Scientists report a breakthrough in stem cell production: Stem cells created from ALS patient and used to make neurons. [Via]
Simple switch turns cells embryonic. "Researchers have finally hit the jackpot: Embryo-free embryonic stem-cells!"
Sea Squirt Regrows Entire Body from One Blood Vessel. Most famous as the creature that settles down and eats its own brain (though that is not exactly correct), it appears the humble sea squirt has spectacular regenerative abilities as well, thanks to regeneration niches packed with stem cells. All glory to the sea squirt!
Debating the Moral Status of the Embryo. A favorite scenario of some bioethicists in this debate is often a variation of "if a fertility clinic were on fire and you had only enough time to run in once to effect a rescue, which would you grab—the unconscious clinic worker/or a tank full of hundreds of frozen embryos?" Sometimes the debate degenerates...
The National Academies have finally released suggested guidelines for research with embryonic stem cells and chimeras.
A team of Korean scientists have enabled a woman who has not been able to stand up for the last 19 years due to a spinal cord injury to walk on her own (103 MB .wmv), thanks to a transplant of stem cells from umbilical cord blood. [Via Future Hi.]
Stem cells target cancer tumors. There has been some promising research with embryonic and adult stem cells in the fight against cancer. Meanwhile, California approved $3 billion for stem cell research, good news (debatably) since the 22 stem cell lines available for federally-funded research are contaminated with mouse cells and unusable for treatment in humans, but I wonder if California might end up in a federalism showdown with the new Senate over this. Maybe it will be less of an issue now that researchers have figured out how to derive stem cells from a morula, a four-day old embryo, without destroying it.
Thou shalt not make scientific progress. "Medical research is poised to make a quantum leap that will benefit sufferers from Alzheimer's, Parkinson's, muscular dystrophy, diabetes and other diseases. But George W. Bush's religious convictions stand in its way."
Free stem cells! A Harvard scientist using private money has developed 17 new batches of human embryonic stem cells, which he's offering to any researcher who needs them for the cost of shipping. Perhaps this will help American scientists from losing the edge (unless, as some speculate, Bush is preparing to outlaw it.) Harvard is also developing a multimillion-dollar center to grow and study stem cells.
A case study in modern Washington dishonesty. Michael Kinsley responds to Bush's former chief domestic policy adviser's reply to Kinsley's recent article on Bush's stem cell policy. [Via Fark.]
Scientists in Singapore have grown 'clean' human embryonic stem cells which would pose no threat of infection by animal pathogens if transplanted. Previous ESC lines were mixed with animal cells. Meanwhile in the US, surprisingly little has been accomplished with ESCs in the last year due to the chilling effect of the political controversy. And because of Bush's decision a year ago, any new 'clean' ESC lines could not be be used in federally funded research.
In Canada, the creation of new stem cell lines from discarded embryos is now eligible for federal funding. And in the UK the first licenses to create new stem cell lines have been granted, as has governement approval to pursue therapeutic cloning. The chief executive of the UK's Medical Research Council predicts a "reverse brain drain" of stem cell scientists to the UK. If the US Senate votes to ban all human cloning this spring, even for research purposes, I suspect that America will lose a lot of great minds.
