A new eye lens structure associated with capsule/basement membrane growth
Wouterus TM Gruijters
TL;DR
A new structure in the eye lens capsule, possibly linked to basement membrane growth, was discovered in sheep and mice.
Contribution
The discovery of a periodic striped structure in the lens capsule associated with basement membrane growth.
Findings
Periodic stripes were found on the inner surface of the sheep lens capsule.
Cell feet and vesicles were observed inserting periodically into the capsule in ultra-thin sections.
A similar structure was confirmed in cryosections of mouse eyes.
Abstract
Eye lens capsules contained a previously overlooked structure possibly derived from the Zonule of Zinn or lens epithelium. Sheep lens capsule inner surface revealed periodic stripes spaced at about 8µm over an area of more than 200µm long and wide. Ultra thin sections of a similar area revealed the periodic insertion of cell feet into the lens capsule with numerous vesicles. Cryosections of entire mouse eyes confirmed a similar looking structure. The structure appears in an area of basement membrane growth. A stylized foot-feet model is offered to help visualize the structure in 3D.
