WebThe lens fibers make up the substance of the lens. They are hexagonal shaped cells that arise from the subcapsular epithelium and lose their nuclei and organelles, elongating until they reach a length of 7-10um. Eventually, the cells become filled with special lens proteins known as crystallins that increase the refractory index of the lens ... In anatomy, a crystallin is a water-soluble structural protein found in the lens and the cornea of the eye accounting for the transparency of the structure. It has also been identified in other places such as the heart, and in aggressive breast cancer tumors. Since it has been shown that lens injury may promote nerve regeneration, crystallin has been an area of neural research. So far, it has been demonstrated that crystallin β b2 (crybb2) may be a neurite-promoting factor.
