I’m tracking opinion in the world of stem cells on STAP cells, those acid-induced stem cells reported in Nature. I’m hoping to capture potential dynamic changes in people’s views as the STAP stem cell situation evolves. Even if you’ve voted in my past polls, this is a new one so you can (and please do) […]
Do You Believe in STAP Cells: Poll Week 3 Read More »
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

It is important for the stem cell field to gain clarity on STAP 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 engage

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

Acid-induced pluripotent or even totipotent stem cells, called STAP 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 STAP?

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

This is a crowdsource page for people who want to post their findings on their attempts to validate the STAP stem cell ( ＳＴＡＰ細胞) method. I’m going to color successful or even moderately encouraging reports green and failures/discouraging results in red. *For those with longer attention spans, see some additional important considerations for this crowdsourcing effort at
Update: I’ve set up a STAP new data page where people can share their results, thoughts, etc. The report of STAP stem cells has shaken things up. The idea that you can easily make powerful stem cells with a simple acid treatment or other sources of cellular stress has definitely caught the attention of the world of

If you take an ordinary cucumber and soak it in a mild acid solution of vinegar for a few weeks you get a pickle, which is where we find STAP stem cells. Recently, some scientists reported in Nature that if you take ordinary cells and soak them in a mild acid solution for 30 minutes,

A new article in the major Japanese newspaper, Asahi Shimbun, just came out suggest major intellectual property (IP) and patent issues related to stem cells including the new stress induced STAP stem cells. The piece is entitled provocatively enough “Global patent war looms with epoch-making discovery of STAP cells“. That’s strong language. The article begins
