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 fibres (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 fibre.
(C): Equator of the lens (3), stain Haematoxylin-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 fibres.
Background: At the equator the lens epithelial cells differentiate into recognisable nucleated lens fibres (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
