Rough endoplasmic reticulum

This electron micrograph shows a cell with extensive RER, indicating that it is actively synthesizing protein (translation) for secretion. At the light microscopic level, these regions of RER stain blue with hematoxylin. Also visible are mitochondria, lipid droplets, glycogen granules and a portion of the nucleus. Liver 8000x
