Before we dive into the weekly reads, I wanted to explain something new on The Niche and ask for your support of our brain tumor research.
Brain tumor research funding
As many of you know, some firsthand, funding is extremely difficult to get these days. This is particularly true for NIH funding. Some NIH institutes are only funding 4-5% of applications. Foundations supporting brain tumor research are also getting more applications than ever without increases in what they can fund.
For these reasons, I’m asking for you to consider helping support my lab’s work on brain tumors including our main efforts on childhood glioma. These glioma, whose cells have some stem cell-like characteristics, are essentially 100% lethal even with intense treatment. The kids and their families need hope, and we’re working on potential novel therapies. One of our previous findings was that specific transcription factors normally involved in brain development (e.g., ASCL1) seem to be co-opted by these glioma to drive the tumor’s development and deadliness.
The new thing here on The Niche is the stem cell image at the top right of the page, which you can click to make a contribution to help the research. Thanks for considering this.
On to our recommended reads.

Prasad is out again
I’m sure many of you remember that when Vinay Prasad first joined the FDA as CBER director and in two other roles, he didn’t last long. But then he was back pretty quick last year. Now, he’s reportedly going to leave again per WSJ: FDA’s Controversial Vaccines Chief Will Leave the Agency. It’s not a shocker given the controversy he has stirred, but still it seems unprecedented in FDA history to have someone come and go twice in a short period as a branch leader.
A top official’s departure was one of my regenerative medicine predictions for 2026. Some faulted Prasad for being an obstacle to FDA approvals, including for rare diseases. To me, another big issue was the unpredictability tied to him. I hope that Prasad’s departure could lead to more stability on biologics, but we’ll have to see.

Human stem cell-based embryo models (SCBEM) are steadily becoming more like real embryos. They are still some hurdles, but tech advances like growing the models inside of endometrial tissue are likely to make the models much more similar to real human embryos. There’s a lot to consider here.

Peptides could be one of the top health problems for years to come. It’s important to be a voice of reason on this front. Apparently we are likely getting very close (perhaps within a week or two) to an RFK Jr./FDA announcement on unleashing many of the risky, unproven peptides. There’s no good reason to do that.

There are interesting details on the Wharton’s jelly paper you linked to.
The company behind it, TAM Global, I believe is the same company as cellular performance institute, probably the most well known Wharton’s jelly clinic, based in Tijuana. Appears to be another clinic ran by Americans marketed to Americans in Mexico.

One author, Ed Clay, looks like he’s the founder of TAM/CPI, and an MMA athlete. Appears to be friends with joe rogan, who mentions CPI a lot on the podcast. They also buy ads on UFC you’ll see their logo in the cage a good amount.
Additionally, one author listed, Francesco Marincola, appears to be both the editor in chief of the journal it was published in, and CSO of these companies.

If all that is accurate, it brings a few interesting questions.
Who were the manufacturers they tested?
Were they random Mexican manufacturers?
Did they test some of the more well known labs, such as CB Cells?
Since they’re selling the same product, how viable are their own cells, did they compare?
Most importantly, what was the goal of this article?
Not that it’s inaccurate or not appreciated, I just scratch my head a bit when seeing those names and the topic, especially because CPI appears to be making lots, and lots, and lots of money loading up Americans in a van in San diego and heading to Tijuana for a few days.
From what I understand typical costs are 25-50k+ per round, and treat a wide range of conditions from neurodegenerative to orthopedic.
Thanks, Jeremy. It seems like there are a lot of layers to this. I hadn’t realized.
