Japan’s biggest daily newspaper, Yomiuri Shimbun, made international news when it reported a few days ago that iPS cells had been transplanted into human patients by Hisashi Moriguchi. In this morning’s paper, Yomiuri Shimbun issued a painful front page admission (happily reported by competing paper The Asahi Shimbun) of publishing false information about the alleged transplants, which […]

More and more evidence is accumulating that the alleged iPS cell transplantation in human patients by Dr. Hisashi Moriguchi was bunk. Nature today has a piece out today on the story providing more quotes about the case that suggest the whole thing was made up. Rather than re-hash all the details, in this post I’m going

Hisashi Moriguchi had a poster up at the NY Stem Cell Meeting yesterday and has done interviews with Japanese media saying that he has led a team that transplanted iPS cells into human patients. Reportedly his poster said and the newspaper articles have stated that the iPS cell transplant work had IRB approval from Harvard

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 seems like just yesterday I was blogging about how concerned I was that iPS cells might be used in early phase human clinical trials as early as next year and that would be high risk given safety concerns about iPS cells. Oh, it was yesterday. Now today….. Yomiuri Shimbun, one of the top newspapers

Are iPS cells being rushed to the clinic or has their time come?

/ / 2 Comments

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

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

The stem cell community is buzzing today with excitement about the Nobel Prizes deservedly awarded to Shinya Yamanaka and John Gurdon for their pioneering work on cellular reprogramming. However, it is also just as worked up about the strange omission in this award of what could have been a third scientist awarded the prize for
