Figure 2


Fig. 2. deltaB and deltaD are expressed specifically in projection neurons. (A-C) Dorsal view of epiphysis, showing expression of deltaA, deltaB and deltaD in wild-type embryos at 18 hours. (D-F') Confocal section of the epiphysis, showing expression of deltaA, deltaB and deltaD (red) in Tg(HuC:GFP) embryos at 24 hours. (G-I') Confocal section of the epiphysis, showing expression of deltaA, deltaB and deltaD (red) in Tg(AANAT2:GFP) embryos at 24 hours. Anterior is upwards. Scale bars: 20 µm. White arrowheads indicate double-labeled cells.
