Loss of tcf7l1a modifies the gdf6aU768/U768mutant eye phenotype.
(A–H) Lateral views of eyes in wildtype (A, E), Ztcf7l1a-/- (B, F), gdf6aU768/U768 (C, G) and double gdf6aU768/U768/Ztcf7l1a-/- (D, H) embryos at 36hpf (A–D) and 52hpf (E–H). Dorsal up, anterior to left. Arrows indicate the lens. Scale bar = 200 µm. (I) Whole mount fluorescent in situ hybridisation for rx3 and pax2a in wildtype (I), Ztcf7l1a-/- (J), gdf6aU768/U768(K) and double gdf6aU768/U768/Ztcf7l1a-/- (L) embryos at 10hpf. Dorsal view, anterior up. Arrows point to rx3eye field expression. Scale bar = 100 µm. (M) Eye volume quantification in wildtype (n = 7), Ztcf7l1a-/- (n = 6), gdf6a-/-(n = 6) and gdf6aU768/U768/Ztcf7l1a-/- double mutant siblings (n = 3) at 36hpf (data in Supplementary file 1R). Single experiment, unpaired t-test. (N) Eye field volume quantification from rx3 fluorescent in situ hybridisation shown in I-L in wildtype (n = 7), Ztcf7l1a-/- (n = 4), gdf6a-/-(n = 8) and gdf6aU768/U768/Ztcf7l1a-/- double mutant siblings (n = 4) at 10hpf (data in Supplementary file 1S). Single experiment, unpaired t-test.
