The Moriguchi iPS transplant fable: key lessons & where do we go from here

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 …

My thoughts on the Moriguchi iPS cell controversy

Moriguchi

My phone has been ringing and my email flowing at an even faster rate than usual over this still breaking story of the reported transplant of iPS cells into human patients by a Japanese scientist, Hisashi Moriguchi , who at some point was a visiting scientist at Harvard, apparently no more recently than 12 years ago. …

Moriguchi also claimed Harvard IRB approval for human studies in multiple 2012 published papers

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 …

Major Japanese newspaper reports iPS cells already transplanted into human patients at Harvard

iPS-cell-headline-clip1

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?

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 …

Wilmut voted most-deserving of 3rd Nobel slot with Yamanka & Gurdon in poll

Poll-results-Nobel

I have a poll running regarding who would have been the best choice to share the Nobel Prize with Shinya Yamanaka and John Gurdon, and so far the winner is Ian Wilmut, who cloned the first mammal, Dolly the sheep. I should have included another option to indicate the possible preference that NO ONE should …

Poll: who should have shared in stem cell Nobel Prize in third slot?

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 …

The dangers of direct to media reporting of unpublished, non-peer reviewed science: the Higgstery case

I was critical earlier this week in a post of what I perceived to be the over-the-top reaction to the whole Higgs Boson situation and press fest. I went so far as to call it “hysteria” or one could say “Higgstery“. In turn, I was criticized for that blog post for being too critical and spoiling people’s …
