Fig. 8
Photomicrographs of transverse single- and double-labeled sections through mesencephalic and rhombencephalic areas of Protopterus dolloi (P.d), Polypterus senegalus (P.s), and Danio rerio (D.r) showing the location of SATB1/2 or SATB1 (green color) alone or in combination with TH, Otp or 5-HT (red color) immunoreactivity. The markers and the species are indicated in each image. a, b SATB1/2-ir cells in the torus semicircularis and mesencephalic tegmentum (a), and in the central gray (b) of P. dolloi. c Populations of SATB1-ir cells in the central gray and superior reticular nucleus of P. senegalus. d SATB1/2-labeled cells in the central gray of D. rerio. For abbreviations, see list. Scale bars = 200 µm (c), 100 µm (a, b, d, e), 50 µm (f)
