Fig. 5 miR-7 Demarcates Specific Groups of Cells in the Medial Forebrain of Platynereis and Zebrafish. Expression of miR-7 in relation to the axonal scaffold (green) in (A–C) Platynereis and (D–G) zebrafish. (A–C) Apical views, ventral to the bottom. White arrows: position of large multiciliated crescent cell as landmark for orientation; yellow arrowheads: microtubule-rich dendrite; asterisks: position of neurosecretory forebrain plexus. (D, F, and G) Lateral views, anterior to the left, (E) ventral view, anterior: top. Yellow and white circles outlines the same groups of cells in Figures 3M, 4J, and 5E–5G. AC, anterior commissure; POC/OC, postoptic commissure/optic chiasm.
