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 …
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. …

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 …

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 …

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 …

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 …

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 …

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 …
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 …

The last few years in the stem cell and regenerative medicine arena have been complicated in many ways. Variables like surging stem cell clinics and COVID have made predictions harder. Even so, trying to make predictions is useful and it’s fun to go over past year’s predictions. You can see my scorecard on my 2021 …
