Each year I metaphorically try to look into a crystal ball for stem cell predictions for the coming year and I did so for 2020, but the COVID-19 pandemic threw a monkey wrench into my predictions. It actually kind of blew some up. It also raised some interesting questions and dilemmas. For instance, do many […]

Three new studies reported in preprints all show severe DNA damage to human embryos from CRISPR a surprisingly high percentage of the time including in some cases loss of heterozygosity (LOH). Anywhere from about a quarter to half of CRISPR’d embryos exhibited major genome damage. As readers of The Niche know, I never was a

Two prominent scientists, Robin Lovell-Badge and George Daley, have been amongst the most outspoken proponents of leaving the door open to heritable human genetic modification via CRISPR. While they each have articulated their reasons in somewhat different ways at times, their core reasons arguing in favor of future heritable CRISPR appear largely the same. In

Reports are out that a scientist in China has been working to make a CRISPR baby for some time and supposedly has made twin genetically modified babies. I see this work as unethical and dangerous. Just a couple years ago when I published my book GMO Sapiens on potential use of CRISPR in a heritable manner
Why CRISPR baby production (if it happened) was unethical & dangerous Read More »
Should we be using the term ‘genetically modified human’ in discussions of heritable use of CRISPR in people? During the still ongoing discussions of genetic modification in the human germline and potentially in actual human beings in the future, an interesting, but difficult question has emerged: What words or names would be most appropriate for
Is ‘genetically modified human’ a loaded name? Read More »
Toward the end of each year I make predictions for the stem cell and regenerative medicine field for the coming year. I’ve been doing this for more than a dozen years in various forms. In this post I’m looking at the (gene-edited, stemness enriched) tea leaves for 2025 for the regenerative arena. These predictions include

It’s been almost seventeen years that I’ve been a professor here at UC Davis Medical School. It feels like home. I enjoy teaching our first-year medical students each year. Some end up doing research in my lab. Our school recently got a nice write-up over at STAT News by Usha Lee McFarling on the diversity

Stem cell biologist Jacob Hanna has a new startup called Renewal Bio. Its goal is to harvest cells or tissues from human embryo or fetus models for clinical use. I believe that their commercial ambitions have so far outstripped careful thought and discussion in the broader community of researchers. There are major risks here for

Another busy week including on the grant writing treadmill or should I say Mobius strip, but I’m always on the lookout for new reading and this week a lot popped up on regeneration. Also, a paper on healing and scarring. I regularly write about stem cell journals. For a long time, it seems like Cell Stem

The last few years in the stem cell and regenerative medicine arena have been complicated in many ways. Variables like surging stem cell clinics and COVID have made predictions harder. Even so, trying to make predictions is useful and it’s fun to go over past year’s predictions. You can see my scorecard on my 2021
