Fig. 1. Expression of VEGF and FLK1 during chicken retinogenesis. (A-F) Images of E5 and E6 retinal sections show double immunostaining against VEGF (A,D), Islet1/2 (B,E) and the respective merged images (C,F). (G-I) Images of E6 sections show in situ hybridization for FLK1 (G), and immunostaining for PCNA (H) and BrdU (I, in ovo labeling for 3 hours). Scale bars: 50 µm. gcl, ganglion cell layer; vz, ventricular zone.
