Exactly ten years ago today, on January 29, 2014, I wrote about two new Nature papers on so-called STAP cells. The papers claimed that stress alone could convert regular non-stem cells into some of the most powerful stem cells. More specifically, the authors claimed to make pluripotent stem cells similar to iPS cells this way. […]
The stem cell field has puzzled on and off for years over a constellation of papers on purported stem cells including so-called VSEL and MUSE cells. Many of us haven’t been convinced that these are real stem cells. I see VSEL and MUSE fitting into a larger pattern of dubious stem cell claims including the STAP

Once upon a time this blog and major outlets around the world were regularly writing about a Japanese stem cell researcher named Haruko Obokata (小保方 晴子). Whatever happened to Obokata and the other folks directly involved in STAP cell research? First, a bit of background because maybe still a few people never heard of STAP cells

Remember when the Piero Anversa situation first made news or at least when you first heard about it? In the public domain, it was back around April 2014. I didn’t even do a whole post on it, but rather it made two bullet points in a post about a set of bad overall news including the latest

STAP is back? Really? No, I don’t believe so, but there’s an interesting development and twist on the STAP cell front. Just a few days ago on January 4, 2017 Dr. Charles Vacanti, the originator of the STAP cells concept, submitted a declaration to the USPTO affirming the belief that STAP cells are real and requesting that

Haruko Obokata is most well-known for her role as first author of the now retracted two STAP cell Nature papers. These manuscripts claimed to have made pluripotent and even totipotent stem cells simply by stressing cells out with acid treatment or in other ways. Nobody else could get this method to work to create the so-called

A great new piece in The New Yorker by Dana Goodyear, The Stress Test, gives us a window into Charles Vacanti’s side of the STAP cell mess and includes recent quotes from him. It’s a long, fascinating look inside of STAP, the tangled and ultimately tragic scientific implosion that created and then brought down two Nature
Finally, Vacanti’s side of STAP cell implosion Read More »
Haruko Obokata was reportedly questioned by police in Japan today. The questioning relates to the STAP cell scandal that led to the retraction of two Nature papers. As first author of the papers, Obokata and other authors had reported that they could make IPSC-like cells simply via acid or other stress treatment. However, it is

The Japan Times has the first detailed account in English about Haruko Obokata’s new book, “That Day”. HT to blog reader Shinsakan. (update: another helpful piece on this from the WSJ). In the book, Obokata (who was widely blamed for the STAP cell fiasco) seeks to shift the blame to others according to the paper.

Haruko Obokata reportedtly has written a book that is somewhat of a memoir of her life including the STAP cell scandal. The exact nature of the book remains mostly a mystery at this point. It should be out on the 2nd anniversary of the STAP cell papers being published. Kyodo News gives some more details
