Did Dr. Hisashi Moriguchi really transplant iPS cells into human patients? The story has the stem cell field abuzz. My mind keeps changing on this one as earlier today I thought the whole thing maybe was a bunch of fluff, but now there is yet another new article (see headline below) in the Daily Yomiuri providing […]
It has been a big week in very different ways for the stem cell field related to induced pluripotent stem (iPS) cells. First, we had the Nobel Prize deservedly going to stem cell hero, Shinya Yamanaka. Great news! Congratulations to Dr. Yamanaka. Unfortunately, now, we have a puzzling story that iPS cells have been reported
Multiple independent sources have told me that Moriguchi’s poster at the New York Stem Cell Foundation (NYSCF) meeting, reporting iPS cell transplants into human patients, has been taken down. More to come…..

The story in a major Japanese newspaper that iPS cells were transplanted into human patients has struck like lightning in the stem cell field. While the facts surrounding this case are only now being revealed, my current opinion based on directly or indirectly getting feedback from experts is that the transplant work most likely never
Opinion: iPS transplant work likely never occurred Read More »
The strange, doubt-filled story that iPS cells have already been transplanted into human patients is generating a great deal of interest today even as Harvard officially indicates it never approved any such work. According to the original Japanese newspaper report, Dr. Hisashi Moriguchi transplanted iPS cell-derived heart cells into patients, work approved by Harvard. The
The following comment was posted on my blog post about the emerging, yet still confusing story reported by the major Japanese newspaper, raises doubts about the accuracy of the newspaper article. Harvard University, the Harvard Stem Cell Institute, Harvard Medical School, and Massachusetts Hospital have issued the following joint statement: “Hisashi Moriguchi was a visiting
The iPS cell field has run fast and furious over the past 6 years reaching a big milestone surprisingly quickly on Monday with Shinya Yamanaka winning the Nobel Prize. But is the field going too fast? In August I argued that iPS cells are not quite ready for primetime (i.e. clinical trial studies). Now in
Are iPS cells being rushed to the clinic or has their time come? Read More »
The great news of Yamanaka and Gurdon getting the Nobel Prize for cellular reprogramming is still resonating in the stem cell field. My heartfelt congratulations to two amazing biologists! Also still ringing in my ears from so many people contacting me about what is becoming a somewhat infamous “empty” third slot that the Nobel Committee
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

As I was compiling a list of the upcoming stem cell meetings the other day I got to thinking about the different kinds of stem cell meetings and how diverse they are. Some didactic in a stodgy kind of way, while others are just as educational and instructive, but in a more enjoyable format. Some
