Every year I make stem cell and regenerative medicine predictions. Looking at my predictions for 2023, they reflect a wild year but in many ways a good one overall. Below I have graded my 2023 predictions. Overall, my crystal ball gave solid results. Some of the predictions have been condensed to keep things concise, but you […]

It feels like we are marching towards a future in which key aspects of human reproduction, including the use of artificial wombs, could be substantially different than for most of history. The FDA is considering allowing a clinical trial for use of artificial wombs in people. Human trials of artificial wombs could start soon. Here’s

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

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
