Lens fibers of the eye

Title: Lens fibers of the eye
Description:
(A): Lens, stain Azan, monkey. (1) Lens capsule consisting of collagen IV and glucosaminoglycans. (2) One layer of the anterior
lens epithelium. (3) Note that the lens fibers (elongated lens cells) have lost their nuclei.
(B, C): Lens, stain hematoxylin-eosin, pig (B). Electron micrograph, bovine (C).
Details of the hexagonal lens fibers (anterior cortex). Note ultrasturcturally the uniform aspect of the granular cytoplasm,
adjacent cells are separated by a thin intercellular space (about 15 nm width).
Background: Lens fibers filled with several types of proteins e.g. filensin (IF filament protein that contains attachment sites
for crystallins) and lens-specific proteins the α-, β-, γ-crystallins.
Both proteins maintain the conformation and transparency of the lens fiber cells.
Keywords/Mesh: eye, lens, lens fiber, histology, electron microscopy, POJA collection
