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 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 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

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

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

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

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
Ian Wilmut, Dolly’s dad, says dump hESC? What does this mean? Read More »
Today, an authoritative article was published in the prestigious New England Journal of Medicine (NEJM) that included some of the most comprehensive polling of attitudes in the U.S. and around the world on embryonic stem cell (ESC) research. Their findings indicate very widespread and deep support for ESC research around the globe including in the U.S. and
Many of us have been discouraged by Geron’s decision to end their stem cell program, which included products based on human embryonic stem (ES) cells, but let’s keep some perspective on this and not give up hope. The opponents of hope want us to give up. They who have waged their own self-proclaimed war on
Keep hope: the ‘war’ is not over Read More »
Tomorrow night voters in Mississippi will vote on the so-called “Personhood Amendment”. If passed, the amendment would make a fertilized egg by definition a human being with the same rights as a living, breathing, thinking, walking person in the state of Mississippi. The consequences are not clear, but possibilities include such things as complete bans on
