Catecholamine-storing cells in the cyclostome heart.
نویسندگان
چکیده
The lamprey heart contains characteristic catecholamine-storing cells in both the atrium and the ventricle. Sufficient circumstantial evidence is available indicating that catecholamines together with protein carbohydrate complexes are contained in these cells within the membrane bound cytoplasmic granules. If the "recepto-secretory function" and "neuroectodermal origin" of these cells are proved, then they may be classified as typical paraneurons.

Electron and fluorescence microscopic study of specific granules in rat atrial muscle cells.
Many dense granules have been found in the cardiac muscle cells and in the specific cells which are present in the interstitial tissue of the cyclostome heart by electron microscopy (OSTLUND et al. 1960, BLOOM et al. 1961). Chemical analysis of these granules revealed a large amount of catecholamine contained in the granules (BLOOM et al. 1961). On the other hand, the presence of spherical, ele...
متن کاملCytochemical identification of endocrine thymus of chicken in relation to aging
Age related cytochemical changes of thymic endocrine cells were studied in 78 day old chicks at five day interval to age of day 60 employing a panel of cytochemical stains. Methenamine silver revealed cell morphology including cell processes distinctly while diamine silver revealed a stronger argentaffinity in these cells. The cells had greater affinity for diamine silver compared to methenamin...

s:3604:"During pregnancy, the placenta delivers "cord blood" to the baby through the umbilical cord serving as a lifeline of nourishment from the mother to baby. At birth, "cord blood" remains in the umbilical cord and placenta and until recently, had typically been discarded. The tragedy of this practice is that "cord blood" contains very special cells called "stem cells". Recent advances in m...
متن کاملEffect of heart failure on catecholamine granule morphology and storage in chromaffin cells
One of the key mechanisms involved in sympathoexcitation in chronic heart failure (HF) is the activation of the adrenal glands. Impact of the elevated catecholamines on the hemodynamic parameters has been previously demonstrated. However, studies linking the structural effects of such overactivation with secretory performance and cell metabolism in the adrenomedullary chromaffin cells in vivo h...
