Dense-core vesicles (DCVs) are found in various types of cells, such as neurons, pancreatic β- cells, and chromaffin cells. These vesicles release transmitters, peptides, and hormones to regulate diverse functions, such as the stress response, immune response, behavior, and blood glucose levels. In traditional electron microscopy after chemical fixation, it is often reported that the dense cores occupy a portion of the vesicle toward the center and are surrounded by a clear halo.
