Colorized transmission electron micrograph (TEM) of rough endoplasmic reticulum (ER) from an acinar cell in the pancreas.

Early transmission electron micrograph of a thin section of the ribosome-studded rough endoplasmic reticulum of guinea pig pancreas. The ribosomes (small dots) were originally called Palade particles...

Classic early transmission electron micrograph of a thin section of guinea pig pancreas showing ribosome-studded rough endoplasmic reticulum. Image made available by James D. Jamieson and the Depart...

Early transmission electron micrograph showing intracisternal granules with an electron density equal to that of zymogen granules found in rough endoplasmic the reticulum lumen (cisternae) of animals ...

Early transmission electron micrograph of a thin section of a secretory cell from guinea pig pancreas illustrating vesicle trafficking between the rough endoplasmic reticulum and Golgi apparatus (uppe...

Transmission electron micrograph of liver cells from a 3-day old rat showing extensive smooth and rough endoplasmic reticulum, and glycogen (dark rosettes). Image made available by James D. Jamieson a...

Transmission electron micrograph of rat liver showing rough endoplasmic reticulum, mitochondria, and glycogen granule rosettes. Image made available by James D. Jamieson and the Department of Cell Bi...

Transmission electron micrograph of a thin section of plastic-embedded material from the 'rough microsome' fraction of a preparation of rat liver. Subsequent to this early image, 'microsomes' became ...
