On the cover: A confocal microscopy image of an adult mouse cardiac myocyte expressing α1A-green fluorescent protein (GFP; green) and stained for caveolin-3 (red) is presented as a blended image. Removing part of the caveolin-3 signal at the membrane to reveal the nuclei expressing α1A-GFP inside the cell further enhanced the image. See related article, page 992.
