STAP Voted as the Stem Cell Story of the Year for 2014

Stem-Cell-Story-of-2014

When I asked the readers of this blog what they felt was the biggest stem cell story of 2014 in a poll, they overwhelmingly picked the STAP cell scandal. For background on STAP you can toggle through the many STAP cell pieces on this blog here, see a STAP timeline, and a STAP image gallery. Basically, …

STAP Cell Update: STAP-like paper, Real Origin of STAP cells

electric-iPSC

The STAP cell mess that began in January of this year has in some ways quieted down. In a broader sense, I believe that STAP is now and will be in the future viewed as a scandal that revealed some less than ideal aspects to the world of biomedical science and publishing. Where does this …

STAP papers blistered by Nature’s own reviewers were then accepted

STAP-magic

The reviews of a STAP paper submitted to and rejected by the journal Science in 2012 were posted at Retraction Watch yesterday. They filled in some gaps in the puzzle of the series of events that led to such flawed science being published in Nature in January 2014, but the reviews also raised more questions. Today, more STAP paper …

Full Reviews of Rejected STAP Paper Point to Early Signs of Big Trouble

Before the two STAP cell papers were published in Nature in January of 2014, much of the same data was reportedly submitted as single papers to other high-profile journals including Science. In these cases, the proto-STAP papers as we might call them were rejected. But why? Until now we largely could only speculate. However, the reviews …

RIKEN fails to reproduce STAP, big CDB shake up expected

STAP-stem-cells

Nikkei is reporting that the RIKEN internal attempt to replicate so-called STAP (acid bath) cells has failed. Update: apparently, although RIKEN calls the efforts preliminary, the team tried to make STAP an amazing 22 times and 22 times it failed. The rumors for weeks in the stem cell gapevine that RIKEN itself could not get …

Where does STAP cell mess go from here & key unanswered questions

STAP-stem-cells-hope-or-mirage

In some ways it’s hard to imagine that it was only just over 6 months ago that Nature published the two STAP papers by a collaborative team of Japanese and American researchers. It feels like years have gone by since then because so much has happened related to the STAP mess including the retraction of …

Obokata OKs Retraction of Nature STAP Cell Letter, Not Article

Obokata-press-conference

Japanese news media are reporting that Haruko Obokata and other key authors have agreed to retract the Nature STAP cell letter, but not the Nature article. This is a major development and a peculiar one because to many in the  field it is the Nature STAP cell article that is the more flawed of the two Nature papers on STAP. Why would …
