Voorbeelden van endoplasmic reticulum

• Although plastids remained unchanged, further development of the endoplasmic reticulum was manifested by longer profiles.

• Nuclear profiles were markedly abnormal, plasmalemma withdrawal (arrowheads) could be seen and the profiles of endoplasmic reticulum were dilated (a).

• Note the smooth and rough endoplasmic reticulum and gap junctions between theca-interna cells.

• In the cortex of the oocytes the cisternae of the endoplasmic reticulum were no longer present.

• These complexes appear occasionally to be associated with vesicles of smooth endoplasmic reticulum.

• Microtubules and the endoplasmic reticulum are highly interdependent structures.

• The tegument is a syncytial stratum, laden with membrane-bound, electron-lucid and electron-dense vesicles, mitochondria, ribosomes and smooth endoplasmic reticulum.

• One interesting protein is calreticulin, a calcium-binding protein that, in mammals, is normally located in the endoplasmic reticulum.
