Oddest Things About Unfolding STAP Stem Cell Story

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 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 …

In a pickle over STAP stem cells: main reasons for skepticism

in-a-pickle

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, …

Big patent & IP implications or even ‘war’ from STAP stem cells?

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 …

Interview with Charles Vacanti on STAP Cells: Link to Spore Stem Cells & More

Obokata-FIg.-2a

The recent publication of two Nature papers by a team in part led by Dr. Charles Vacanti on acid treatment produced stem cells (so-called STAP stem cells) has been a blockbuster story in the stem cell field and has grabbed major global media attention as well. For background my review of the paper here and more thoughts here. Many …
