As we think about how much of a role belief should play in the hard sciences such as cell biology, a supposed cell type called VSEL or very-small embryonic stem cell-like cells comes to mind. For these guys it seems to me that the ratio of data to belief isn’t great. VSELs have nine lives. I […]

Are there endogenous adult heart stem cells that are useful in cardiac disease or can stem cell infusions help ailing hearts? As to the first question, the adult heart does not appear to have meaningful numbers of true stem cells. Further, testing the idea of infusions of stem cells for heart disease has so far been giving

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

Dr. Paolo Macchiarini exemplifies how things can change quickly in the stem cell world and go from sky highs to deep lows. Stem cell rollercoasters Over the years, a few academic stem cell researchers as well as some operators in the unproven clinic sphere have had dizzying ups and downs. There’s John Kosolcharoen. His company

A few people in the stem cell field keep arguing that adult pluripotent stem cells exist, including so-called “very small embryonic-like stem cells” or VSEL stem cells. These days the supposed cells are called VSELs or V-cells too. Only a handful of researchers have ever been able to report finding and studying these cells. Others

Eight years ago two new Nature papers broke on the scene reporting supposed STAP cells with one of the senior authors, Charles Vacanti of Harvard, most well known previously for making the so-called “Vacanti mouse” along with his brother Joseph. The Vacanti mouse had a bioengineered human ear growing on its back. While STAP cells

When I read about Elizabeth Holmes and her blood testing startup Theranos I see parallels to hucksters in the arena of stem cells and cell therapy. I’m thinking especially of the unproven stem cell clinics out there. It goes farther than that though too, including people who aren’t hucksters at all but get caught up

When someone uses the term “adult stem cells” you might think that simply means stem cells from adults. However, it’s not that simple. The goal of today’s post is to help you get all the key facts about adult stem cells. This includes the different types of adult stem cells and their clinical potential. What
What are adult stem cells & their clinical applications? Read More »
What a year 2020 was, but there was still plenty of great science, which continues now in 2021 including published research like today’s recommended pieces and there’s one thread on MSCs today. The Niche new look, more features, and a Medical Advisory Board for 2021 Before we get to the recommended reads, note that 2021
