Article Title: The choroid-sclera interface: An ultrastructural study

doi: 10.1016/j.heliyon.2022.e09408

Figure Lengend Snippet: Chicken, 14 weeks old. A: Semithin section of the chicken sclera-choroid complex, overview: The sclera with its inner cartilaginous part and outer fibrous part and the adjacent choroid is clearly discernible, with the choroid-sclera transition zone intact. L depicts lymphatic lacunae, BV: blood vessels (containing avian nucleated erythrocytes), RPE: retinal pigment epithelium. Boxed area marks the localization of the further investigated sclera-choroid transition zone (valid for all species). B: Thin and long processes of fibroblasts form the sclera-choroid transition zone (arrowheads), connected with membrane specializations representing tight junctions (arrows). Scleral collagen fibrils (asterisks) undercut the fibroblast lamellae, reaching also into deeper layers that contain non-vascular smooth muscle cells (SMC; as identified by their intracellular striated pattern of actin-filaments). C, D: When closely investigating the fibroblast front-line lamella facing the sclera (asterisk in C, D), fibroblast (F) club-like membrane protrusions into the scleral matrix were detected (white arrowheads in C, D) as well as in the undercutting scleral collagen fibrils (black arrowheads in C, D), that were reminiscent of hook-and-loop like fasteners (with protrusions representing the hook, and the collagen matrix the loop). Fibroblasts itself were attached via tight junctions (open arrowhead). Micrograph D represents a magnification of boxed area in C. A putative difference in size of collagen fibres in chicken as seen in 1 B- to D has been interpreted as optical effect due to fibre orientation.
