What’s the real story on adult stem cells? Do they really have little to no risk? As a self-proclaimed fan of stem cells, including adult stem cells, I often find myself writing and talking about them to a large, diverse audience. I’ve become a stem cell ambassador of sorts. However, I am also a realist …

Who discovered stem cells? It goes back further than you might think. Is it even possible that one scientific team all by themselves discovered something so ubiquitous as stem cells? In theory yes. However, after research including this in Cell Stem Cell, I believe that no one group discovered stem cells. Also, if you ask the …

Does the Vatican view the American pro-lifers as a bunch of wacky extremists? An article today certainly suggest this. What’s going on? The Vatican, Catholics more generally, and “pro-lifers”, as designated by the Catholic website CatholicCulture.org are still apparently very much at odds over a now cancelled Vatican conference on stem cells that would have included …
Why aren’t there are super pygmy vertebrates? For most vertebrate animals, their early embryonic development unfolds in extremely congruent fashions. Embryo growth is stem cell-dependent and in large part, despite different gestational periods, the molecular and cellular machinery that controls vertebrate development is almost perfectly conserved. Yet at maturity vertebrates end up with a range …
Cancer invokes powerful feelings so it is not surprising that there are a lot of harmful myths and urban legends out there about it. As a cancer researcher and cancer survivor, I can see it from both the biomedical research side and the patient side. Here’s my top 10 list of myths & legends about …

You can learn more about the FDA’s view of and concerns about stem cells here and here. …
A recent article in Nature News about a stem cell transplant company called Celltex got me thinking again about safety. The safety of stem cell-based therapies is kind of an obsession of mine. A question comes to mind. Are people realistic about what stem cells can do for them and the risks involved? The answer …

The use of stem cells for cosmetics and cosmetic procedures is exploding even while many important questions remain. How legitimate are these stem cell cosmetic products and procedures? Are they safe and effective? What kinds of medical conditions are they being used to treat? I also recently did a post on another area of medicine …
Lately I have been critical of an ultra-conservative political think tank-like foundation called the Witherspoon Institute. They have recently joined the federal lawsuit as friends of the plaintiffs suing to stop federal funding of embryonic stem cell research. The Witherspoon Council has just published a 100+ page report on stem cells in the very conservative, somewhat obscure …
