Great news as Sherley v Sebelius officially over: Supreme Court Takes a pass!

Today the Supreme Court agreed to review three cases, none of which were Sherley v Sebelius. What a great day! For those curious, Certiorari Granted (subheading on Supreme Court announcement) means the Court has granted review of these cases. This is wonderful news for patients, the stem cell field, and probably biotech Advanced Cell Technology …

Advanced Cell Technology (ACTC) announces plan to make iPS cell-derived platelets: some thoughts

Advanced Cell Technology (ACT) is well into clinical trials for macular degeneration (the leading cause of blindness) using human embryonic stem cell (hESC)-based retinal pigmented epithelial cells (RPE). To date, the trials suggest the products are safe. Efficacy? We don’t know. I am cautiously hopeful, but it is frustrating to know that most clinical trials …

Great letter on Guv Perry’s California visit video from the artist

On Monday, I made a big stink about Texas GOP Governor Rick Perry visiting a lab (that of Jeanne Loring) at Scripps Research Institute here in California because the lab in question is a leading group doing human embryonic stem cell (HESC) and Perry is a strong opponent of such research. I thought the visit …

Why aren’t there vertebrate super pygmies?

Why aren’t there are super pygmy vertebrates? For most vertebrate animals, their early embryonic development unfolds in extremely congruent fashions. Embryo growth is stem cell-dependent and in large part, despite different gestational periods, the molecular and cellular machinery that controls vertebrate development is almost perfectly conserved. Yet at maturity vertebrates end up with a range …

Why is the human brain super-sized?

human-brain

Why do people have such a big brain compared to other animals? Vertebrate embryonic development is a highly conserved process, particularly in the earliest phases. (note: you may find this September 2020 post on regulation of bee brain size to be interesting.) A wide variety of vertebrate animals including humans start out with embryonic body plans …

Witherspoon word cloud is surprisingly revealing

Remember that Witherspoon report on stem cells earlier this week that was supposed to be an authoritative look at embryonic stem cell research in its 100+ pages? I posted my own thoughts on it here including some criticisms but also some surprising areas of agreement between this blog and them, even though they cited this …

Secrets of the Witherspoon Gang

What’s the Witherspoon Institute? Most of you know about the 2 scientists who for their own reasons want to kill embryonic stem cell (ESC) research and with it the hopes for millions of people. Relatively new on most of our radar screens, however, is an extremist right-wing “think tank” called The Witherspoon Institute, which I …

Word Cloud of Every CIRM-funded grant yields some surprising insights

CIRM, the California stem cell agency, has funded hundreds of grants during its relatively short existence. You can do searches of these grants through a handy dandy web portal that CIRM has made available–it’s a very cool tool and I commend CIRM for making it available. I wish the tool had more options however including …

Ian Wilmut, Dolly’s dad, says dump hESC? What does this mean?

Ian-Wilmut

Sometimes a top scientist makes news with a quote on research and that happened with Ian Wilmut recently on stem cells. Move away from research on human ES cells (hESC) in favor of very new and still largely unclear trans-differentiation technology? I say, no way. But, Bradley Fikes of the North County Times has reported …
