California stem cell law

The four words “California stem cell research” go nicely together and I hope they will continue to resonate in a special way to people around the world in the coming decade. We are at a crossroads for stem cell research in California as the original form of the California Stem Cell Agency (CIRM) winds down. Will CIRM get a new infusion of billions in state funding via a ballot initiative a la Proposition 71 from more than a decade ago? Will CIRM instead find …Read More

Here are some articles that look especially interesting on stem cells, cancer, and CRISPR. I was just at the SNO meeting in SFO on childhood brain tumors so those are on my mind more. Childhood cerebellar tumours mirror conserved fetal transcriptional programs (Nature) Childhood brain tumors “think” they are building organds in fetuses. H3.3 K27M depletion increases differentiation and extends latency of diffuse intrinsic pontine glioma growth in vivo. (Acta Neuropathologica) from Suzy Baker-led team. H3K27M induces defective chromatin spread of PRC2-mediated repressive H3K27me2/me3 and …Read More

What new papers and news in the stem cell sphere caught your eye? Here are some recent items that seem notable to me. Diabetes relief in mice by glucose-sensing insulin-secreting human α-cells. This paper reports cellular reprogramming to insulin-producing cells in mice. They reprogrammed α-cells with Pdx1 and MafA proteins. ‘Mitophagy inhibits amyloid-β and tau pathology and reverses cognitive deficits in models of Alzheimer’s disease’ in Nature Neuroscience. Using IPS cells for insights. “What open chromatin features predict pluripotency?” asked and answered by the authors of this review …Read More

A new Florida bill (Bill 65 of 2019) could make the practices of stem cell clinics a felony. At the same time it would open the door to patients receiving still experimental stem cells that have at least started the clinical trial process. What’s going on? A number of states have been stepping up action related to stem cells and specifically stem cell clinics. The steps on unproven clinics range from bills, some of which have become law such as here in California and …Read More

Scrolling through a stem cell clinic website can be a surreal experience. Going from the top of the page to the bottom can leave one feeling turned upside down. I wonder what the FTC thinks when they see these sites? Usually at the top of the webpage for many unproven stem cell clinics are big claims, glossy pictures of healthy people, and a lot of buzz. However, often if you then scroll down to the bottom there is some very different fine print with …Read More

California broke new ground with our stem cell law that went into effect on January 1. It requires stem cell clinic firms to post notices informing patients of important information such as the fact that their offerings are non-FDA approved. At this point, 4+ months into the enforcement period, I’m not sure if anyone has looked into compliance. Anyone know? If you run a stem cell clinic, have you posted notices? Is you are a patient in California who has been to such a …Read More
