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 […]
Are STAP Stem Cell Nature Papers Compromised? Read More »
People have been taking a long look over the last 24 hours or so at the STAP stem cell patent application filed by Charles Vacanti, his brother, Obokata, and others. Any reactions? I don’t know much about patents so I’d be curious of your impressions. New STAP paper troubles? I’m hearing through the stem grapevine

What’s the latest surprise on the STAP cell front? There have been many unexpected turn along the way in the past few weeks of the rollercoaster ride the stem cell field is on related to STAP stem cells, the super powerful stem cells reportedly (in two papers in Nature) made “simply” by exposing cells to

We know quite a bit more about the Nature papers on stress-induced STAP stem cells than we did just a couple weeks ago when they were published, but there are many crucial outstanding questions too and odd things that remain unresolved. Below are my top STAP stem cell oddities. 10. Dr. Vacanti says that STAP

Today may be a turning point for STAP cells. 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 news piece on

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)

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

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
