(p 196) use near-field scanning optical microscropy (NSOM) to visualize nanoscale β-adrenergic receptor clusters in the membranes of murine cardiac myocytes (see also News & Views by Park & Palczewski, p 184). The cover shows fluorescence and NSOM images of neonatal mouse cardiac myocytes stained for the β2-adrenergic receptor (red) and the nuclei (blue).
