Fig. 1 Expression of pgr transcripts in the forebrain of adult zebrafish.
A, B, C and D: pgr transcripts detection with antisense probes in the telencephalon (A), the preoptic area (B), in the ventromedial hypothalamus (C) and the nucleus recessus posterioris (D). E, F, G and H: In situ hybridization with antisense probes (E and G) and sense probes (F and H) on parallel sections. The sense probe does not generate any signal. ATN: anterior tuberal nucleus; CP: central posterior thalamic nucleus; DIL: diffuse nucleus of the inferior lobe; Dl: Lateral zone of the dorsal telencephalic area; Dm: medial zone of the dorsal telencephalic area; Hv: ventral zone of the periventricular hypothalamus; LH: lateral hypothalamic nucleus; LR: Lateral recess; PTN: posterior tuberal nucleus; Vv: ventral nucleus of the ventral telencephalic area; Vd: dorsal nucleus of the ventral telencephalic area; PGZ: periventricular gray zone of the optic tectum; PPv: periventricular pretectal nucleus; TeO: Optic tectum; TL: torus longitudinalis; TSc: torus semicircularis; VCe: valvula cerebella. Scale bars: 50 μm (G and H); 100 μm (E and F); 200 μm (A and B); 400 μm (C and D).
