Weekly reads: H3.3 on the brain, Texas bill, HSCs

H3f3a, histone H3.3, knockout

It’s always exciting when your lab has a new paper and my team just published a study knocking out the H3f3a gene in mice, which codes for histone H3.3 protein. We found that loss of this gene leads to lethality at a late stage of embryonic development. There were also indications of more specific phenotypes …

Does Medicare cover stem cell therapy? Mostly no & it’s poised to recoup tens of millions

Regenative labs, does Medicare cover stem cell therapy?

Does Medicare cover stem cell therapy? Readers of The Niche have regularly asked this question. They’re curious about insurance coverage too. The answer is “no” in almost every case, with some notable exceptions I’ll get to at the end of the post. Still, clinics appear to have already been charging Medicare for what collectively adds …

2023 stem cell & regenerative medicine predictions

stem cell predictions

Toward the end of each year, I make stem cell & regenerative medicine predictions for the coming year. It’s a fun tradition here on The Niche that goes way back. The stem cell field has changed dramatically as reflected in each year’s predictions. Here’s a list of past predictions with my grades of how they …

Grading my 2022 regenerative medicine predictions

stem-cell-crystal-ball-300x3001

It’s that time of year again when I grade my previous year’s predictions for the stem cell & regenerative medicine space. Overall, I did better than a typical year. I give the 2022 predictions an A- overall. This exercise can be kind of fun but also humbling. For example, I tend to be too optimistic …

Stem cells & the philosopher’s stone, P53, thyroid organoids

philosopher's stone

I hadn’t remembered the history of the philosopher’s stone until reading a new review article about stem cells and aging. Here’s the article. Is the philosopher’s stone to rejuvenate blood stem cells an epigenetic regulator? Nature Aging. This preview kind of piece discusses how inhibiting a specific factor called PHF6 can “rejuvenate” HSCs in mice. …

Clinical utility & examples of unipotent vs. multipotent stem cells

mesenchymal cells

What are examples of unipotent and multipotent stem cells? More broadly, stem cells have the ability to do two key things. They can make more of themselves through a process called self-renewal. Also, they have the ability to differentiate into other cell types. This latter property is called potency. Taken together this means by definition …
