An FDA FOIA dump of text messages of former Commissioner Stephen Hahn suggests that a Texas regenerative firm called Direct Biologics benefited from political pressure on him in mid-2020. Then he was asked again to help in early 2021. This was shortly before he resigned at the start of the Biden Administration. The push came from […]

A new stem cells for ALS treatment trial represents a big step forward. It’s early days still but this trial shows feasibility and provides a helpful foundation for moving forward. It also highlights challenges. The work is from a team led by Clive Svendsen. Stem cells for ALS treatment trial Here’s the study. Transplantation of
It was a shock to learn today that New York Stem Cell Foundation CEO and Co-Founder Susan Solomon had passed away yesterday after a long battle with ovarian cancer. I met Susan a few times over the years and was always struck by her positive energy. At a practical level she got big things done

The big news of the week was the big FDA stem cell in court by Judge Jesus Bernal here in California, who ruled in favor of a chain of stem cell clinics called Cell Surgical Network. The FDA had been seeking an injunction against the clinics. I believe the ruling was founded in part on

Exosome therapy is a still-experimental cell therapy approach aimed at treating specific diseases using secretions from cells. It’s novel since most attention on cell therapies has been given to using the actual cells themselves. In addition, this approach is a newer idea than using cells as the drug to treat diseases. Interestingly, the term “cell

Does aging do something to time so it seems like as you get older that time goes by faster? Remember as a little kid when summer seemed to last forever and car rides could be agonizingly long? I’ve heard two theories on this. One is that the brain’s baseline of activity slows down with aging

Histone proteins such as histone H3 are often popping up in science writing and news sometimes includes specific modified forms of H3 including one that we scientists call H3K27me3. What is in this article What is H3K27me3? | The histone code | H3K27ac and H3K27me3 function | H3K27 and human disease | References The goal of today’s post

I have a soft spot for fibroblasts, perhaps because one of the first immortalized cell lines I ever grew was NIH3T3. These are mouse fibroblasts that have been immortalized. They are very useful for a variety of experiments. I used them to study an oncogene called E2A-PBX1. Experience with fibroblasts including 3T3s I was amazed

I took a cross-country road trip earlier this month that was pretty amazing and barely thought about stem cell research for the first time in years. We did run across one stem cell clinic in Florida by accident. I’ll write about that trip soon, but first we have our weekly reads including some very cool
