Summary:
Low levels of toxic substances cause critical stem cells in the central nervous system to prematurely shut down. That is the conclusion of a study published today in the on-line journal PLoS Biology. This research, which is the first to identify a common molecular trigger for the effects of toxicant exposure, may give scientists new insights into damage caused by toxicant exposure and new methods of evaluating the safety of chemicals.
