Overview

This electron micrograph shows endocrine cells which secrete a peptide hormone. Hormone is stored in secretory granules and released into the extracellular space via the merocrine mode of secretion. The close association of these cells with a nearby fenestrated capillary facilitates the rapid entry of the hormones into the circulation. Endocrine pancreas 12,000x
