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

/ / 5 Comments
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 […]

Jose-Silva

What’s the deal with the tension between José Silva and Jacob Hanna over pluripotency? Researchers probing how to reprogram cells into powerful stem cells (induced pluripotent stem cells or IPSCs) and what the molecular mechanisms are behind this process have become entangled in a conflict. Of course over the years scientists including stem cell scientists have

Jacob Hanna on Radically Deterministic Reprogramming @TMM2013

/ / 2 Comments

When Jacob Hanna  says “radically deterministic” cellular reprogramming, what does he mean? Jacob Hanna’s lab recently published a very high profile Nature paper on nearly 100% efficient iPS cell formation based on targeting a factor called Mbd3. This super efficiency is a major departure from past reported efficiencies. This morning here at the Till &

100% reprogramming efficiency reports Jacob Hanna

/ / 6 Comments

A team at the Weizmann Institute of Science in Israel led by Jacob Hanna reports today near perfect reprogramming efficiency to make induced pluripotent stem cells (iPSCs) by eliminating a single factor called Mbd3 from the cellular equation. On first glance, the Nature article (Rais, et al.) seems to be all about boosting cellular reprogramming efficiency to close

Jaenisch-Hanna

Professor Rudolf Jaenisch of MIT and his former postdoc/now assistant professor at The Weizmann Jacob Hanna have gotten into a very public, stem cell skirmish over conflicting papers. Hanna raised concerns over a Jaenisch lab paper and things have escalated from there. This mess is playing out before our eyes on PubMed (there was a comment from Hanna

Weekly reads: hit pause on human life, CIRM pause, 23andMe data, blast from the past

/ / 20 Comments

Remember cryonics, the idea that you could hit pause on human life? This relies on the super-cold power of liquid nitrogen or some other ultra-freezing method. Apparently cryonics is still a thing and there are people with even just their heads frozen. A new story claims a different way to hit the pause button on

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

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
