The pinealocytes of the human pineal gland: A light and electron microscopic study.
The pinealocytes of the pineal gland of children and adults were studied at both light and electron microscopic levels. The pinealocytes were classified into light and dark pinealocytes on the basis of their shape, nuclear infolding, cytoplasmic contents and staining density. The light pinealocytes outnumber the dark pinealocytes and both of them have thin processes. The light pinealocytes have...
متن کاملPresence of glial cells in the rat pineal gland: a light and electron microscopic immunohistochemical study.
Immunoperoxidase methods for the demonstration of three glial antigens, vimentin, glial fibrillary acidic protein, and S-100 protein, were applied to routine-fixed paraffin sections of rat pineal gland. A pre-embedding electron microscope immunoperoxidase method was also used to study the ultrastructural localization of S-100 protein in pineal cells. Light and electron microscopic results showe...
متن کاملElectron microscopic observations on the mouse pineal, with particular emphasis on its secretory nature.
The generally accepted view as to the nature of the mammalian pineal is that this organ has secretory activity, but the evidence available, especially the morphological one, is far from sufficient. Recently the pineal of various animal species has been examined repeatedly by electron microscopy (MILOFSKY 1957, GUSEK and SANTORO 1961, DE ROBERTIS and PELLEGRINO DE IRALDI 1961, ANDERSON 1965, GUS...
متن کاملAn Electron Microscopic Study on the Toad
In spite of numerous investigations, the nature and function of the subcommissural organ (SCO) located beneath the posterior commissure was not clear owing to poor staining methods, and for a long time this organ was regarded as one of the most mysterious organs. However, since recently a variety of special staining methods including GOMORI's chrome alum hematoxylin and other histochemical tech...
متن کاملScanning and transmission electron microscopic study on a multilayered basement membrane in the pineal organ of the ayu Plecoglossus altivelis.
The pineal organ possesses highly fenestrated capillaries, and is devoid of the so-called blood-brain barrier. The present study indicated that the pineal epithelium of the teleost fish, ayu Plecoglossus altivelis, possesses an unusually thick and convoluted basement membrane (2.2-2.4 microm in width) which is visible even under the light microscope. This pineal basement membrane was observed b...
