Ultrastructure of the vitreous body of the rabbit.
Examination in the scanning and the transmission electron microscope showed three morphologically and structurally different types of cells in the vitreous body of the healthy rabbit eye: 1. cells with numerous cytoplasm processes, whose high metabolic activity is represented by the presence of a large number of organelles and which are capable of synthesizing fibrillar material; 2. elongate cells with a flattened nucleus, with long, narrow cytoplasm processes arising from both their poles and with only a few organelles in their cytoplasm; 3. large spherical cells with structureless contents, whose nucleus and few organelles are situated below the cell membrane. The organized component of the intercellular matter of the rabbit vitreous body is composed of collagen fibrils with a very variable diameter (24-180 nm), The collagen fibrils form the basis of the three-dimensional skeleton of the intercellular matter of the vitreous body.
