CAR-T for Lupus

Can researchers use CAR-T for lupus? It’s always exciting when one’s home institution has an interesting new therapy in development.  Here at UC Davis Health, there has been an increasing stream of such encouraging trials in the pipeline. I’ve written before about the promising trial of stem cells for spina bifida. Now there’s news related […]

2023 stem cell predictions grades reflect wild year for regenerative medicine

stem cell predictions

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

dr. jeffrey weiss, MD Stem Cells

There is still plenty of reason to worry about unproven stem cells being marketed in the U.S. and elsewhere around the world. I’ll start with a new item here in the U.S. on a firm called MD Stem Cells and end with a newly published paper about how things are going in Poland on this

Weekly reads: stembryos or human embryo models, new Macchiarini sentence

stembryos, embryo models Monash

Researchers have been making stem cell-based embryo models for years now and a few folks have taken to calling these “stembryos.” Other names like gastruloids and blastoids are sometimes used too. “Embryo models” might be the simplest and best name. The embryo model research has advanced relatively quickly from very basic, not very organized structures

‘We don’t want to freak people out’: about that Jacob Hanna human embryo model startup

Jacob Hanna Renewal Bio

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

humans with tails

A piece on human tails and how we lost them caught my eye so I’ll start my weekly reads with that. This week I had the fewest Zoom meetings in ages, which allowed me to get more work done in my own lab and more reading. How about that? I even had some in-person meetings

human-embryo-modification

Although in my years as a stem cell biologist I haven’t yet been in a leadership role at the International Society for Stem Cell Research or ISSCR, unproven stem cell clinics have claimed that I somehow speak for ISSCR. I am just a standard member of the group like thousands of other researchers. In fact,

When does a human embryo model become the real thing & other tough questions for a new field

human embryo model mukul tewary sm

A human embryo model is a laboratory-produced collection of living cells that has some key things in common with real human embryos. They are made from pluripotent stem cells, which include embryonic stem cells and induced pluripotent stem cells or iPS cells. This research is both exciting and ethically complicated, raising some difficult questions. Embryo

Synthetic embryo or embryo model tech reported in Science: how big is this?

progression-for-cgs_bs-1-e1488559282646

Can you make a synthetic embryo, also called an embryo model? Developmental biologist Magdalena Zernicka-Goetz has long been on the trail of this seemingly almost uncatchable quarry. With her team’s publication in Science today they took a big step forward on this path even if some major hurdles remain. You can see her discussion of
