Are small clusters of cells that make up 5-day-old human embryos equivalent to children? Biologically and in terms of just common sense, the answer is “no.” These tiny spheres have around 100 cells and no organs. Actual people have many trillions of cells, brains, and other organs. Alabama law on embryos may block IVF About …
Retraction Watch has been a great resource for those of us who have been following research misconduct. They widely cover and conduct research on retractions, corrections, and other developments in this space. Unfortunately, there’s been plenty to write about even just within the stem cell and cell therapy arena, which is my primary interest. Think …
The Bay Area biotech Conception Bio has an intriguing name. What does “conception” mean here? Scientists can make many things from stem cells. For example, lately I’ve written a lot about stem cell-based human embryo models. Another intriguing area is called in vitro gametogenesis or IVG, where Conception Bio is a leader. IVG means making …

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 …
How much does stem cell therapy cost in 2024? How have prices changed? To authoritatively answer these questions now we need data from the present and past along with expert perspectives. Some surprises come up in this new analysis. In this article Intro | Stem Cell Therapy Cost: $10,000-$20,000 | Why do stem cells cost so much? …
Totipotency literally means all powerful, but it refers in biology to specific cells. These cells can make every type of cell in the body of an organism plus the extraembryonic tissues needed for development. This includes humans. So if you could reprogram human cells like blood or skin cells into totipotent stem cells, you might …

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. …

It’s a big challenge to get a cell therapy approved by the FDA and if you look at my list of FDA-approved stem cell therapies, it’s not as long as we might hope. FDA OK on cell therapy from Gamida Cell For this reason, it was excellent news to see that the FDA approved a …

Are there any guidelines for genomics studies of famous dead people like sequencing their genomes? It doesn’t seem like it. I remember when I first heard of the idea of trying to clone John Lennon from an old molar. Fortunately, as far as I know no one ever tried that, but it wouldn’t surprise me if …
Someday could human brain organoids get to the point of having organized human-like thoughts? Even consciousness? The more time passes, the less likely I think this is. It’s not impossible, but brain organoids have big limitations in that regard. To be clear, I don’t mean brain organoids having some vaguely human brain-like electrical activity. Even monolayers of …
