Abstract
Intermediate (10 nm) filaments are found in epithelial and cortical fiber cells of the rabbit lens, but are absent from the nuclear fiber cells. Actin filaments were identified in the epithelial cells. Although the backbone of the cortical fiber cell protein chains has the same size as the actin filament, its identification as actin remains to be resolved. These protein chains, which clumped in the nuclear fiber cells, are absent from the epithelial cells.
