Secretagogin expression in the mouse brain stem. a–a₁’’ EGFP-expressing neurons in secretagogin–EGFP mice showed secretagogin immunoreactivity as exemplified in the microcellular tegmental nucleus (white arrowheads in a–a₁’’). Occasionally, EGFP-expressing neurons remained secretagogin immunonegative (black arrowhead in a–a₁’’). b–f₁ Secretagogin⁺ neurons in the solitary tract nucleus (b, b₁), dorsal nucleus of vagus (c, c₁), microcellular tegmental nucleus (d, d₁), locus coeruleus (e) and the superior colliculus (f, f₁). LC locus coeruleus, MiTg microcellular tegmental nucleus. Scale bars 1 mm (b–f), 100 µm (a’’, d₁, f₁), 70 µm (b₁), 40 µm (c₁)
