What does future hold for STAP stem cells? Possible paradox

STAP-stem-cells

What will the future bring for STAP stem cells? Let’s look into a stem cell crystal ball. We are now one month out from the original publication of the papers. When we are three or six or twelve months out from their publication will independent labs have succeeded in replicating the method? It’s possible, but …

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 3.0: Patent, New Paper Problems, & Poll Plummet

STAP-stem-cells-hope-or-mirage-201x3001

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 …

STAP-stem-cells

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 …

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 …
