Stem Cells in Wonderland

The-White-Rabbit-from-Alice-in-Wonderland

In Lewis Carroll’s masterpiece, Alice in Wonderland, there is a wonderful passage that came to mind as I read the latest response from the self-proclaimed ‘adult stem cell researchers’ suing the government to stop federally-funded ES cell research: “I don’t know what you mean by ‘glory,’ ” Alice said. Humpty Dumpty smiled contemptuously. “Of course you

iPS cells coming into focus: not quite so similar to ESC after all

FaviconIPSCELL

Update in 2020: It seems now after all these years that the consensus in the now more mature field is that IPSCs and ESCs are nearly identical in most cases, and both have some of the same translational challenges such as teratoma-forming activity. It’s interesting to read this post from nearly 10 years ago and

Beyond naming: embryo models and the importance of public dialogue

mouse embryo models, human embryo models

Who decides what to name something new in science like “human embryo models”? Also, not to get too philosophical right off the bat, but what is the point of a name? It’s about a shared understanding of what we’re talking about. But, very often, both out in the world and in the various fields of

N-myc, heterochromatin

The proto-oncogene MYC is one of those factors studied in thousands of papers. MYC and its dimerize partner MAX are also seemingly involved in just about everything. They have crucial roles in many kinds of stem cells including adult and embryonic stem cells. One way or another MYC induction seems very helpful for cellular reprogramming

mesenchymal cells

Do many in the regenerative medicine field have favorite types of stem cells? Some seem to think there’s a tension between those working on pluripotent stem cells like iPS cells and those working with MSCs. I don’t see it that way, though. Whatever stem cells work best for a particular condition should be used and,

Multipotent & totipotent vs pluripotent stem cells, very early human embryos totipotent stem cells

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.

Xist ,auto immune disease

Readers of The Niche have asked me many questions about stem cells for autoimmune disease but the puzzle of why women get these conditions more often than men hasn’t come up before here. For instance, why is MS so much more common in women than men? It’s remained somewhat of a mystery over the years.
