Cover picture: Triple immunofluorescent staining shows the normal relationship among laminin (green), the myelin sheath (red), and axons (blue) in the mouse peripheral nerve. Selective disruption of laminin in Schwann cells in the peripheral nervous system impairs axonal sorting and myelination, prevents Schwann cell proliferation, and causes apoptosis. For details, see the article by Yu et al. in this issue (pages 4463–4472).
