About the Cover
Cover: Cardiac neural crest cells derived from the connexin 43 knockout mouse exhibit altered cell motility associated with a fundamental change in their actin cytoskeleton. Phalloidin staining (red) shows actin stress fibers in connexin 43 deficient crest cells organized in a polygonal network, rather than in parallel stress fiber bundle arrays as seen in wild-type cardiac crest cells. Nuclei are stained with DAPI (blue). See research article by Xu et al. on p. 3629.
