Functional Neurons Induced From Adult Stem Cells. Meanwhile, stem cells may be better than bone marrow for certain cancers, and have the potential to revolutionize the supply of blood. Anecdotal success stories continue to pile up.

retrovirally transforming pancreatic cells from adult mice into insulin-producing beta cells

Scientists Repurpose Adult Cells - "Scientists have transformed one type of fully developed adult cell directly into another inside a living animal, a startling advance that could lead to cures for a variety of illnesses and sidestep the political and ethical quagmires associated with embryonic stem cell research."

28 Days Later...more stem cells!

Scientists have discovered that "endometrial regenerative cells" (ERC's) -- in other words, human menstrual blood -- contains stem cells. ERC-derived stem cells seem to have a number of superior traits to both bone marrow derived and umbilical cord derived stem cells, the previous gold standards: they can give rise to a variety of different cell lines without differentiation, they multiply more quickly than other stem cells, they are able to replicate more times without adversely mutating, and they apparently do not need to be closely genetically matched to the recipient. Now some women have even begun banking their menstrual blood to preserve their stem cells through a company called "C'Elle: Your Monthly Miracle" -- check out their FAQ and online video. This follows last May's announcement that menstrual blood derived cells can pretty much cure Duchenne Muscular Dystrophy in mice, a disease for which there is no current therapeutic treatment available.

Adult skin stem cells heal spinal injuries

Canadian scientists heal spinal injuries with stem cells from skin (in rats). "Over the course of their research, the team found that skin-derived stem cells share characteristics with embryonic neural stem cells, which generate the nervous system. ... After 12 weeks, the rats were able to walk better, with more co-ordination." Previously on the Blue: Making adult stem cells embryonic, regenerating liver tissue with adult bone marrow stem cells

Examining Bush's stem cell policy, two years later.

Examining Bush's stem cell policy, two years later. Kinsley: Put it all together, and the stem cells that can squeeze through Bush's loopholes are far less promising than they seemed two years ago, while the general promise of embryonic stem cells burns brighter than ever. If you claim to have made an anguished moral decision, and the factual basis for that decision turns out to be faulty, you ought to reconsider or your claim to moral anguish looks phony. But Bush's moral anguish was suspect from the beginning, because the policy it produced makes no sense.
