I’ve been following 24 stem cell stocks for a few years. I haven’t invested in them or any others recently, but rather just find them interesting. How are these doing in 2023? Mostly not great. In some cases, it is downright disastrous. Let’s take a quick look at four stocks very much in the news over …
I’ve been thinking more about the steady stream of epigenetic clock research out there. How convincing is the research on such clocks? Do they tightly relate to human biological age? The related notion of turning back such hypothetical clocks to reverse aging is exciting but controversial. It doesn’t help that some are hyping all of …

Early during my postdoc I was primarily interested in the role of Myc genes both in cancer and in stem cells, work that later included embryonic stem cells. These cells are often called ES cells. At first I first started studying N-Myc in neural stem cells using a conditional knockout approach. However, soon after I was …

A days ago the news came about Mesoblast not getting FDA approval for its MSC product for GvHD. The MSC area has had a rough few years with various clinical trials including for COVID. The “stem cells for heart disease” arena has also had a tough time. Here’s more news along these lines: BioCardia pauses enrollment in PhIII trial …

Altos Labs is an intriguing multi-institution experiment in so-called rejuvenation research all rolled into one biotech. This relatively new entity headquartered in California has multiple Nobel laureates in the biomedical field in leadership. Even more importantly it has a large group of great researchers leading its individual research labs. This all leads to high expectations, …

Who is David Sinclair and why is he all over the media related to anti-aging efforts? This post is my effort to fact-check Sinclair’s statements in the context of the broader rejuvenation arena. In the process I also review his most recent paper from my view as a stem cell and cancer biologist interested in …

Are long telomeres better than short ones? What about older folks lengthening their telomeres somewhat or stabilizing the length? Could this counter aging? As with many things, the story is far more complicated than we might hope. For background, telomeres are special structures protecting the ends of chromosomes. I remember as a young student that …

Are there endogenous adult heart stem cells that are useful in cardiac disease or can stem cell infusions help ailing hearts? As to the first question, the adult heart does not appear to have meaningful numbers of true stem cells. Further, testing the idea of infusions of stem cells for heart disease has so far been giving …

Someday could human brain organoids get to the point of having organized human-like thoughts? Even consciousness? The more time passes, the less likely I think this is. It’s not impossible, but brain organoids have big limitations in that regard. To be clear, I don’t mean brain organoids having some vaguely human brain-like electrical activity. Even monolayers of …

What is the cell therapy for ALS called NurOwn? How strong is its potential as a treatment for ALS? I’ve been following the biotech BrainStorm Cell Therapeutics for many years. Patients keep asking me about NurOwn ALS prospects. They’re looking for hope. Today’s post is a close look at NurOwn and at BrainStorm as a …
