A three-dimensional study of organelle interrelationships in regenerating rat liver. 6. Golgi apparatus.
Luminal materials from the ER are supplied to the Golgi apparatus (GA) either via precisternal elements (PE) detaching from the ER and building up a first cisterna, or via direct luminal continuities with the sER. Membrane supply is believed to follow only the first of these two pathways. It is further argued that during the processing of luminal materials and membrane - two Golgi activities that proceed at a different rate - bits of membrane carrying the differentiation enzymes are recycled to less differentiated membranes in the form of Golgi vesicles (GV).
