Meet The Screamers. After being a scientist in one form or another for 30 years and blogging about stem cells and other science for more than 10 years, I’ve seen a lot of science hype. However, some science hype goes above and beyond the usual level to outright smack readers in the face. It almost hurts your brain or makes you want to scream “No!” We definitely see this kind of uber-hype in the stem cell field at times, but also in many other …Read More

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 sparked it? My sense is that a major trigger was Kimera Labs being linked some weeks back to an experimental infusion of exosomes into a COVID19 patient. The letter …Read More

I thought I’d take a look again into the world of stem cell supplements since it’s been a few years. What I found wasn’t a pretty picture. (Note that “supplements” here refer to things people can ingest to somehow supposedly help their stem cells, not “supplements” that us scientists add to the media we use to grow stem cells.) Supplements in general For context, I’m fairly skeptical of supplements in general unless one has a documented deficiency in something like iron or maybe (maybe …Read More

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 mystery “stem cell” pill. You can see a picture at left of the ad that a The Niche reader sent to me. The word “cure” there is like a …Read More

Swedish Medical Center in Seattle is now marketing regenerative medicine therapies including some things that in my view are not really scientifically proven to work including via an infomercial. This is part of a bigger trend where more legit medical centers have begun selling regenerative medicine “treatments” that are still being developed. Sometimes they even engage in questionable marketing of this stuff too. The latest entry here is unbelievable in some ways. In the above segment sponsored by Swedish Medical Center on a show …Read More

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 girl with cerebral palsy receiving an unproven stem cell transplant at a clinic in Mexico. The new show segment, which you can watch in two parts (see below) on …Read More
