Title: Equatorial region of the eye lens
Description:
(A): Capsule of the lens, immunoperoxidase staining with DAB and monoclonal anti-collagen IV-antibody , 1d postnatal rat.
Equator with nuclei of lens cells (frozen section). Collagen type IV and glycosaminoglycans are present in the thick basement
membrane (1) of the lens i.e. lens capsule. Furthermore the zonular fibers (2) also appear positive for collagen type IV.
(B):Tangential section through the lens, stain Azan, monkey. The presence of collagen is confirmed in the lens capsule (blue).
(2) Zonular fiber.
(C): Equator of the lens (3), stain hematoxylin-eosin, pig. Like in (B) a basement membrane (1) surrounds the whole lens, it is hardly
visible in routinely stained sections. At (2) thin zonular fibers.
Background: At the equator the lens epithelial cells differentiate into recognizable nucleated lens fibers (see B, C).
Nuclei are found at considerable depth in the cortex of young lenses.
Keywords/Mesh: eye, lens, capsule, collagen IV, histology, POJA collection
