Burst Biologics unapproved biologic used by Weill Cornell: was there a cover-up?

Burst Biologics, Christopher Jones

The New York Times just broke a story on Burst Biologics and Weill Cornell that fits with long-standing troubling questions about regenerative biologics producers. The story also bears on the doctors and hospitals like Weill Cornell that were or are customers of the suppliers. Further, what is the FDA’s role in all of this? The …

He Jiankui proposes editing human embryos again

He Jiankui

It wasn’t that long ago that Chinese scientist He Jiankui got out of jail. Why was he in there? For doing unauthorized human CRISPR to make heritably gene-edited humans. He botched that and apparently forged some approvals to make it happen. The three children involved may have life-long health problems as a result. I wrote …

Questions on National Academies in vitro gametogenesis (IVG) meeting sponsorship

in vitro gametogenesis, IVG

Research on in vitro gametogenesis or IVG is jumping ahead and such work could one day lead to new infertility treatments. In vitro gametogenesis is the process of producing gametes (sperm and eggs) from stem cells. Those powerful stem cells, called iPS cells, can be made from ordinary adult cells like skin or blood cells. …

bat stem cells, stem cells

Occasionally when I write a post there is an angry reaction to it in the blog comments, which was the case for my recent fact-check of the LifeWave X39 patches.  As you can see in that post, I didn’t find convincing data to either back up the claimed stem cell connection. In my opinion, there …

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 …

Kevin McCormack, Paul Knoepfler, stem cell research

Out of the blue this past week we lost Kevin McCormack of CIRM to a heart attack. When I first heard, my reaction was that can’t be, but it is. About Kevin McCormack If you aren’t familiar with him, Kevin was officially Director of Patient Advocacy at our state’s Stem Cell Agency. However, he was …

2nd chances after big misconduct? He Jiankui, James Wilson, others

James Wilson, Gene therapy

There have been rare instances like with scientist James Wilson where researchers were involved in what I would call major misconduct but somehow managed to bounce back. In a sense, they were given second chances in part by regulators but also by other scientists or supporters. However, after extraordinary misconduct, especially contributing to the death …

NIH 3T3 fibroblasts ATCC

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 …

Overplaying N=1 in the stem cell therapy world

stem cell therapy

The regular emails and phone calls I get from patients asking questions about stem cell therapy are a powerful reminder of the fact that research in our field can be very personal. Sometimes individuals who receive experimental stem cell therapy (or other cell therapies) and seem to have a positive outcome can end up becoming …

HIV infected T cell, HIV cure

The idea of stem cells outright curing diseases is exciting and has powerful appeal, but media need to be careful about using the word cure in headlines and articles as we saw this week related to a possible HIV Cure. HIV cure via stem cells and chemo? The big news of the week was that …
