...matched set of articles published online by the British science journal Nature last week seemed calculated to provide succor to both sides in the simmering stem-cell debate. In one study, University of Minnesota researchers isolated bone-marrow cells from adult mice, grew them in dishes and injected them into mouse embryos, where they developed into nerve, liver and other types of cells. In the other study, scientists from the National Institutes of Health did similar work with stem cells from mouse embryos, which developed into brain cells that produce dopamine and could be used to treat Parkinson's disease...
...have not had an invasion of mice,” Ware said...
...okay with the animals. Consider, for instance, the experience of San Francisco Chronicle Editor (and Mr. Sharon Stone) Phil Bronstein, who entered the cage of a 10-foot Komodo dragon and had his foot promptly and severely chomped when said animal mistook his toes for delicious white mice...
Meanwhile, research teams are scrambling to create animal models for autism in the form of mutant mice. They are beginning to examine environmental factors that might contribute to the development of autism and using advanced brain-imaging technology to probe the deep interior of autistic minds. In the process, scientists are gaining rich new insights into this baffling spectrum of disorders and are beginning to float intriguing new hypotheses about why people affected by it develop minds that are strangely different from our own and yet, in some important respects, hauntingly similar...
...colleagues are exploring how certain teratogens (substances that cause birth defects) could lead to autism. They are focusing on the teratogens' impact on a gene called hoxa1, which is supposed to flick on very briefly in the first trimester of pregnancy and remain silent ever after. Embryonic mice in which the rodent equivalent of this gene has been knocked out go on to develop brainstems that are missing an entire layer of cells...
