Fig. 5

talin1 is required for CFC in zebrafish. (A) talin1 is expressed within the POM and retinal/RPE cells lining the CF at 33 hpf (arrow). (B,C) Lateral views of the eye of tln1^hi3093Tg mutant (C) and wild-type sibling (B) at 3dpf. tln1 mutants possess colobomas. (d-F) Distal section through the eye of a 32 hpf embryo demonstrating talin1 expression within the retina/RPE cells lining the CF (arrows) and the hyaloid vasculature (marked by GFP expression from fli1a:eGFP; arrowhead). (G-J) Sagittal sections through the eyes of 48 hpf tln1 mutants and siblings stained with Lam-111 (red) and Sytox-green (DNA; green). BM degradation is disrupted in tln1 mutants at 48 hpf. (K-N) Maximum projection images of the distal hyaloid in tln1 mutants and siblings demonstrating severe hypotrophy of the hyaloid in the tln1 mutant at 44.5 hpf. Scale bar=20 µm (G-J, K,M) and 50 µm (L,N).
