clubs in labs across the world. Comments on PubPeer have led to numerous serious corrections and retractions of flawed articles. I’m most familiar with its role in the STAP cell case. Both the founders of and most of the commenters on PubPeer have remained anonymous. That is until today. The founders …Read More

Each year towards the end of December I make predictions for the coming year as I did for 2015. In the past I usually make a top 10 prediction list, but for this year I made 20 predictions. Admittedly some of them may have been more hopes than predictions. At mid-year today on June 30th, how am I doing? See below. Note that of course for some the jury is still out. BTW, stay tuned for more on an upcoming update on the Japan …Read More

Researchers probing how to reprogram cells into powerful stem cells (induced pluripotent stem cells or IPSCs) and what the molecular mechanisms are behind this process have become entangled in a conflict. Of course over the years scientists including stem cell scientists have had their share of disagreements and debates in the past including heated ones, but this reprogramming clash has taken it up a notch beyond past ones and has some unique elements to it. For example, this scientific clash is unfolding largely in the public domain …Read More

A heated series of discussions on stem cell publications is ongoing on the Post-publication review (post-pub) website, PubPeer, which has been called by a PubPeer user “The stem cell shoot out“. This “shoot out” goes well beyond the one page on PubPeer. It is notable to see that the authors of the papers that are the focus of these interactions, often prominent stem cell scientists, are now sometimes participating in the discussions by leaving comments themselves on PubPeer. For instance, Austin smith has commented on PubPeer regarding ground …Read More
