In searching for a clue to the role of actin filament bundles organized into polygonal arrays, or geodomes, in lens epithelial cells, we examined several physical events occurring in the young rabbit lens which may initiate their formation. We used N

Ultraviolet radiation in the near range (UVA) causes lens opacification and disrupts the actin cytoskeleton in rabbit and gray squirrel lenses. Changes were noted using transmission electron microscopy of tangential sections and rhodaminephalloidin f

The role of near-UV radiation as a cytoskeletal actin-damaging agent was investigated. Two procedures were used to analyse fresh smooth dogfish (Mustelus canis) eye lenses that were incubated for up to 22 hr in vitro, with elasmobranch Ringer's mediu

Since filamentous actin had been shown earlier to exist in lens epithelial and fiber cells, we inquired whether this could represent a contractile system with myosin and other actin-associated proteins. We resolved this question in freshly removed or

An indirect immunogold technique for transmission electron microscopy was used for localizing two cytoskeletal proteins, actin and vimentin, in the epithelium of freshly removed rabbit lens, especially in relation to the polygonal array structures lo

The pattern of localization of actin filaments was compared in whole mounts of lens epithelium of rabbit and mouse using the fluorescently-labeled actin-specific probe, rhodamine-phalloidin. In the adult rabbit lens, fluorescent polygonal arrays cons

Polygonal arrays of microfilaments have been discovered to line the inner apical plasma membrane of anterior epithelial cells of the intact rabbit lens. When tangential sections are studied with the electron microscope, the polygonal arrays are seen

The conditions providing for optimal preservation of the ultrastructure of the lens epithelium of embryonic and young chicks were sought, especially with regard to avoiding fixation artifacts and to enhancing the lens cytoskeleton. The optimal fixati

Actin filament patterns in lens epithelia from animals of various taxonomic groups were studied using rhodamine phalloidin fluorescence microscopy of epithelial whole mounts and transmission electron microscopy of tangential sections. The results wer
