Fig. 2. Photomicrographs of transverse sections through the developing Xenopus forebrain illustrating the x-Shh expression in embryonic stages (st38–41). No expression is detected in most rostral portion of the telencephalon (a), although a weak expression starts in the subpallial POC (b), which is continuous caudally in the forebrain within the ventricular zone (b–i). At thalamic levels, x-Shh expression is restricted to the Zli in the P2–P3 boundary (b–g). Of note, x-Shh positive cells were present in the anterior tuberal region (f–h) whereas they were not detected at posterior tuberal levels (see asterisk in g–i). The schematic drawings of sagittal sections illustrate the levels of the sections a–i, the extent of the x-Shh expression and the topographic organization of the implicated areas. Scale bars = 100 μm. Image published in: Domínguez L et al. (2010) Copyright © 2010. Image reproduced with permission of the Publisher, Elsevier B. V. Larger Image Printer Friendly View
