I’m hearing from multiple sources that momentum is building in Japan and even inside RIKEN itself for retraction of the STAP cell papers. This whole situation is a tragedy on so many levels and has become a no-win situation, but is it so bad at this point that retraction could possibly be the least terrible […]

I believe that social media has on the whole had a strongly positive impact on the STAP cell situation that the stem cell field has been grappling with for 5 weeks. If the STAP method is proven to be correct at some later date, which is possible, it’s almost certain that those replication efforts will

A small group of the STAP authors via RIKEN have now released a detailed protocol also available at Nature Protocol Exchange for making STAP stem cells entitled “Essential technical tips for STAP cell conversion culture from somatic cells”. This comes about 5 weeks after publication of their Nature STAP stem cell papers. 2020 update: With the 4th and

On the STAP cell front, I’ve heard several reports now that labs can sometimes see some kind of either Oct4-GFP reporter activity or pluripotency gene expression in acid treated cells, but the scientists do not seem particularly encouraged. One said that the cells gave a glimmer of interesting gene expression, but would not grow at

I don’t know about you, but this whole STAP stem cell thing has got me kind of bummed out. Last night I was thinking to perhaps stop blogging about it as the situation turns darker, but it seems like it wouldn’t do any good to ignore it. The ostrich with head in the sand approach

The STAP stem cell saga is like something out of a soap opera. Maybe we should call it “As the Stem Cell World Turns”. See the little green STAP spheres at right and imagine them turning like little worlds. One of the best pieces I’ve read on STAP was today’s article by Cynthia Fox at

How are people feeling about STAP stem cells? Lately, not great. With a whopping 790 votes in, the most ever recorded on this blog other than for our annual Stem Cell Person of the Year Award Internet polling, I’ve closed our week 3 STAP stem cell polling. The question in the polls each week have

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

Vad är stamceller? Den mänskliga kroppen innehåller hundratals olika celltyper, som alla spelar en viktig roll för vår hälsa. Cellerna gör så att våra kroppar fungerar som de ska genom att se till så att hjärtat slår, att hjärnan tänker, att njurarna renar vårt blod, att hudceller ersätts när de dör, osv. Stamceller har det

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
