Vacanti Mouse

Eight years ago two new Nature papers broke on the scene reporting supposed STAP cells with one of the senior authors, Charles Vacanti of Harvard, most well known previously for making the so-called “Vacanti mouse” along with his brother Joseph. The Vacanti mouse had a bioengineered human ear growing on its back. While STAP cells …

Ear-itating: Awesome Oliver Invokes Vacanti Mouse While Blistering Dr. Oz

Mouse-support-group

Comedian John Oliver has an absolutely blistering segment (see below) on Dr. Oz in which he skewers the physician huckster. The video includes incredibly telling Oz testimony before Congress in which the celebrity doctor seems frankly pretty pathetic and cannot answer even simple questions about his selling of arguably snake oil on his show. Oz likes to …

Perspectives 10 years after STAP cells: the culture of science, misconduct, & hopes for progress

Haruko-Obokata-小保方-晴子-

Exactly ten years ago today, on January 29, 2014, I wrote about two new Nature papers on so-called STAP cells. The papers claimed that stress alone could convert regular non-stem cells into some of the most powerful stem cells. More specifically, the authors claimed to make pluripotent stem cells similar to iPS cells this way. …

Whatever happened to the STAP cell scientists including Haruko Obokata?

Obokata-game

Once upon a time this blog and major outlets around the world were regularly writing about a Japanese stem cell researcher named Haruko Obokata (小保方 晴子). Whatever happened to Obokata and the other folks directly involved in STAP cell research? First, a bit of background because maybe still a few people never heard of STAP cells …

STAP Cell Update: STAP-like paper, Real Origin of STAP cells

electric-iPSC

The STAP cell mess that began in January of this year has in some ways quieted down. In a broader sense, I believe that STAP is now and will be in the future viewed as a scandal that revealed some less than ideal aspects to the world of biomedical science and publishing. Where does this …

RIKEN Initial PR Reaction to STAP Cell Fiasco

STAP-stem-cells

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, …

Reactions to RIKEN’s STAP cell protocol

STAP-from-T-cells

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 …

Interview with Dr. Teru Wakayama on STAP stem cells

wakayama

I asked Dr. Teruhiko Wakayama, who goes by Teru to those who know him, if he would be willing to do a Q&A on the STAP stem cell situation. Teru was senior author on the STAP stem cell Nature letter on chimerism, but was not a senior (note this is a correction from an earlier version of this …

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, …

Review of Obokata STAP cells Nature papers

STAP-stem-cells

In two Nature papers (here and here) published today researchers report the astounding finding of reprogramming differentiated cells back to a pluripotent or even totipotent state simply by exposing the cells to extreme environmental stress, creating cells they called STAP cells. Update: see more thoughts on STAP stem cells here. STAP cells: stressing the cell …
