Are STAP Stem Cell Nature Papers Compromised?

LOW-RES-credit-Haruko-Obokata.jpg

Are the Nature STAP stem cell papers compromised? Could Nature‘s investigation conclude with something as serious as retraction or rather a mild slap on the wrist? Somewhere in between? (note you may find this update post from 2020 to be of interest: Whatever happened to the STAP cell scientists including Haruko Obokata?) Why is this question …

STAP stem cell update 2.0: method isn’t working so far, investigations & more

LOW-RES-credit-Haruko-Obokata.jpg

Today may be a turning point in the STAP stem cell story. Nature itself opened up in a newsy piece about the events that have occurred in the past couple weeks since they published two related papers on acid/other stimulus-induced powerful pluripotent or totipotent stem cells (aka STAP stem cells). Update: Science also published a …

STAP stem cells week 2 poll results: more uncertainty

Obokata-FIg.-1

I’ve been doing polling on people’s views about STAP stem cells. You can see the week 1 poll results here. I’ve just closed the week 2 polling and the results are above. In week 1 while there was a significant split between respondents, the polling leaned clearly toward people being more positive about STAP stem …

Note on policy on commenting and how it relates to STAP stem cell situation

Haruko-Obokata

It is important for the stem cell field to gain clarity on STAP stem cells. For this reason it is reasonable and at times helpful to critically discuss the data, past findings, concerns about elements of publications, and such. However, it is not helpful and is in fact against the policy of this blog to …

STAP stem cell update: more prelim data, missing data, & 2011 paper problems

PH-STAP-test

What’s the latest on the now two-week-old STAP stem cell saga? More preliminary data from around the world.  People continue to deposit their data into our crowdsourcing page with 8 reports so far and I know some of them are from top-notch labs. Only one of them is even slightly encouraging with a report of …

Latest developments and scoops on STAP stem cells

stap-stem-cells-fetus-300x2251

Acid-induced pluripotent or even totipotent stem cells, called STAP stem cells, have thrown the stem cell field for a bit of a loop. For more background see my interview with the key public face of STAP, Dr. Charles Vacanti, as well as my review of their paper, my top 5 reasons for skepticism, and some other thoughts. Do you believe in …

Do you believe in STAP stem cells new poll: week two

STAP-cells-300x300

I’m interested in tracking potential dynamic changes in people’s view of STAP stem cells. So about once a week I’m going to start a new poll on the extent to which you readers believe in them. Below is week two’s STAP poll. So if you’ve voted in the previous poll (which garnered more than 500 responses) you …

STAP stem cell poll: interesting results & regional differences

I’ve been doing a poll on the extent to which people believe or do not believe in the stress-induced STAP stem cells reported in Nature last week. In just a few days of poll, we’ve got almost 400 respondents, which is great. It’s still not a scientific poll, but the results (above) are interesting for …
