Fig. 1. Transgenic analysis of Emx2 regulation in the forebrain. The diagram depicts a restriction map upstream of the Emx2-coding region (the translational start (ATG) is indicated). The restriction fragments, which are cloned into a vector containing lacZ and a minimal promoter are represented by bars. For each construct, the numbers of transgenic embryos that showed ß-galactosidase staining in the telencephalon (tel) or diencephalon (dien) and the total number of transgenic embryos (tg) are indicated. B, BamHI; E, EcoRI; G, BglII; H, HindIII; N, NdeI; Ns, NsiI; S, SacII; X, XhoI.
