Rapid sprouting of filopodia in nerve terminals of chromaffin cells, PC12 cells, and dorsal root neurons induced by electrical stimulation.
The PCI 2 cell line is derived from an induced pheochromocytoma and, when grown in a serum-supplemented medium, PCI 2 cells exhibit many features of their normal counterparts, adrenal chromaffin cells (Greene and Tischler 1976).
Pheochromocytomas arise from the chromaffin cells of the adrenal gland.
Approximately 85% arise from chromaffin cells in the adrenal medulla, and 15% arise from chromaffin tissue in extra-adrenal sites extending from the neck to the pelvis, although most are found intra-abdominally.
In the second case, secretion of catecholamines from chromaffin tissues was suspected as the recent onset, severe high blood pressure resolved after surgery.
Cg A, isolated from chromaffin cells of the adrenal medulla, is an acidic glycoprotein with 439 amino acids (21) and is present in secretory dense core granules located within the cytoplasm of these NE cells (22), However, CgA production seems to depend on tumor type or tumor differentiation and the sensitivity of CgA detection in tissue or plasma may be low in moderately or poorly differentiated NE carcinomas (23).

This syndrome develops in three stages: during the first stage, 6-48 hours after the initial injury, one observes rapid decrease in size of the thymus, spleen, lymph glands, and liver; disappearance of fat tissue; edema formation, especially in the thymus and loose retroperitoneal connective tissue; accumulation of pleural and peritoneal transudate; loss of muscular tone; fall of body temperature; formation of acute erosions in the digestive tract, particularly in the stomach, small intestine, and appendix; loss of cortical lipoids and chromaffin substances from the adrenals; and sometimes hyperemia of the skin, exophthalmos, [and] increased lachrymation and salivation.
To evaluate the cytotoxic effect in cultured chromaffin cells, LDH release assay has been used by (Sicard et al.
