Cover picture: A cross section through a newborn mouse embryo is shown. The mouse expresses an HB9-GFP transgene (green) specifically in motor neurons. The integrin β1 subunit (red) is strongly expressed in motor neurons, the DRGs, the neuroepithelium in the spinal cord, and the skin. For details, see the article by Schwander et al. in this issue (pages 8181–8191).
