A paper has been published reporting that repeated attempts to make so-called “acid bath stem cells” have failed. At the end of January it was claimed in two Nature papers that a mild acid treatment created pluripotent or even totipotent stem cells that that the authors termed “STAP cells” or “STAP stem cells” (collectively referred […]

Parabiosis and aging When it comes to anti-aging science, creepy meets cool with “young blood” in new blood mixing studies just published. The researchers report that blood from young animals literally makes older animals younger. That striking claim is made by both of two independent teams. They published high-profile papers that just came

The future is now. Or so goes the expression. For CIRM, it rings true today. Last year I blogged about what we might expect from the new CIRM that would evolve and take form in the future. I was particularly thinking about this coming incarnation of CIRM, which I called CIRM 2.0, as it related

What is Human SCNT? A new human therapeutic cloning paper is out today, the third in a matter of months. This one is from the lab group of Dr. Dieter Egli published in Nature demonstrating production of nuclear transfer embryonic stem cells (NT-ESCs) from an adult human somatic donor via somatic cell nuclear transfer (SCNT). This

The ultimate fate of the two Nature STAP cell papers remains in troubled limbo. One of the senior STAP cell authors, Dr. Sasai, held a news conference yesterday in Japan that included a call for the papers to be retracted. He was variously quoted as believing in STAP cells or alternatively as just thinking it

What’s going on with the STAP cell situation now that it is into its third month? It’s getting worse instead of better or clearer, at least in part due to RIKEN’s incomplete investigation. What’s going on with STAP? New RIKEN Press Conference RIKEN reportedly held an odd sort of limited press conference today that TJO

Yesterday was a crazy day for the STAP cell situation. We had RIKEN releasing a scathing internal investigatory report and then some folks in the media got all worked up about a single PCR assay result that Dr. Ken Lee posted on ResearchGate. Some of the reporters/science writers hyped their headlines/articles on this situation as though

RIKEN Institute in Japan has formally announced the complete findings of its investigation into the STAP cell research, Haruko Obokata, and Nature papers. RIKEN almost entirely blamed Obokata for the STAP mess in this report and they didn’t mince words. The RIKEN report alleged that Obokata had engaged in two instances of “research misconduct” as

What next for STAP? Is retraction of the two papers on the near horizon? It has been two months now since Nature published the two papers on STAP cells and STAP stem cells. There has been a storm of controversy surrounding these papers and the claims they made to easily produce the most powerful of

Dr. Ken Lee’s lab has done some very important validation attempts on STAP cells and has posted them on ResearchGate. To my knowledge, his lab’s STAP experiments are the ones in the public domain that most closely matched the methods of the Nature STAP papers. Dr. Lee submitted the work to Nature Brief Communications Arising
