Die Nebenniere und das chromaffine System
1926Stammesgeschichtlich ist die Nebenniere zweifellos eine der jungsten Erwerbungen des Wirbeltierkorpers. Nur die Amnioten besitzen ein einheitliches, in sich abgeschlossenes Nebennierenorgan, das aus zwei scharf trennbaren Gewebsarten besteht, deren Zellen sich in innigster Beruhrung mit dunnwandigen Blutgefasen zu ein oder mehrzelligen Balken ...

Exocytosis Studies in a Chromaffin Cell‐Free System
Annals of the New York Academy of Sciences, 2002Abstract: We have developed a system for the real‐time study of regulated exocytosis in living, cultured bovine adrenal chromaffin cells (BCCs). Exocytosis was monitored by the use of total internal reflection fluorescence (TIRF) microscopy to image single large dense‐core secretory vesicles (LDCVs).

Chromaffin cells of the adrenal medulla were used to study the release of neurotrophic factors operationally defined by their capacity to promote the in vitro survival of embryonic neurons from the peripheral and central nervous system. Chromaffin cells are closely related to sympathetic neurons in terms of their transmitters and specific proteins and,

The cardiovascular chromaffin cell system of the southern hemisphere lamprey, Geotria australis gray
Journal of Morphology, 1985AbstractThis study demonstrates that the silver technique of Grimelius (Acta Soc. Med. Ups. 73:243–270, 68) is ideally suited for the study of cardiovascular chromaffin cells in lampreys. This method showed that in the Southern Hemisphere lamprey, Geotria australis, the distribution of chromaffin cells differs from that described for holarctic species.

On the autonomic nervous and chromaffin control systems of lungfish
Australian Zoologist, 2010There are currently three extant genera of true lungfish (dipnoans): one in South America (Lepidosiren), one in Africa (Protopterus) and one in Australia (Neoceratodus). Although there are numerous fish that can breathe air, a common feature of the dipnoans is a vascular arrangement with a pulmonary artery, and a pulmonary vein that brings the ...

Abstract The uptake of catecholamines was investigated in bovine adrenal chromaffin cells cultured for 2 and 7 days. These cells, after their attachment onto the collagen-coated plates, began to develop processes which progressively increased in length with time in culture. Process outgrowth of a few cells was apparent on day 2 in culture.

AbstractThe role of cytoskeletal elements in vesicle transport occurring during exocytosis was examined in adrenal medullary bovine chromaffin cells maintained in culture. Amperometric determination of depolarization‐dependent catecholamine release from individual intact cells treated with actin or myosin inhibitors showed alterations in the fast and ...

If severe enough, periods of acute stress in animals may be associated with the release of catecholamine hormones (noradrenaline and adrenaline) into the circulation; a response termed the acute humoral adrenergic stress response. The release of catecholamines from the sites of storage, the chromaffin cells, is under neuroendocrine control, the ...

On the chromaffin system of the African lungfish, Protopterus aethiopicus.
Acta physiologica Scandinavica, 1980The distribution of chromaffin tissue was studied in the African lungfish using Falck-Hillarp fluorescent histochemistry together with quantitative analysis of catecholamines in plasma and tissue extracts. Intensely fluorescent cells form chromaffin tissue in the wall of the atrium, the wall of the most anterior part of the left cardinal vein and the ...
