I would guess that Nature is mulling over retracting the other article editorially?? How can they not?
I guess Nature will wait to see the first Niwa's report.
From NATURE NEWS BLOG "Lead author agrees to retract controversial stem cell paper"http://blogs.nature.com/news/2014/05/lead-author-agrees-to-retract-controversial-stem-cell-paper...
It seems they will finally retract this paper. http://english.kyodonews.jp/news/2014/05/292789.html?utm_source=dlvr.it

I agree that the blood vessel pattern on the head is superposable as Unreg has shown. For non-experts such as myself, could I ask whether there is normally some variation between mouse embryos, for…
-Regarding point a) "The panels are mentioned in the legends, so what "reference" is missing?" I think they refer to the fact that in the text of the paper there's no mention (reference) to the…
Sorry, now I see your point.
@ Unregistered: ( March 8th, 2014 3:00pm UTC )If you read the comment and figure legend carefully, you will find that the images are supposed to be from two different embryos (for both of which…
The images are supposed to show identical features. They are brightfield and fluorescense of the one and same embryo. There is nothing strange as far as I can see...
In fact, a newspaper interpreted the interim report as accepting that the images were duplicates included in error (http://www.latimes.com/science/sciencenow/la-sci-sn-riken-finds-mistakes-but-no-inten…

@Peer5 would you mind posting an image somewhere so we can see what you're talking about?
Copy figure 1 to Photoshop. Then do 'invert color'. Compare the head vasculature of the control embryo (ES chimera, top panels bright field
In addition to evaluating the likelihood of two embryos having sufficiently similar patterns of blood vessels, one should also consider the chances of the images falling in essentially the same plane.
Whoa!! You're right the vasculature in the head of the control and experimental embryo is identical!!

I agree with Unreg@3:29pm. I don't see a difference. Because they don't document the exposure times I guess it could be that the original exposure was 1 sec and the long one was 1...
Does anyone know what the above Unreg (@ February 28th, 2014 7:06am UTC ) is talking about? I have examined the posted image and the FACS profiles...
It's not dramatic, but I can see a difference in intensity.
Figure 1a of this paper has panels of short and long exposure images of the same sample. But there is no difference in the signal intensities of placenta...

Wakayama is quoted as saying that these were two images of the same embryo taken from different angles - an admission that the placenta is the same, in other words...
Week 2 polling on STAP stem cells is now up on my blog and reflects more uncertainty: http://www.ipscell.com/2014/02/stap-stem-cells-week-2-poll-results-more-uncertainty/
@UnregisteredThank you for the image providing "better understanding". Indeed It does. Even so, it seems to me that the key feature of these two images has - so far - not been made explicit...
"At this point in time, our judgment is that the research findings are solid," a Riken representative commented.

WOW! This two images are strikingly similar!
I looked at them at high magnification. They look alike but I do not think it is similar to each other.
The parts of placentas of Fig.1b (Long exposure) and Fig.2g (cag-GFP) in this paper were very similar to each other.The image of Fig.1b is for the chimaeric fetus derived from the STAP cell...
