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.

If you remember xenobots, mobile clusters of frog cells, now you might be interested to learn that some of the same team brings us human cell clusters called anthrobots. Both frog and human cellular clusters are considered types of biobots or robots made of cells. To me, anthrobots seem akin to human organoids or assembloids.

I hadn’t remembered the history of the philosopher’s stone until reading a new review article about stem cells and aging. Here’s the article. Is the philosopher’s stone to rejuvenate blood stem cells an epigenetic regulator? Nature Aging. This preview kind of piece discusses how inhibiting a specific factor called PHF6 can “rejuvenate” HSCs in mice.

I’m working to send out a big grant on Tuesday so I’m busier than ever but a few stem cell and regenerative medicine stories caught my eye. I can’t write grants 24/7 without a few breaks although sometimes it feels like that’s what I’m doing. Bat stem cell derivation Pluripotent bat stem cells as a

As I’ve mentioned recently, it’s my busy time for medical school teaching and not long ago we did a GI lab that included one of my favorite structures in the course: taste buds. Taste buds The medical students seem fascinated with taste buds too. I can tell as their professor when something is particularly interesting

It’s been quite a ride doing this blog on stem cells and other technologies for more than a dozen years. So far it seems like I’ll keep it going. A large part of the reason is because of people needing good information about our field. Those people include scientists and physicians but also many in

Sometimes a paper really catches your eye like a new Cell Stem Cell pub reporting eye-like structures grown on brain organoids. The paper is Human brain organoids assemble functionally integrated bilateral optic vesicles. Let’s take a quick look at this paper, its context, and the potential big-picture implications. Brain organoids with “eyes”? At first glance,

It’s been a little quiet here on The Niche for the past week as I was off in Yellowstone National Park, but I’m back with this week’s recommended weekly reads including a section on organoids. First, I want to share a nature pic from the trip. A highlight was encountering a badger in Lamar Valley

This was an unusual week in that three papers in a sense collided together related to embryo production and growth, raising new research possibilities but also serious ethical questions. New research: what is an embryo & what is not? The first two Nature papers reported generating the most realistic models of human embryos from scratch
