Lamellar body-subsurface cistern complexes in the paraventricular nuclei of the hamster.

Structures identified as lamellar bodies and subsurface cisterns have been observed in the paraventricular nuclei of the hamster hypothalamus. These neuronal structures can be found in the cytoplasm as single organelles or forming lamellar body-subsurface cistern complexes, which are connected with the nuclear envelope. The morphological features of the complexes are described and their possible functional significance with regard to the ageing process are discussed.
