Morphology of Radial Astrocytes Projecting to L-MO (A) Maximum intensity projection (MIP) along the medial-lateral axis of a 20 μm section from Tg(elavl3:H2B-GCaMP6f);Tg(gfap:tdTomato) fish. Dashed line, L-MO location. Neurons, magenta; glia, green. (B) MIP along dorsal-ventral axis of a 20 μm section, same fish as (A). Radial astrocytes ramify in L-MO. (C) MIP along the rostral-caudal axis of a 20 μm section in hindbrain. Radial astrocyte processes project ventral-laterally. Scale bar is corrected for 4× expansion (Freifeld et al., 2017, Tillberg et al., 2016) to approximate in vivo dimensions. Arrowhead indicates microscopy software stitching artifact. (D) MIP along dorsal-ventral axis. Diagonal section with one (right) or several (left) radial astrocytes electroporated with synthetic dye. Astrocytic somata are proximal to dorsal midline of hindbrain; their processes run ventral-laterally, are dense in lateral hindbrain (green at brain border), and appose GABAergic somata (left: white arrow, magenta, labeled by Tg(gad1b:RFP)); radial astrocytes (right: gray) labeled by Tg(gfap:jRGECO1b). |
