EXCLUSIVE: Nature reviewers not persuaded by initial STAP stem cell papers
As two discredited, and now retracted, stem cell papers have produced an
almost unimaginable fallout—a national hero accused of scientific fraud,
the revamping of one of Japan’s major research institutes, and the suicide
of a respected cell biologist—researchers have privately and publicly asked
how Nature could have published work that, in retrospect, seems so
obviously flawed.
Another piece of the puzzle has come to light. The Science news team
received a copy of email correspondence between a Nature editor and Haruko
Obokata, the lead author of the papers, that indicates the work initially
received as rocky a reception there as at two other journals, Cell and
Science, that had rejected the work previously. The email, dated 4 April
2013, includes detailed separate criticisms of the two papers and
suggestions for new data to support the authors’ claims of a simple and
novel way to make stem cells that could form the myriad cell types within a
body. The Nature editor rejected the papers, but left open a window, writing
, “Should further experimental data allow you to address these criticisms,
we would be happy to look at a revised manuscript …” The two papers were
published 10 months later.
A spokesperson for Nature declined to comment on the email correspondence,
or how Obokata and her coauthors revised their manuscripts. But the
critiques are similar to those Science reviewers reportedly leveled when
considering an earlier report on the work. Yesterday the website
Retraction Watch published what it says are the cover letter and reviews for
a manuscript on stem cells submitted to Science by Obokata. (Science’s
editorial department would not confirm that the reported reviews were
genuine, but the news staff has received the identical document from an
independent source.)
The Nature reviewers call the manuscripts and the results they describe “
very interesting,” “potentially groundbreaking,” “highly provocative,”
and “truly remarkable.” In the papers, Obokata, who works at the RIKEN
Center for Developmental Biology (CDB) in Kobe, and her coauthors claimed
that bathing blood cells from newborn mice in a mildly acidic solution could
prompt them to become powerful stem cells. They dubbed the phenomenon “
stimulus-triggered acquisition of pluripotency,” or STAP.
All three Nature reviewers concluded that the data presented in the
submitted manuscripts were not enough to support such radical claims. “I
would recommend the authors to be extremely cautious in their claims …. The
authors should look into the actual effect that the treatment elicits in
the genome and they should assess genomic instability,” one writes. “There
are several issues that I consider should be clarified beyond doubt because
of the potential revolutionary nature of the observations,” writes another.
Foreshadowing the difficulty the study authors have had in providing a clear
protocol for others to replicate their work, one Nature reviewer writes, “
Of paramount importance for the legitimacy of this paper is that the authors
provide a full step by step account of their method such that the community
can rapidly validate the reproducibility of the findings. The present
method description is minimal and key elements are not properly defined.”
The reviewer notes that the methods mention the use of B27 medium, “but B27
is a medium supplement, not a medium itself.” Nor does the manuscript
mention whether any measures were taken to control the final pH, the
reviewer writes.
Since the papers were published, labs around the world have tried but failed
to produce STAP cells. The papers’ authors have posted several different
protocols online, including one as recently as 3 September.
The reviewers all point out significant inconsistencies and holes in the
data. One notes that although a chimera was supposedly made with STAP cells
from a strain of black mice, the offspring are not black. “Please explain,
” the reviewer writes.
One reviewer summed up, “As it stands, and whereas this reviewer does not
doubt the data presented, the process can be summarized as a “magical”
approach and none of the conclusions related to the “next-generation” or
amplifications in regenerative medicine is supported experimentally.”
On 1 April 2014, almost a year after the rejection notice, a RIKEN
investigating committee concluded the papers were marred by falsification
and fabrication and judged Obokata guilty of research misconduct. Other
authors were spared the misconduct charge, but the committee said that
senior authors who failed to verify the accuracy of the data “bear heavy
responsibility for the research misconduct that resulted from this failure
on their part.” RIKEN leaders have recently announced the radical
restructuring of the RIKEN CDB, cutting the staff by half.
It is still not clear what happened between 4 April 2013 when Nature
initially rejected the papers and 20 December 2013 when they were accepted.
Teruhiko Wakayama, a co-author formerly at CDB now at the University of
Yamanashi in Kofu, says that Obokata shared the reviewers’ comments with
him and he made suggestions for revisions pertaining only to the chimeric
mice experiments, which were his responsibility. He says he has no idea if
the revised papers were again sent to reviewers.
Wakayama says it might be a good idea for journals to send reviewer comments
to all co-authors as another safeguard against problematic papers. “
However, most co-authors just contribute to one or a few parts of the
experiments,” he says. This means that even if all co-authors receive the
reviewer comments they might not be in a position to address identified
problems.

Nature是该被舆论监督一下了。
作为一个高端杂志，这么疯狂追求影响因子，片面讲究热点，甚至为了引用有意向有带
大数据的文章倾斜，实在是很掉价。
Nature现在就像科学杂志里的腾讯，在哪里伸一抓都会把别人饭碗挤掉。
让他们这样一个商业集团垄断市场，对科学长远的发展是不利的。
