Fig. 3 Radial glial cells strongly express Pgr.
A to O: Pgr immunohistochemistry (red) on tg(cyp19a1b-GFP) transgenic fish showing the strong expression of Pgr in cyp19a1b-GFP positive radial glial cells (green). The cyp19a1b-GFP radial glial cells (green) that line the ventricular surface exhibit a stronger Pgr staining, notably in the subpallial (A to F) and pallial regions (G to I). This is also true in more posterior regions such as the posterior tuberculum (J to K) or around the posterior recess (NPR) of the caudal hypothalamus (M to O). Vv: ventral nucleus of the ventral telencephalic area; Vd: dorsal nucleus of the ventral telencephalic area; Dm: medial zone of the dorsal telencephalic area; TPp: periventricular nucleus of the posterior tuberculum; NPR: nucleus of the posterior recess of the hypothalamus Scale bars: 30 μm (D, E and F); 75 μm (J, K and L); 150 μm (A, B, C, G, H, I, M, N and O).
