While people in California can think they are in the centre of the (embryonic) stem cell universe due to Proposition 71’s $3 Billion and the invasion of good scientists into the West Coast, Massachusetts academic and biotech people also are thinking along those lines, so state officials quickly set up a $1.25 Billion package for… Continue reading Stem Cell Cup: California Embryonics vs Massachusetts Oldies: $3 vs $1.25 Billion
If you have previously thought (in your spare time) that the conventional wisdom concerning blood formation is that the yolk sac’s embryonic blood-forming cells serve only the embryo, while the source of adult blood-forming stem cells is the region called aorta-gonad-mesonephros (AGM), it’s time to think it again due the elegant experiments of Samokhalov et… Continue reading 2 models of embryonic and adult blood formation: Figure by Ueno and Weissman

Short peer-review storytelling : One big technical problem of human embryonic stem cells (hESCs) (in contrast to mouse embryonic stem cells) that hESCs normally undergo high rates of spontaneous apoptosis and differentiation, making them difficult to maintain in culture. Now we are getting to know a bit more on the molecular background of these processes.… Continue reading Stories from my PubMed feeds: hESCs, p53, apoptosis and differentiation
If there is any? Stem cell biology and regenerative medicine as an institutionally specified discipline is quite young, about a decade old. Bone marrow transplantation traces its roots back to the 1970-s, but many people don’t realize that it is the most useful although restricted form of stem cell therapy till this day. In my… Continue reading What is the birth date of present day stem cell biology?

“Allowing research into the medical uses of adult stem cells, but not embryonic stem cells, is the equivalent of sending astronauts to work on the international space station with a single tool” according to Dr. Geoffrey Lomax, senior officer for medical and ethical standards of the California Institute for Regenerative Medicine, running California’s $3 billion… Continue reading Adult stem cells and astronauts in the ISS with one screwdriver
Finally a journalist at Wired, Brandon Keim thought it’s time to check out some facts and formulate real arguments in the embryonic stem cell funding debate instead of boondoggling. He has collected good historical examples of long-term funding in drug research, which then saved many lives, like Taxol, and has enumerated fields of promising science,… Continue reading Real arguments not just echo chambering in embryonic stem cell funding debate
