Sharks are experts at growing new teeth from stem cells. What if we humans could grow new teeth from stem cells too? It seems like a stretch. Compared to sharks, on tooth regrowth we are biological amateurs. While humans and some other animals like dogs have only two sets of teeth in our whole lives, […]

In all the time I’ve been a scientist I never worried about American science until the last month. Even during the first Trump administration, while there were challenges, I felt like things would generally be okay. Research continued. One of my daughters and I went to the Science March in 2017 in Sacramento. We bumped

What if we could grow new teeth from stem cells to replace lost ones or fix others that have big cavities again via tooth stem cells? While humans and some other animals like dogs have only two sets of teeth — so-called baby and adult teeth — in their lives, other animals aren’t so limited. For

Years ago I wrote about how I wished humans could form a blastema, which is a special area of regeneration near an injury that drives tissue replacement. For example, when a lizard loses its tail to a pursuing bobcat, if it can regrow a new one that process will depend on a blastema. The same goes

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

The FDA just sent another untitled letter to a producer of a potentially non-compliant perinatal “stem cell” product that may be an unapproved drug. This follows past non-warning letters and/or inspection reports made public to Liveyon, R3 Stem Cell, Stemell, and others. RAPS has more on the story of the new letter here. This newest

Snopes said what about stem cells? A brief search of Snopes for “stem cells” produces some wacky claims about our favorite cells. They tackle some stem cell myths floating around out there that overlap somewhat with a post I did about 5 years ago on stem cell myths. I’ve listed below the search results on

In case you have some free time for reading this week, here’s a list containing an assortment of interesting research articles and stem cell headlines. I’ve thrown some oddballs in there too including one article from May 1983, when I was just finishing up junior high. No, I didn’t write it. And no the headline

Happy science Friday and here’s a TGIF list of recent stem cell news and papers. The FDA warning letter to Richard Burt of Northwestern related to noncompliance issues with his stem cell clinic trial for MS has dominated the news recently, but some other notable things have happened as well on stem cells and more
