Why is CRISPR Cas9 gene editing such a big deal? Imagine being able to make mutations in any gene you wanted say in stem cells in a relatively simple, quick and affordable fashion? Sounds exciting, huh? Every so often a new kind of technology comes along in the biomedical sciences that is a true game […]

I have a soft spot for fibroblasts, perhaps because one of the first immortalized cell lines I ever grew was NIH3T3. These are mouse fibroblasts that have been immortalized. They are very useful for a variety of experiments. I used them to study an oncogene called E2A-PBX1. Experience with fibroblasts including 3T3s I was amazed

The FDA has been busy with the COVID pandemic but it has many other things on its plate as well including cell therapies. Today I’m sharing some recent agency news and brief perspectives on it. FDA focus on clinic-related umbilical cord cell drug makers The agency warned an Idaho company that produces and sells umbilical

The paper of the week reports using base-editing, a kind of gene-editing, to reverse mutations associated with rapid aging syndromes, generally called progeria, but there are a lot of other interesting pubs to recommend for reading this week. I go over it all in this post. Gene-editing to fight premature aging syndromes In vivo base

As a pivotal advance in the gene-editing field and timeline, CRISPR continues to be utilized for research on stem cells and human diseases. Today, I will explain some of the most notable recent findings in the stem cell-CRISPR field. To start things off, I have also created an infographic that briefly explains what CRISPR-Cas9 is,

New research on stem cell patches is exciting. However, more broadly, “stem cell patches” can mean very different things. What I’m talking about here are the types of patches that can repair holes or other problems with tissues. This is a powerful regenerative approach. In contrast, I’m not a fan of the type of stem cell

Could there be stem cell doping or gene doping at the ongoing Paris Olympics right now? I’ve wondered about such things happening throughout several past Olympics. In fact, I asked this kind of question 12 years ago. Authorities are taking such possibilities even more seriously. What would stem cell doping mean? How could cells or

Gene editing continues to advance both in the clinic trial arena and at more basic science levels including a report on a new approach called click editing. The two gene editing papers below highlight the variety of tools now available. Gene Editing papers including click editing Click editing enables programmable genome writing using DNA polymerases

I’ve only met one scientist who was openly a Trump fan, but I’m sure there are more out there. Still, it seems most scientists are no fans of the former president. A new WaPo piece highlights how federal scientists are worrying about a possible second term for the former president. Government scientists & a second

Some recent claims had me wondering whether Liz Parrish is the world’s most genetically modified person. She and her firm BioViva are making that claim. It’s an important question but maybe not for the reason many of us first might think. This is not really about one person. Instead, this is a weighty question because
