Often when we dig a little into the science of stem cells, people get turned off by all the strange names of molecules and jargon. However, whether you are a scientist, patient, investor, reporter, etc. there are some aspects of stem cell science that are ‘musts’ to know about. For example, you need to know […]

Yamanaka may have found a way to give exogenous Myc the boot from the iPS cell universe. It has always been a frustration in the iPS cell field that Myc, a proto-oncogene, is so important for reprogramming. Yes, you can make iPS cells (especially mouse) without Myc, but it can be orders of magnitude harder,
New iPS cell method: drop Myc or not yet? Read More »
A paper just came out in PNAS entitled “Promotion of direct reprogramming by transformation-deficient Myc“. The main thrust of this paper is that the tumorigenic and pluripotency-related functions of Myc could be separated. It focused primarily on the lesser studied LMyc. The topic of the intertwined good (pluripotency) and bad (tumorigenicity) functions of Myc, addressed
Tumorigenicity and Pluripotency teased apart? Not yet for Myc Read More »
Stem cell hype is a big problem these days. It’s been going on for decades. Even some generally good citizens of the stem cell and regenerative medicine arena engage in it at times. Maybe a few of them don’t even realize what they are doing. I think a few journalists occasionally fall into the hype

We’ve known that most organs have resident stem cell populations for decades, but things have been less clear in the lung and it has only been relatively recently that lung stem cells have been definitively characterized. Why is so important? Lung stem cells, whether endogenous or made in the lab, have the potential to help

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

A few dozen clinics in the US sell an unproven RNA therapy called supportive oligonucleotide therapy or SOT. The product comes from a Greek firm RGCC or Research Genetic Cancer Center, which also pre-tests patients’ gene expression to design the RNA product. Clinics marketing SOT in the US say it is intended to act by
Every year I make stem cell and regenerative medicine predictions. Looking at my predictions for 2023, they reflect a wild year but in many ways a good one overall. Below I have graded my 2023 predictions. Overall, my crystal ball gave solid results. Some of the predictions have been condensed to keep things concise, but you

The big news broke Friday that the FDA approved two new gene therapies for sickle cell disease. While the approvals were expected and the actual use of these treatments will be complex on several levels, this is a historic development. 2 FDA-approved gene therapies for sickle cell Friday’s news follows on recent UK approval for
Can you paradoxically kill yourself early by trying to cheat Death? For example, die through risky anti-aging approaches? The question came to mind because such longevity efforts have become more extreme. They also get more hype in the media. I’ve been following the anti-aging space mainly because many interventions involve risky stem cell injections. Those
