ny cell therapy risks introducing mutated and possibly tumorigenic cells. Now results from Peter Stambrook (University of Cincinnati, Cincinnati, OH) and colleagues underline this concern for embryonic stem (ES) cells, which are one possible source for therapeutic cells. Stambrook constructed a cell line in which he could detect loss or mutation of a heterozygous marker gene. Loss (rather than ...

n page 803, Gourlay et al. report the first evidence that the actin cytoskeleton can affect release of reactive oxygen species (ROS) by mitochondria, and thus life span in yeast. Certain mutant Saccharo-myces cerevisiae strains with alleles that reduce actin dynamics possess defective mitochondria. The team O Cells with increased actin dynamics live longer. went on to show that such strains dis...
