CRISPR gene editing has made rapid progress heading from bench to bedside. Perhaps the fastest has been its progress toward clinical use to combat sickle cell disease. We’ll start with a new paper on one major effort here. CRISPR gene editing. This process often involves cutting DNA, which then can be used as an opening to …

It wasn’t that long ago that Chinese scientist He Jiankui got out of jail. Why was he in there? For doing unauthorized human CRISPR to make heritably gene-edited humans. He botched that and apparently forged some approvals to make it happen. The three children involved may have life-long health problems as a result. I wrote …
Totipotency literally means all powerful, but it refers in biology to specific cells. These cells can make every type of cell in the body of an organism plus the extraembryonic tissues needed for development. This includes humans. So if you could reprogram human cells like blood or skin cells into totipotent stem cells, you might …

Earlier this year Chinese researcher He Jiankui finished his prison sentence. When I saw that news I wondered about the next chapter for him. It seems he’s already back in the lab doing genetics research. At least that’s according to a blog by He Jiankui himself. Can we trust that what he has written on his website is …

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 …

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 …

Some people consider the brain to be equivalent to a living computer and in that sense it’s too bad that computers don’t have the equal of neural stem cells to help them fix themselves. Is the internet one big neural network-like web? There was a quake in the stem cell internet as CIRM’s main website …

We often don’t think of them that way but reproductive cells like sperm and egg are also relatives of stem cells, and it turns out that there are stem cells that make the reproductive cells too like sperm stem cells. Sperm and germ cell stem cells DNMT3A-dependent DNA methylation is required for spermatogonial stem cells …

The big news of the week was a $3.6 million settlement by a stem cell clinic, StemGenex, and one of its doctors in a class-action suit. I covered this StemGenex settlement and so did Michael Hiltzik of the LA Times and Paul Schloesser at Endpoints. I’d say this was good news for the stem cell field …

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 …
