A firm called Kimera labs just received an untitled letter from the FDA. The firm has been supplying non-FDA-approved exosomes to various customers including at least one stem cell clinic without sparking any obvious action from the agency, but on April 10th that changed with the letter, which in my view is quite serious. What […]

Last year an odd pub made the big claim that the interstitium is a new organ. I didn’t buy that. Now an over-the-top stem cell advertisement that recently ran in the San Diego Union-Tribune (U-T) is piggybacking off of the supposed “interstitium as new tissue” claim to make all kinds of other claims about some

The 60 Minutes show here in the U.S. has done sobering segments over the years on risky, unproven stem cell clinics, but now there is a new episode of 60 Minutes Australia that is the polar opposite: it mostly made a mess of things with its fluffy coverage of the story of a wonderful little

Three recent media pieces on unproven, for-profit stem cell clinics paint an unflattering picture of this industry. At the intersection of these pieces is the clinic “treatment” consisting of fat stem cells (being manufactured as in a screenshot at right from a clinic YouTube video), a product the FDA has indicated is most often going

About once each year or two, I try to schedule what I call a “big picture” lab meeting where my lab and I discuss major issues related to being a scientist. Also, I try to answer their questions about just about anything. In my lab we rotate between various lab meeting formats and also have

What is stem cell media? When us scientists hear the phrase “stem cell media” we usually think about the liquid food that we feed our stem cells in the lab, which resembles a kind of nutrient-rich Kool-aid, but another kind of stem cell media consists of the news coverage of stem cells. This other kind

Science hype is one of the more troublesome issues in our field today especially at its interface with the media, and unfortunately a ‘great’ example of that came this past week in a headline from the Daily Mail on the new CRISPR of human embryos paper from Kathy Niakan’s group in the UK. Although Niakan’s

Science hype deserves negative attention for the harm it does including both to science itself and to patients. I’ve seen two really egregious examples of hype lately in science headlines. First from the Washington Post comes a stem cell story with a very hype-ful title: Stanford researchers ‘stunned’ by stem cell experiment that helped stroke

One of the biggest claims related to stem cells and in particular to induced pluripotent stem cells (IPSC or IPS cells) of 2015 came just yesterday about growing a human fetal brain. A press release from Ohio State University reports that two of its researchers had grown a nearly full-formed human fetal brain. My initial reaction

A hot topic in biomedical sciences is converting white “bad” fat into brown “good” fat. The latter type of adipose is viewed more positively because it seems to be associated with a relatively metabolically more active, leaner state. Could we somehow convert white adipose to brown adipose and in so doing have a beneficial effect
