This is a crowdsource page for people who want to post their findings on their attempts to validate the STAP stem cell ( ＳＴＡＰ細胞) method. I’m going to color successful or even moderately encouraging reports green and failures/discouraging results in red. *For those with longer attention spans, see some additional important considerations for this crowdsourcing effort at […]
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,

The STAP papers on making iPS like cells using acid treatment of differentiated cells really has people talking. See embryo at right made from GFP reporter STAP cells that glow green. As I said in my review of the papers yesterday, there are still some critical things we do not know about STAP cells and I

Nominations for Stem Cell Person of the Year 2013 closed last night and I ended up with a remarkable list of 30 nominees. I have included a few sentences about each one below, often taking verbiage directly from the nominator. The online voting on these nominees will start soon. The top vote getters will move
Dr. Joanne Kurtzberg is a stem cell pioneer and has advanced the development of innovative stem cell therapies including those based on umbilical cord blood. She is a faculty member at Duke where she conducts her clinical research. I recently interviewed Dr. Kurtzberg and below is Part 1 of 2 of the interview. Part 2,

It’s Friday. TGIF….although of course the stem cells will be growing, experiments going, the grants and papers continue being written, and data still analyzed on Saturdays and Sundays too in the stem cell field. Stem cells are not a Mon-Fri, 9-5 kind of universe, but most of you reading this blog know that. It seems

Are MUSE cells for real? Stem cells come in different types that vary in a key property called “potency”, but very few are pluripotent. The more potency, the greater the flexibility of a stem cell to make other cell types. Flexibility in the cellular world is power. The most powerful stem cells generally used are

Below, guest blogger, John Carbona gives us his account (including pictures) of Day 2 of the Vatican Stem Cell Meeting, which included a talk by Nobel Laureate John Gurdon. Note, you can read John’s post on Day 1 of the meeting including more great pictures here. Friday, April 12, 2012 The Second International Vatican Adult

I’ve been fortunate to interview some of the greats in the stem cell field for this blog and host debates between key players. Please note that just because I have interviewed folks does not mean I agree with them or that they agree with me. The point is to establish dialogue on key issues. As
An interesting paper just came out in PNAS reporting the apparent presence of a pluripotent stem cell population in the adult breast. The paper is Roy, et al. and is from Thea Tlsty’s outstanding lab at UCSF. I have read the paper and it seems very solid technically to me. The finding has stimulated some
