A simple proposal to make STAP protocols clearer 日本語版はこちら By Jun Seita Detection of a GFP signal driven by the Oct3/4 promoter was extensively used to define STAP cells in the original STAP papers [1, 2] and similar approaches have been employed by many third-party attempts to reproduce STAP cells. On the other hand, it […]

What is Harvard’s role in the STAP cell mess? If you have been living in a cave somewhere for the last 6 weeks, to catch you up to speed, an international collaborative team published two papers in Nature reporting the creation of powerful stem cells–so-called STAP stem cells–via a simple method of stressing ordinary differentiated

The controversial STAP stem cell papers published in Nature had authors both from RIKEN in Japan and Brigham and Women’s Hospital/Harvard. What is the RIKEN interim take on the STAP cell situation? We’ve had pretty much silence from Harvard itself on this matter publicly. Dr. Charles Vacanti, senior author on one of the STAP papers,

Why is CRISPR Cas9 gene editing such a big deal? Imagine being able to make mutations in any gene you wanted say in stem cells in a relatively simple, quick and affordable fashion? Sounds exciting, huh? Every so often a new kind of technology comes along in the biomedical sciences that is a true game

A host of problems have emerged related to the two Nature papers on STAP cells and other publications by some of the same authors. It’s only been just shy of 6 weeks since these papers came out, but doesn’t it feel like about 5 years? Where will this all end? (update in 2020: closer to

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

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

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

If you’ve been paying attention to the stem cell world, you’ll remember Woo Suk Hwang, who nearly derailed the future of stem cell research by very publically proclaiming that he had made human embryonic stem cells by somatic cell nuclear transfer (SCNT). No, this has nothing to do with Shoukhrat Mitalipov’s report of successful generation
