I’ve been more interested in histones and their modifications versus DNA methylation when it comes to epigenetics and chromatin. In part this has just been because I have studied histones so much more. For example, we have been knocking out the two histone variant H3.3 genes, H3f3a and H3f3b, now for a decade. My lab also […]

Histone proteins such as histone H3 are often popping up in science writing and news sometimes includes specific modified forms of H3 including one that we scientists call H3K27me3. What is in this article What is H3K27me3? | The histone code | H3K27ac and H3K27me3 function | H3K27 and human disease | References The goal of today’s post

What exactly is a mesenchymal cell and what does the acronym MSC stand for these days? I took a stab recently at discussing mesenchymal cells and the MSC acronym so check that out. There is a great need for standards on MSCs and the products out there being marketed as MSCs are probably in reality

Anyone with a seemingly only semi-functional nervous system now post-election might be turning to science to help their brains bounce back. Here are some of the things I’ve been reading or hope to soon. In good news for the stem cell and regenerative medicine field, especially here in California, it looks like us California voters
When a vendor of important reagents like antibody supplier Abcam charges big money, those high Abcam prices could negatively impact research in the long run. Some of the prices are so high that buying just a few antibodies could take up a small but meaningful slice of an entire R01 grant. Sky-high Abcam prices I’ve

My lab is focused in part on chromatin states in stem cells and cancer including heterochromatin. In fact, my lab’s website is chromatin.com. Heterochromatin is dense, often inactive chromatin. By H&E staining and electron microscopy, heterochromatin looks dark compared to the rest of the nucleus, largely composed of euchromatin. Toward the end of my postdoc

There has been a steady stream of encouraging data on stem cells for MS. Particularly for certain kinds of MS. A new study adds to this upbeat direction.

Imagine writing or editing an article for the WaPo about risky, unproven medical interventions for COVID that desperate patients might consider. Then you link directly to the websites selling this stuff in your article. What the heck? WaPo links to risky long COVID “treatments” By linking, you not only are driving customers to these firms,

There was a time when I thought transdifferentiation based approaches might quickly move into clinical trials. Then things kind of cooled off. We didn’t see many papers reporting methods to transdifferentiate cells. I still think that this technology, sometimes called direct reprogramming, has major potential. A new paper on making human brain cells this way got

There’s nothing quite like getting a new paper out as a scientist running a research lab so this week we can celebrate our new pediatric brain tumor study. I’ll start the weekly reads with that paper. Of course, getting new grants is amazing too but there’s more of a feel of completion after a paper
