Sumario:Cultured bovine chromaffin cells have been tested as a successful neuroendocrine model to study the secretory process. Changes in the dynamics of the secretory vesicles and the exocytotic machinery microdomains could be studied in control and stimulated conditions using appropriate molecular tools such as fluorescent SNARE protein expression or fluorochrome vesicular labeling in these neuroendocrine cells. Since most of these changes occur in or near the plasma membrane, the use of the total internal reflection fluorescent microscopy (TIRFM) and the implement of particle motion analysis could be essential tools to study the structural and dynamic changes of secretory machinery related with its function in this exocytotic cell model.
